Abstract: Only a single blind species is known in the centipede family Scolopendridae, representing the monotypic genus Tonkinodentus Schileyko, 1992, from Vietnam. All of more than 400 other species have four ocelli on each side of the cephalic plate. A complex of three new blind species of the genus Cormocephalus Newport, 1844, is described from the subterranean fauna of the central Pilbara region of Western Australia. Phylogenies based on sequence data for the barcode region of COI and a concatenated matrix that also includes 12S rRNA, 28S rRNA and ITS2 unite the blind Pilbara species as a monophyletic group, albeit with moderate bootstrap support, informally named the C. sagmus species group. Cormocephalus sagmus, C. pyropygus and C. delta spp. nov. supplement 17 epigean congeners previously described from Australia. The new species are all morphologically similar, but can be distinguished using the shape and spinulation of the ultimate leg prefemur. Two additional genetically distinct lineages were recovered that are not described, owing to the specimens being immature or lacking diagnostic morphological characters. The subterranean radiation in the Pilbara is more closely related to species from forests in the south-west of Western Australia than to congeners from the arid zone. rn:lsid:zoobank.org:pub:6F67FD31-A373-4DC5-A5FD-374D32DEE02C

Abstract: Birds harbour a wide array of other taxa in their nests or in their plumage, which either have an ectoparasitic or commensal relationship with the host. We report on the discovery of a cheliferid pseudoscorpion found in the plumage and nests of the sociable weaver bird (Philetairus socius) in southern Africa. The nests of these communal birds are the largest of any bird, and may contain up to 500 in iduals. The pseudoscorpion is likely to have a mutualistic relationship with the birds, most likely preying on other small invertebrates in the nests. Molecular data derived from two populations of the pseudoscorpion found ergence levels of 1.1% in cytochrome oxidase 1 (CO1), and an analysis of CO1 and two rRNA genes (18S and 28S) found a close relationship with Chelifer and Parachelifer in the tribe Cheliferini, which is supported by the morphology of the male genitalia. The molecular analysis also suggests that Beierius may not belong to the Cheliferini. The pseudoscorpion found in association with the sociable weaver represents a new genus and species, Sociochelifer metoecus Harvey, sp. nov.

Abstract: The aganippine shield-backed trapdoor spiders of the monophyletic nigrum -group of Idiosoma Ausserer s. l. are revised, and 15 new species are described from Western Australia and the Eyre Peninsula of South Australia: I.arenaceum Rix & Harvey, sp. n. , I.corrugatum Rix & Harvey, sp. n. , I.clypeatum Rix & Harvey, sp. n. , I.dandaragan Rix & Harvey, sp. n. , I.formosum Rix & Harvey, sp. n. , I.gardneri Rix & Harvey, sp. n. , I.gutharuka Rix & Harvey, sp. n. , I.incomptum Rix & Harvey, sp. n. , I.intermedium Rix & Harvey, sp. n. , I.jarrah Rix & Harvey, sp. n. , I.kopejtkaorum Rix & Harvey, sp. n. , I.kwongan Rix & Harvey, sp. n. , I.mcclementsorum Rix & Harvey, sp. n. , I.mcnamarai Rix & Harvey, sp. n. , and I.schoknechtorum Rix & Harvey, sp. n. Two previously described species from south-western Western Australia, I.nigrum Main, 1952 and I.sigillatum (O. P.-Cambridge, 1870), are re-illustrated and re-diagnosed, and complementary molecular data for 14 species and seven genes are analysed with Bayesian methods. Members of the nigrum -group are of long-standing conservation significance, and I.nigrum is the only spider in Australia to be afforded threatened species status under both State and Commonwealth legislation. Two other species, I.formosum Rix & Harvey, sp. n. and I.kopejtkaorum Rix & Harvey, sp. n. , are also formally listed as Endangered under Western Australian State legislation. Here we significantly relimit I.nigrum to include only those populations from the central and central-western Wheatbelt bioregion, and further document the known ersity and conservation status of all known species.

Abstract: Compared with araneomorph spiders, relatively few mygalomorph spiders have evolved an obligate existence in subterranean habitats. The trapdoor spider genus Troglodiplura Main, 1969 and its sole named species T. lowryi Main, 1969 is endemic to caves on the Nullarbor Plain of southern Australia, and is one of the world’s most troglomorphic mygalomorph spiders. However, its systematic position has proved to be difficult to ascertain, largely due to a lack of preserved adults, with all museum specimens represented only by cuticular fragments, degraded specimens or preserved juveniles. The systematic placement of Troglodiplura has changed since it was first described as a member of the Dipluridae, with later attribution to Nemesiidae and then back to Dipluridae. The most recent hypothesis specifically allied Troglodiplura with the Neotropical subfamily Diplurinae, and therefore was assumed to have no close living relatives in Australia. We obtained mitochondrial sequence data from one specimen of Troglodiplura to test these two competing hypotheses, and found that Troglodiplura is a member of the family Anamidae (which was recently separated from the Nemesiidae). We also reassess the morphology of the cuticular fragments of specimens from several different caves, and hypothesise that along with T. lowryi there are four new troglobitic species, here named T. beirutpakbarai Harvey & Rix, T. challeni Harvey & Rix, T. harrisi Harvey & Rix, and T. samankunani Harvey & Rix, each of which is restricted to a single cave system and therefore severely threatened by changing environmental conditions within the caves. The first descriptions and illustrations of the female spermathecae of Troglodiplura are provided. The family Anamidae is further ided into two subfamilies, with the Anaminae Simon containing Aname L. Koch, 1873, Hesperonatalius Castalanelli, Huey, Hillyer & Harvey, 2017, Kwonkan Main, 1983, Swolnpes Main & Framenau, 2009 and Troglodiplura, and the Teylinae Main including Chenistonia Hogg, 1901, Namea Raven, 1984, Proshermacha Simon, 1909, Teyl Main, 1975 and Teyloides Main, 1985.

Abstract: The trapdoor spider family Nemesiidae comprises 14 genera in Australia, the majority of which are included in the subfamily Anaminae. Here we provide evidence from a multigene molecular analysis of most Australian genera of Anaminae for a previously unrecognised clade that also differs from its sister-genus, Aname L. Koch, by the lack of a prominent asetose ventral depression on the pedipalpal tibia and the medium-sized mating spur on tibia I of males. This depression is a characteristic of all species of Aname examined to date, and represents a newly recognised character system in the subfamily. The new genus, named Hesperonatalius, is represented by three new species – H. maxwelli, sp. nov., H. harrietae, sp. nov. and H. langlandsi, sp. nov. – all from arid Western Australia. zoobank.org/References/D5352390-5D21-49DD-A123-A074422EB860

Abstract: Australian carp gudgeons (Hypseleotris spp.) of the Murray–Darling basin are a species complex including sexually reproducing taxa and unisexual hybrid lineages that reproduce via hybridogenesis. Unisexual fish require gametes of a sexual species to propagate themselves and can be regarded as ‘sexual parasites’ capable of driving closed populations to extinction. Metapopulation dynamics have been proposed as a mechanism that could facilitate coexistence between a sexual parasite and its ‘host’. This study evaluates whether patterns of spatial genetic variation are compatible with metapopulation dynamics for a sexually reproducing member of the carp gudgeon complex (Hypseleotris sp. HA), in the Granite Creeks system of central Victoria. Genetic differentiation of fish among all study sites was accommodated by a model of migration-drift equilibrium using decomposed pairwise regression analysis. Given that the population was ided into discrete patches in the form of refugial waterholes during the time of this study, we infer that spatially constrained source–sink metapopulation dynamics may be responsible for producing this pattern. It is therefore possible that metapopulation dynamics contribute to coexistence in the Granite Creeks carp gudgeon hybridogenetic system, and further analysis is required to determine the relative importance of environmental versus demographic factors towards patch extinction.

Abstract: The methods used to detect and describe morphologically cryptic species have advanced in recent years, owing to the integrative nature of molecular and morphological techniques required to elucidate them. Here we integrate recent phylogenomic work that sequenced many genes but few in iduals, with new data from mtDNA and morphology from hundreds of gecko specimens of the Gehyra variegata group from the Australian arid zone. To better understand morphological and geographical boundaries among cryptic forms, we generated new sequences from 656 Gehyra in iduals, largely assigned to G. variegata group members over a wide area in Western Australia, with especially dense s ling in the Pilbara region, and combined them with 566 Gehyra sequences from GenBank, resulting in a dataset of 1,222 specimens. Results indicated the existence of several cryptic species, from new species with diagnostic morphological characters, to cases when there were no useful characters to discriminate among genetically distinctive species. In addition, the cryptic species often showed counter-intuitive distributions, including broad sympatry among some forms and short range endemism in other cases. Two new species were on long branches in the phylogram and restricted to the northern Pilbara region: most records of the moderately sized G. incognita sp. nov. are near the coast with isolated inland records, whereas the small-bodied saxicoline G. unguiculata sp. nov. is only known from a small area in the extreme north of the Pilbara. Three new species were on shorter branches in the phylogram and allied to G. montium . The moderately sized G. crypta sp. nov. occurs in the western and southern Pilbara and extends south through the Murchison region this species was distinctive genetically, but with wide overlap of characters with its sister species, G. montium . Accordingly, we provide a table of diagnostic nucleotides for this species as well as for all other species treated here. Two small-bodied species occur in isolated coastal regions: G. capensis sp. nov. is restricted to the North West Cape and G. ocellata sp. nov. occurs on Barrow Island and other neighbouring islands. The latter species showed evidence of introgression with the mtDNA of G. crypta sp. nov., possibly due to recent connectivity with the mainland owing to fluctuating sea levels. However, G. ocellata sp. nov. was more closely related to G. capensis sp. nov. in the phylogenomic data and in morphology. Our study illustrates the benefits of combining phylogenomic data with extensive screens of mtDNA to identify large numbers of in iduals to the correct cryptic species. This approach was able to provide sufficient s les with which to assess morphological variation. Furthermore, determination of geographic distributions of the new cryptic species should greatly assist with identification in the field, demonstrating the utility of s ling large numbers of specimens across wide areas.

Abstract: Southern smelts (Retropinna spp.) in coastal rivers of Australia are facultatively diadromous, with populations potentially containing in iduals with diadromous or wholly freshwater life histories. The presence of diadromous in iduals is expected to reduce genetic structuring between river basins due to larval dispersal via the sea. We use otolith chemistry to distinguish between diadromous and nondiadromous life histories and population genetics to examine interbasin connectivity resulting from diadromy. Otolith strontium isotope ((87) Sr:(86) Sr) transects identified three main life history patterns: hidromy, freshwater residency and estuarine/marine residency. Despite the potential for interbasin connectivity via larval mixing in the marine environment, we found unprecedented levels of genetic structure for an hidromous species. Strong hierarchical structure along putative taxonomic boundaries was detected, along with highly structured populations within groups using microsatellites (FST = 0.046-0.181), and mtDNA (ΦST = 0.498-0.816). The presence of strong genetic sub ision, despite the fact that many in iduals reside in saline water during their early life history, appears incongruous. However, analysis of multielemental signatures in the otolith cores of diadromous fish revealed strong discrimination between river basins, suggesting that diadromous fish spend their early lives within chemically distinct estuaries rather than the more homogenous marine environment, thus avoiding dispersal and maintaining genetic structure.

Abstract: In Australia, climate change and continental drift have given rise to a complex biota comprising mesic specialists, arid-adapted lineages, and taxa that have arrived on the continent from Asia. We explore the phylogenetic ersity and biogeographic history of the Australian trapdoor spider genus Conothele Thorell, 1878 that is widespread in Australia’s monsoonal tropics and arid zone. We sequenced three mtDNA and five nuDNA markers from 224 specimens. We reconstructed the phylogenetic relationships among specimens and estimated the number of operational taxonomic units (OTUs) using species delimitation methods. The timing of ergences was estimated and ancestral area reconstructions were conducted. We recovered 61 OTUs, grouped into four major clades a single clade represented by an arboreal ecomorph, and three fossorial clades. The Australian Conothele had a crown age of ~19 million years, and ancestral area reconstructions showed a complex history with multiple transitions among the monsoonal tropics, central arid zone, south-west and Pilbara bioregion. Conothele arrived on the continent during periods of biotic exchange with Asia. Since then, Conothele has colonised much of the Australian arid and monsoonal zones, during a period of climatic instability. The Pilbara bioregion harbours high lineage ersity, emphasising the role of climate refugia.

Abstract: The utility of restriction-site associated DNA sequencing (RADseq) to resolve fine-scale population structure was tested on an abundant and vagile fish species in a tropical river. Australia's most widespread freshwater fish, the "extreme disperser" Leiopotherapon unicolor was s led from 6 locations in an unregulated system, the Daly River in Australia's Northern Territory. Despite an expectation of high connectivity based on life history knowledge of this species derived from arid zone habitats, L. unicolor was not a panmictic population in the tropical lower Daly. Using ~14000 polymorphic RADseq loci, we found a pattern of upstream versus downstream population sub ision and evidence for differentiation among tributary populations. The magnitude of population structure was low with narrow confidence intervals (global FST = 0.014 95% CI = 0.012-0.016). Confidence intervals around pairwise FST estimates were all nonzero and consistent with the results of clustering analyses. This population structure was not explained by spatially heterogeneous selection acting on a subset of loci, or by s ling groups of closely related in iduals (average within-site relatedness ≈ 0). One implication of the low but significant structure observed in the tropics is the possibility that L. unicolor may exhibit contrasting patterns of migratory biology in tropical versus arid zone habitats. We conclude that the RADseq revolution holds promise for delineating subtle patterns of population sub ision in species characterized by high within-population variation and low among-population differentiation.

Abstract: The pseudoscorpions of the genus Garypus L. Koch are restricted to seashore habitats where they occupy supralittoral and littoral zones primarily in tropical and subtropical areas. Few species have been recorded from the Indo-West Pacific region, and this project was devised to produce a review of the species found in museum collections and to test the relationships of the various garypid genera using a molecular analysis and an assessment of their morphology. A new subfamily classification is proposed with the subfamilies Garypinae, including Garypus and the new genus Anchigarypus Harvey (type species Garypus californicus Banks), and the Synsphyroninae for the other genera (Ammogarypus Beier, Anagarypus Chamberlin, Elattogarypus Beier, Eremogarypus Beier, Meiogarypus Beier, Neogarypus Vachon, Paragarypus Vachon, Neogarypus Vachon, Synsphyronus Chamberlin, and Thaumastogarypus Beier). The species-level revision of Garypus provides evidence for at least 14 species, most of which are known from only single localities. The following species are redescribed: G. insularis Tullgren from the Seychelles, G. krusadiensis Murthy & Ananthakrishnan from India and Sri Lanka, G. longidigitus Hoff from Queensland, Australia, G. mal ensis Pocock from the Mal es, G. nicobarensis Beier from the Nicobar Islands and G. ornatus Beier from the Marshall Islands. The holotype of G. insularis is a tritonymph, and not therefore readily identifiable. Nine new species are described: G. latens Harvey, sp. nov., G. malgaryungu Harvey, sp. nov., G. necopinus Harvey, sp. nov., G. postlei Harvey, sp. nov., G. ranalliorum Harvey, sp. nov. and G. weipa Harvey, sp. nov. from northern Australia, G. dissitus Harvey, sp. nov. from Cocos-Keeling Island, G. reong Harvey, sp. nov. and G. yeni Harvey, sp. nov. from Indonesia. A further possible new species from Queensland is described but not named, as it is represented by a single tritonymph. The subspecies of the Caribbean species G. bonairensis Beier are elevated to full species status: G. bonairensis, G. realini Hummelinck and G. withi Hoff. We supplement the descriptions with sequence data from five specimens from four species of Garypus and two species of Anchigarypus, and find COI ergence levels of 7–19% between Garypus species. zoobank.org/References/16463E29-6F13-4392-9E41-46A4312C852B

Abstract: The number of subterranean taxa discovered in the north of Western Australia has substantially increased due to the requirements for environmental surveys related to mining development. Challenges in estimating subterranean bio ersity and distributions are related to lack of knowledge of taxa with convergent morphological characters in a largely unobservable ecosystem setting. An integrated approach is warranted to understand such complexity. Bathynellidae occur in most Australian aquifers, but only one species has been described so far, and the group lacks a reliable taxonomic framework. A new genus and one new species from the Pilbara region of Western Australia, Pilbaranella ethelensis, gen. et sp. nov., is described using both morphological and molecular data. Three additional species of Pilbaranella are defined through mitochondrial and nuclear genes, using Automatic Barcode Gap Discovery and Poisson Tree Processes species delimitation methods. A comparison of morphology and 18S rRNA sequences between Pilbaranella, gen. nov. and known lineages provides the evidentiary basis for the decision to establish a new genus. This study provides a morphological and molecular framework to work with Bathynellidae, especially in Australia where a highly erse fauna remains still undescribed.

Abstract: The phylogenetic relationships of the Australian species of Feaellidae are assessed with a molecular analysis using mitochondrial (CO1) and nuclear (ITS2) data. These results confirm the morphological analysis that three previously undescribed species occur in the Pilbara bioregion, which are named and described: Feaella (Tetrafeaella) callani, sp. nov., F. (T.) linetteae, sp. nov. and F. (T.) tealei, sp. nov. The males of these three species, as well as males of F. anderseni Harvey and other unnamed species from the Kimberley region of north-western Australia, have a pair of enlarged, thick-walled bursa that are not found in other feaellids. Despite numerous environmental impact surveys for short-range endemic invertebrates in the Pilbara, very few specimens have been collected, presumably due to their relictual distributions, restricted habitat preferences and low densities. rn:lsid:zoobank.org:pub:131F0587-F2EE-405F-BE5A-772F072D9915

Abstract: The contemporary and historical colonization capacity of an Australian freshwater fish, north-west glassfish Ambassis sp., was tested using mtDNA sequence data and six newly developed microsatellite loci in an endoreic basin in central Australia. Overall, Ambassis sp. exhibited weak genetic structure within catchments, suggesting some capacity to recolonize extirpated waterholes after disturbance. Genetic structure revealed that the historical pattern of connectivity among catchments in the Lake Eyre Basin was dramatically different from other species studied in this region. Two highly ergent clades were detected in separate catchments in the basin. mtDNA from in iduals s led in catchments north of the Lake Eyre Basin suggest that Ambassis sp. has colonized on two separate occasions from catchments in northern Australia, subsequently generating two highly ergent lineages.

Abstract: The species of the millipede genus Antichiropus Attems, 1911 found in the Pilbara region of Western Australia are reviewed, and 33 new species are described. The new species are: A. anguinus Car, n. sp., A. antius Car, n. sp., A. apricus Car, n. sp., A. cirratus Car, n. sp., A. confragus Car, n. sp., A. cristatus Car, n. sp., A. cucumeraceous Car, n. sp., A. cunicularis Car, n. sp, A. echinus Car, n. sp., A. filiolus Car, n. sp., A. forcipatus Car, n. sp., A. georginae Car, n. sp., A. gibbus Car, n. sp., A. hystricosus Car, n. sp., A. julianneae Car, n. sp., A. literulus Car, n. sp., A. lucyae Car, n. sp., A. nicholasi Car, n. sp., A. nimbus Car, n. sp., A. patriciae Car, n. sp., A. pendiculus Car, n. sp., A. picus Car, n. sp., A. procerus Car, n. sp., A. quaestionis Car, n. sp., A. rupinus Car, n. sp., A. salutus Car, n. sp., A. servulus Car, n. sp., A. simmonsi Car, n. sp., A. sloanae Car, n. sp., A. spathion Car, n. sp., A. uvulus Car, n. sp., A. verutus Car, n. sp. and A. vindicatus Car, n. sp.. The number of described Antichiropus species now stands at 72. Two species (A. julianneae Car, n. sp. and A. pendiculus Car, n. sp.) lack one diagnostic feature of the genus, namely a solenomere process, but are included here because they conform to the genus definition in all other characters. We also obtained sequence data from four mitochondrial genes (cytochrome c oxidase subunit 1 [COI], cytochrome c oxidase subunit 3 [COIII], cytochrome B [CytB], and 12S rRNA [12S]), and one nuclear gene (28S rRNA [28S]) for 19 species. Three main clades were recovered: one in the northern Pilbara, one in the southern Pilbara, and one just outside the south-western margin of the Pilbara.

Abstract: Fully troglobitic pseudoscorpions are rare in the Afrotropical Region, and we explored the identity and phylogenetic relationships of specimens of a highly modified troglobite of the family Gymnobisiidae in the dark zone of the Wynberg Cave system, on Table Mountain, South Africa. This large pseudoscorpion – described as Gymnobisium inukshuk Harvey & Giribet, sp. nov. – lacks eyes and has extremely long appendages, and has been found together with other troglobitic fauna endemic only to this cave system. Phylogenetic analyses using the nuclear ribosomal genes 18S rRNA and 28S rRNA and the mitochondrial protein-encoding gene cytochrome c oxidase subunit I unambiguously place the new species with other surface Gymnobisium from South Africa. This placement receives strong support and is stable to analytical treatments, including static and dynamic homology, parsimony and maximum likelihood, and data removal for ambiguously aligned sites. This species is the first troglobitic species of the family and one of the most highly modified pseudoscorpions from the Afrotropical Region. rn:lsid:zoobank.org:pub:5227092B-A64B-4DB3-AD90-F474F0BA6AED

Abstract: The formation of the Australian arid zone, Australia's largest and youngest major biome, has been recognized as a major driver of rapid evolutionary radiations in terrestrial plants and animals. Here, we investigate the phylogenetic ersity and evolutionary history of subterranean short-tailed whip scorpions (Schizomida: Hubbardiidae), which are a significant faunal component of Western Australian hypogean ecosystems. We sequenced two mitochondrial (12S, COI) and three nuclear DNA markers (18S, 28S, ITS2) from ∼600 specimens, largely from the genera Draculoides and Paradraculoides, including 20 previously named species and an additional 56 newly identified operational taxonomic units (OTUs). Phylogenetic analyses revealed a large and rapid species radiation congruent with Cenozoic aridification of the continent, in addition to the identification of a new genus in Western Australia and the first epigean schizomid from the Pilbara. Here, we also synonymise Paradraculoides with Draculoides (new synonymy), due to paraphyly and a lack of reliable characters to define the two genera. Our results are consistent with multiple colonisations of the subterranean realm from epigean ancestors as their forest habitat fragmented and retracted, with ongoing fragmentation and ersification of lineages underground. These findings illustrate the remarkable ersity and high incidence of short-range endemism of Western Australia's subterranean fauna, which has important implications for identifying and managing short-range endemic subterranean fauna. They also highlight the advantages of including molecular data in subterranean fauna surveys as all specimens can be utilized, regardless of sex and life stage. Additionally, we have provided the first multi-gene phylogenetic framework for Australian schizomids, which will enable researchers and environmental consultants to identify new taxa or align them to existing lineages.

Abstract: The schizomid fauna of mainland Australia currently comprises 60 species within seven named genera, of which five are endemic to the continent: Attenuizomus Harvey, 2000, Brignolizomus Harvey, 2000, Draculoides Harvey, 1992, Julattenius Harvey, 1992, Notozomus Harvey, 2000. Most Australian schizomids have been described from eastern and northern Australia, but there is also a significant subterranean fauna that has been found in hypogean habitats in the semi-arid Pilbara region of Western Australia. The vast majority of these species can be assigned to the genus Draculoides and this study is the first in a proposed series to revise this highly erse genus. We treat the species found in the western Pilbara region, which includes 13 new species and 13 previously named species, using morphological characters and multi-locus sequence data. We also incorporate a molecular “mini-barcode” approach for COI, 12S and ITS2 to diagnose the new species. The new species are named: Draculoides akashae Abrams and Harvey, n. sp., D. belalugosii Abrams and Harvey, n. sp., D. carmillae Abrams and Harvey, n. sp., D. christopherleei Abrams and Harvey, n. sp., D. claudiae Abrams and Harvey, n. sp., D. immortalis Abrams and Harvey, n. sp., D. karenbassettae Abrams and Harvey, n. sp., D. mckechnieorum Abrams and Harvey, n. sp., D. minae Abrams and Harvey, n. sp., D. noctigrassator Abrams and Harvey, n. sp., D. nosferatu Abrams and Harvey, n. sp., D. piscivultus Abrams and Harvey, n. sp. and D. warramboo Abrams and Harvey, n. sp. We also provide the first descriptions of males of D. anachoretus (Harvey, Berry, Edward and Humphreys, 2008) and D. gnophicola (Harvey, Berry, Edward and Humphreys, 2008). All of the new species are subterranean-dwelling, short-range endemic species that occur in regions subject to mining activities, rendering them of high conservation significance.
