Abstract: Abinawanto, Hamidah H, Bowolaksono A, Eprilurahman R. 2018. Short Communication: Biometric of freshwater crayfish (Cherax spp.) from Papua and West Papua,, Indonesia. Bio ersitas 19: 489-495. Freshwater crayfish, Cherax spp. is a native crayfish species in Papua, Indonesia. Biometric information of this crayfish species in Indonesia is limited. Hence, this study aimed to provide these data. Specimens were collected from West Papua Province, i.e., from Uter Lake (Atinjo Subdistrict, Maybrat) and Seremuk River (Haha Village, Seremuk Subdistrict, South Sorong), respectively. Besides, the specimens were also collected from Papua Province in Baliem River at Pike Village, Hubukiak Subdistrict, and Wesaput Village, Wesaput Subdistrict, Jayawijaya. Data were analyzed using canonical discriminant function (CDF). The results showed that the longest carapace of Cherax spp. was 97.83 mm found in Baliem River at Pike Village. CDF analysis showed that there were three population groups of Cherax spp. from four locations. The first group originated from Uter Lake (Atinjo Subdistrict) and Seremuk River (Haha village). The second group was from Baliem River (Pike Village Hubukiak Subdistrict, Jayawijaya and the third group from Baliem River (Wesaput Village Wesaput Subdistrict)

Abstract: Two new species of the genus Cherax are described and illustrated. Cheraxmosessalossa sp. n. , endemic to the Klademak Creek drainage in Sorong, in the western part of the Kepala Burung (Vogelkop) peninsula, West Papua, Indonesia, is described, figured and compared with its closest relatives, Cheraxmisolicus Holthuis, 1949 and Cheraxwarsamsonicus . The new species may be easily distinguished from both by the shape of the rostrum, the shape of the chelae, the presence of five cervical spines, the shape of the scaphocerite, and short scattered hairs on the carapace. Cheraxalyciae sp. n. , endemic to creeks in the Digul River drainage in the eastern part of the Boven Digoel Regency, Papua, Indonesia, is described, figured, and compared with its closest relative, Cheraxpeknyi Lukhaup & Herbert, 2008. The new species may be easily distinguished from Cheraxpeknyi by the shape of the chelae, presence of a soft patch on the chelae of the males, and colouration. A molecular phylogeny based on two mitochondrial gene fragments, 16S and COI, supports the morphology-based description of the two new species, which can also be clearly distinguished by sequence differences.

Abstract: The endemic Chelodina mccordi is considered extinct in the wild however, ex-situ populations are thriving and s led for our genetic ersity assessment. We used three sequences resulting from blood and tissue s les of five in idual turtles lified for 650-bp cytochrome oxidase I (COI) fragment of the mitochondrial DNA. We analysed a total of 30 barcoding DNA sequences for phylogenetic relationships and genetic distances among Chelodina spp . Nucleotide ersity of eight C. mccordi s les is 0.007 ± 0.001 with a haplotype ersity of 0.893 ± 0.086. All these s les form a monophyletic clade that is sister to a clade of Australian and New Guinean long-necked turtles. Genetic distances calculated using Kimura 2-paramater model among C. mccordi sequences range between 0.2% and 1.5%, while a few others are without distance. The shortest genetic distance is between in iduals from Rote Island, whereas the longest distance was found between in iduals, each of which was derived from parental stocks originating in Rote and Timor islands. A genetic distance of 1.1% - 1.5% is likely to denote distinction at subspecies level. Results of this study could help in reintroducing captive in iduals into their natural habitats. Thus, captive breeding programme of this species may help its conservation.

Total telah ditemukan sebanyak 20 jenis herpetofauna terdiri atas 10 jenis amfibia, 7 jenis lasertilia dan 3 jenis ophidia. Jenis tersebut antara lain yaitu: Fejervarya limnocharis, Fejervarya cancrivora, Occydozyga sumatrana, Occydozyga lima, Hylarana chalconota, Huia masonii, Limnonectes macrodon, Microhyla achatina, Phrynoidis aspera, Polypedates leucomystax, Bronchocela jubata, Eutropis multifasciata, Dasia olivacea, Hemidactylus platyurus, Hemidactylus frenatus, Hemidactylus garnoti, Cyrtodactylus marmoratus, Ahaetula prasina, Oligodon purpurascens, dan Rhabdophis chrysargos. Diketahui dari jenis-jenis tersebut dua jenis yaitu Huia masonii dan Microhyla achatina merupakan endemik Jawa. Hasil analisis didapatkan nilai indeks keanekeragaman sebesar 2,93 di mana tergolong tinggi. Sedangkan indeks kemerataan sebesar 0,43 yang menandakan persebaran herpetofauna di kawasan ekowisata Linggo Asri tidak merata dan terkonsentrasi beberapa titik. Tipe vegetasi dan ketinggian tempat merupakan faktor ekologi utama yang mempengaruhi penyebaran herpetofauna di kawasan ekowisata Linggo Asri.

Abstract: There are 42 species of turtles including sea turtle, freshwater turtle, tortoise, and softshell turtle (Reptilia: Testudines) living in Indonesia today. Turtles have economic values for quite a long time and it has led to illegal trade such as smuggling of carapace and plastron bones. Identification is needed to find out more details about the turtle species. Turtles have shells as unique features with different characteristics on each species. Shell’s identification usually relies on the shape of carapace and plastron. The purpose of this research is to understand turtle shell morphological characters and determine the diagnostic characters of each species. We conducted visual observation on specimen collections from the Laboratory of Animal Systematics, Faculty of Biology, Universitas Gadjah Mada and Museum of Biology, Faculty of Biology, Universitas Gadjah Mada. The result shows that each turtle species have their own unique shell bone’s characters, therefore it can be used to determine each turtle species of Indonesia.

Abstract: The frog genus Microhyla was considered as the South, East, and Southeast Asian frog species. Microhyla orientalis was described in 2013, distributed in Java and Bali, Indonesia. Thenceforth, it was known as the easternmost distribution of this genus within the oriental region, but recently this species was recorded from the Timor Island and Sulawesi on the Wallace regions. We applied molecular analysis to evaluate the taxonomic status and the origin of the Wallacean population. Phylogenetic analysis using the partial 16S mitochondrial gene demonstrated that the Java, Timor and Sulawesi populations were not significantly different from the Bali population. This Wallacean population of M. orientalis was originated from Java and possibly it is accidentally distributed by humans through the expansion of agricultural activity.

Abstract: A tiny new species of narrow-mouthed frog of the genus Microhyla is described from the island of Belitung and southeastern Sumatra, Indonesia. The most distinctive feature of the new frog is its diminutive adult size, snout-vent length ranging only from 12.3 to 15.8 mm in adult males. Phylogenetic analyses based a fragment of the mitochondrial 16S rRNA gene, along with detailed morphological and acoustic comparison differentiate the new taxon from all known congeners. The new species, formally described as Microhyla sriwijaya sp. nov., is a member of the M. achatina species group and the sister taxon to M. orientalis. It is diagnosable from other congeners by a combination of characters: (1) smaller male snout-vent size 16 mm (2) snout obtusely rounded in dorsal view (3) absence of mid-dorsal line and skin fold (4) first finger reduced (finger I length less than half of finger II length) (5) dorsum with a prominent dark median mark extending posteriorly, narrow anteriorly near the level of the shoulder and expanding dorsolaterally up to the vent margins of the dorsal marking concave with broad reddish-brown or orange colouration on either side (6) foot webbing rudimentary, reaching just up to the first subarticular tubercle on all toes (7) dorsal skin with prominent tubercles, especially in life (8) tibiotarsal articulation of adpressed limb reaching beyond the snout tip and (9) males produce a single type of call with pulsatile temporal structure, calls of relatively short duration ranging between 31.8–62.8 s, with two to three pulses delivered at a rate ranging between 32.2–36.0 pulses per second, and the mean overall dominant frequency of 4.3 kHz. The uncorrected pairwise genetic distances between Microhyla sriwijaya sp. nov. and all other known congeners are 3.8% for the studied 16S gene fragment. The new species was discovered from wayside rural areas with oil palm plantations at four localities in the small island of Belitung (type locality), and from coffee plantation and secondary forest at L ung in southeastern Sumatra. It is not known from any protected area and appears to be threatened due to tin mining activity, intensive logging, oil palm, and other commonly practiced agriculture activities.
