Kongkang Baram (Pulchrana baramica) pertama kali dideskripsikan pada tahun 1900 di Sungai Baram Sarawak, Malaysia. Jenis ini tersebar luas di Semenanjung Malaysia, Singapura, Sumatera, Kepulauan Riau, Pulau Bangka, Kalimantan, dan Jawa. Sebelumnya, selama lebih dari 24 tahun informasi persebaran P. baramica di Pulau Jawa hanya diketahui dari Cilebut, Kabupaten Bogor berdasarkan catatan satu spesimen saja di Museum Zoologicum Bogoriense. Penelitian ini bertujuan untuk memberikan informasi terbaru catatan spesimen katak P. baramica dari Jawa dengan pendekatan morfologi dan morfometrika, dengan spesimen acuan populasi Sumatera dan Kalimantan. Metode analisis yang digunakan dalam penelitian ini, yaitu menggunakan PCA (Principal Component Analysis) kemudian dilakukan uji lanjut Duncan. Hasil penelitian ini menunjukkan beberapa variasi karakter yang membedakan P. baramica spesimen dari Jawa dari populasi Sumatera dan Kalimantan adalah berdasarkan karakter-karakter meristik identifikasi yang terlihat pada selaput renang tungkai belakang (webbing) yang lebih lebar pada jari kedua bagian luar, terdapatnya kelenjar pineal (pineal spot) yang sangat jelas, dan tekstur kulitnya cenderung lebih halus. Secara morfometrika terdapat 7 karakter pembeda antar populasi P. baramica dari Jawa, Sumatera, dan Kalimantan yang berupa karakter Lebar Kepala (HL), Jarak antar canthal (ICD), Panjang Tungkai Depan dari Bahu (FLL), Panjang Tulang Kering (TL), Jarak antar Lubang Hidung (IN), Jarak antar Ujung Mata ke Lubang Hidung (EN), dan Jarak antar mata (IOD).

Two of the six Chirixalus species currently known are distributed in Indonesia. Both species are only known to be distributed in Java, and they are Chirixalus trilaksonoi and Chirixalus pantaiselatan. During two field expeditions conducted in 2022 in Palembang, South Sumatra, we encountered several individuals exhibiting morphological similarities to C. trilaksonoi. Subsequent analysis, encompassing molecular, morphological, and bioacoustic, was undertaken to ascertain the identity of these individuals. The analyses outcomes unequivocally confirm that the specimens from Palembang are indeed C. trilaksonoi. Nevertheless, slight variations were observed between the Javanese and Sumatran populations of C. trilaksonoi. These populations exhibited a low genetic distance of 0.6% in mitochondrial DNA and displayed three polymorphic sites. Furthermore, there are slight differences in various morphological characteristics, and in advertising calls. The IUCN red-list status of this species was also evaluated, and based on the available evidence, we propose C. trilaksonoi as Vulnerable according to criteria B1ab(iii). This study stresses the importance of comprehensive taxon studies, especially in neighboring island, and in one biogeographical region.

We describe a new species of water snake genus Hypsiscopus that was formerly placed in the genus Enhydris from Towuti Lake, South Sulawesi, based on six specimens collected in 2003 and a specimen collected in 2019. The new species has several significant differences from other species in the genus Hypsiscopus (H. matannensis, H. plumbea, and H. murphyi) in possessing laterally compressed tail, higher number of scale rows in mid body, higher number of ventral scales, lower number of subcaudal scales, and distinct color pattern. The new species is likely distributed only in the Towuti Lake, and has higher level endemicity compared to H. matannensis. Further studies on the population and distribution are needed to evaluate its conservation status.

Leptobrachium from Southeast Asian populations previously were recognized as a single speciesLeptobrachium hasseltii Tschudi. Taxonomic reassessment revealed that Leptobrachium consists of somecryptic species due to similarities in their morphological appearance but diverse in molecular characters.Among the Indonesian populations, Leptobrachium was split into seven species (L. hasseltii, L. nigrops,L. waysepuntiense, L. hendricksoni, L. ingeri, L. abbotti, and L. montanum). Specifically, L. hasseltii isseparated into two groups; the Sumatran-Javan and the Bali populations. In this study, we analyzed themorphological data of 100 individuals of Leptobrachium to evaluate their morphological differences.The morphological differences expressed by analysis of variance (ANOVA) and principal componentanalysis (PCA) revealed significant differences between each Leptobrachium and four morphologicalcharacters suitable for species identification (the iris color, color pattern, humeral and femoral gland).The morphological differences also showed that the Bali population probably is undescribed species.

Roti buaya merupakan roti khas Betawi yang selalu muncul di upacara pernikahan masyarakat Betawi. Penggunaan roti buaya dalam upacara pernikahan masyarakat Betawi merupakan pengetahuan lokal yang sudah dilakukan secara turun-temurun. Simbol kesetiaan merupakan makna yang muncul dari roti buaya. Artikel inibertujuan untuk melihat integrasi pengetahuan lokal dan ilmu pengetahuan yang terlihat dalam penggunaan roti buaya dalam pernikahan Betawi. Karakter buaya dalam roti buaya dikaitkan dengan karakter buaya di alam. Penelitian ini dilakukan melalui dua metode, yaitu wawancara dan studi literatur. Dari data yang terkumpul diketahui bahwa jenis buaya yang digambarkan dalam roti buaya adalah buaya muara (Crocodylus porosus). Karakter buaya yang dapat hidup di darat dan di air, ukuran buaya betina lebih kecil dari buaya jantan, merupakan karakter buaya yang digambarkan dalam roti buaya, dan sesuai dengan karakter buaya di alam. Simbol buaya sebagai simbol kesetiaan hanya sesuai ketika buaya ditempatkan dalam sistem kandang pasangan. Meskipun begitu, pemahaman buaya sebagai simbol kesetiaan tetap dipegang oleh masyarakat Betawi. Hal ini ditandai dengan penggunaan roti buaya dalam pernikahan yang bertahan hingga sekarang

Baram River Frog (Pulchrana baramica) is a ranid species distributed in the Malay Peninsula, Borneo, Sumatra and represents the sole species from the genus Pulchrana on Java Island. Cryptic species are commonly encountered within the amphibian group which can cause confusion in the identification process. Due to the broad distribution range of P. baramica and the frequent occurrence of cryptic species within the amphibian group, it is important to evaluate the taxonomic status of P. baramica. Therefore, we investigated the taxonomic position of P. baramica from three populations (Kalimantan, Sumatra, and Java) and identified the interpopulation genetic variation based on molecular data of the 16S mitochondrial gene. We reconstructed phylogenetic relationships using Neighbour Joining, Maximum Likelihood, and Bayesian Inference. The research results revealed that Pulchrana baramica is a monophyletic group and nested within a group together with P. glandulosa and P. laterimaculata. The monophyletic group of P. baramica consisted of four distinct lineages that molecularly showed interspecific genetic variation. Clade 1 represents the population of Sumatra and Borneo (Kalimantan), clade 2 comprises the population from Borneo (Sarawak), clade 3 consists of population from Java, and clade 4 represents the population from Sumatra. Further research is required with the addition of morphological and acoustic data as supportive evidence to obtain more extensive comprehension of species identification.

The fanged frog, Limnonectes kuhlii, exemplifies the complexity of cryptic species. Though originally described from Java, subsequent studies indicate that L. kuhlii encompasses multiple lineages, suggesting the presence of several undescribed species. Suspecting the existence of multiple undescribed species within the L. kuhlii complex in Sumatra, we collected 17 specimens from Java and Sumatra. We extracted the 12S, tRNAval, and 16S mitochondrial DNA from these specimens for phylogenetic analysis using Maximum Likelihood and Bayesian Inference methods and for estimating time divergence. Our findings uncovered two novel diversity within the L. kuhlii complex both in Sumatra and Java. Furthermore, our estimation of time divergence suggests that the diversification of L. kuhlii in Java and Sumatra was influenced by geological and climatic events, including landmass emergence and sea-level fluctuations. In conclusion, our research provides critical insights into the evolutionary complexity and diversity of the L. kuhlii complex in Sumatra and Java. While our molecular evidence suggests novel diversity, further comprehensive morphological studies are imperative to confirm and describe these potential new species. Furthermore, additional sampling across its range and deeper investigations integrating both molecular and morphological data are crucial. Keywords: fanged frogs, Limnonectes kuhlii, Limnonectes sisikdagu, phylogenetics.
