Abstract

The Indonesian archipelago is an ideal setting for the study of speciation and biogeography. This archipelago is divided into three island groups based on zoogeography: Sundaland, Wallaceaand the Australian region. In this paper we used frogs in genus Fejervarya (Bolkay) to study biogeography and examine patterns of gene flow across proposed zoogeographic boundaries. Severalmolecular studies on Fejervarya species from Indonesia have been carried out, but comparative studies among members of the genus Fejervarya have yet to be performed. In order to elucidate genetic divergence and geographic distribution of these frogs, we conducted a molecular analysis of the mitochondrial 16S rRNA gene using 179 frogs from five Fejervarya species. In total we collected from 32 localities in Sumatra, Kalimantan (Indonesian part of Borneo), Java, Bali, Sulawesi and Lesser Sunda Islands in Indonesia. Molecular phylogenetic analysis recovered 35 haplotypes and showed that frogs in the genus Fejervarya were divided into two well-supported clades. The first group were of three species, F. limnocharis, F. iskandari and F. cf. verruculosa and the other group clade consisted of Fejervarya cancrivora and Fejervarya sp. (Sulawesi-type). The average sequence divergence among these four species ranged from 1.09 to 16.03% (mean = 11.29±2.83%). The present results clearly show that there are five Fejervarya species in the Indonesian archipelago. Fejervarya limnocharis and F. cancrivora are widely distributed and sympatric in Sumatra, Borneo and Java. Fejervarya iskandari is not endemic to Java and also occurs in the Lesser Sundas. Fejervarya cf. verruculosa and Fejervarya sp. (Sulawesi-type) are endemic to Lesser Sunda and Sulawesi Island, respectively. Key words: Fejervarya, genetic divergence, geographic distribution, 16S rRNA gene

Abstract

By examining mitochondrial DNA phylogeny using 2424bp of sequence data 12S rRNA, tRNAval, and 16S rRNA genes, we evaluated the taxonomic relationships among Javan litter frogs Leptobrachium hasseltii from southern Sumatra, Java, and Bali. Leptobrachium hasseltii formed a well-supported monophyletic group, which comprised two major clades. One major clade represented the southern Sumatran and Javan populations and the other consisted of the population from Bali. The Javan and southern Sumatran clade included two subclades: the West Javan-southern Sumatran group and the Central Javan group. The genetic divergence between the two major clades (Bali vs. Java-Sumatra) suggested their separation happen at species level. Further studies using morphological and acoustic data are needed to determine the taxonomic status of Bali population.

Abstract

Asian grass frog Fejervarya limnocharis is being utilized as pets, for laboratory experiments, for a mixture of traditional medicine and for cuisine. The harvest of F. limnocharis in high volume can threat its population. Biological data such as the age when the specimens are harvested is valuable information to manage the harvesting system in sustainable way. We conducted the skeletochronology technique using paraffin methods and hematoxylin staining from 69 samples (46 males, 21 females, 2 juveniles). The results showed that the age harvested male ranged from 1 to 3 years old, while the female ranged from 2 to 3 years old. The snout-vent length (SVL) of harvested specimens ranges between 39.84−52.37 mm for both sexes. We propose an intervention in the harvesting system by limitation of the size for harvested specimens to at least 46 mm. In this minimum size, individuals of F. limnocharis have reproduced several times and have contributed to the  population in the wild.

Abstract

A new species of frog in the genus Microhyla is described from Sumatra, Indonesia based on molecular and morphological characters. This new species was previously confused with M. achatina, a Javan endemic. This new species is diagnosable from its congeners by possessing a medium size (SVL in adult males 18.20–21.32 mm, in adult females 20.37–25.51 mm), a stout body, a nostril–eyelid length being about half of the snout length, having a single outer palmar tubercle, a tibiotarsal articulation reaching the center of the eye (when the hindlimbs are stretched and adpressed to the body), having finger and toe tips dilated, having the dorsum with medial longitudinal grooves, and excibiting a very thin and short dark stripe on the temporal region above a wider cream stripe, extending from the postorbital area to insertion of forelimb. Additionally, the new species is characterized by possessing relatively little foot webbing. Uncorrected 16S rRNA sequence divergences between the new taxon and sequences for other congeneric species available ranged from 4.8 to 15.0%.

Abstract

Kurixalus absconditus sp. nov., a new species of tree frog of the genus Kurixalus, described from West Kalimantan on the basis of molecular phylogenetic and morphological evidence. The new species can be distinguished from its congeners by a combination of following morphological characters: having smaller body size, more prominent of mandibular symphysis, skin smooth on throat, vomerine odontophores two oblique series touching anterior corner of choanae and widely separated, vomerine teeth thick, buccal cavity narrow and deep, choanae with teardrop shaped, single vocal slit, weakly crenulated dermal fringe on fore- and hindlimbs.

Abstract

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.

Abstract

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.

Abstract

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.
