Abstract

Taxonomic studsy was made on the species of the family Corycaeidae recently collected from 8 sites in lndonesian waters. Twelve species, including 2 subgenus Corycaeus (C. speciosus Dana, 1849, C. crassiusculus Dana, 1849), 4 sllbgenlls Ditrichocorycaeus (c. andrewsi Farran, 1911, C. asiaticusDaM, 1894, C. erythraeus Cleue, 1901, C. lubbocki Giesbreclrt, 1892), 1 subgenus Monocorycaeus (C. robustus Giesbrecht, 1891), 2 subgenus Onychocorycaeus (C. catus Duhl, 1894, C. pacificus Dana, 1894), 1 subgenus Urocorycaeus (C. longistylis Dana, 1849), and 2 species of genus Farranula (F.concinna Dana, 1849, F. gibbula Giesbrect, 1892) were recorded.Descriptions, measurements, and figures are given for all species, along with a review of their distribution over tire world's oceans, witlr taxonotnical remarks, and restricted synonymies.

Abstract

The scales of Latimeria menadoensis has a variety of the shape of the scales from oval, rectangular, footprint, elongated-pointed edge etc. The comparison in the portion of the exposed and embedded part of the total length of the scales of Latimeria menadoensis and Latimeria chalurnnae at the approximately similar part of the body i.e. scale on the dorsal region and scales located on the region extending lateral posteriorly until caudal, indicated that this portion is different. In L. chalumnae the exposed part are one third and the embedded part are two third of the total length of the scale. The exposed part in the L. menadoensis are more than one third (average 35.9% of total length), while the embedded part are less than tioo third, but 011 the other part of the body i.e. dorsal lobe fin, the embedded part was 73.9% or approximately three [ourth of the total lellgth of tile scale. The 175 loose scales were also examined and discussed. Some of the loose scales ioere examined 1111del' the scanning electron microscope (SEM) by using two kinds of preparations. It showed the apex region, the annular ridges, the radiating ridges and the denticles.

Abstract

The phylogeny of Glyphodes Cuenee (14 species) and four outgroup species (Feltia jaculifera, Metallarcha aureodiscalis, Talanga sexpunctalis and Agrioghrypta eurytusalis) was inferred fromnucleotide sequence variation across a 686-bp region in the CO I gene. Over the entire 686-bp region, 19.9% sites were informative (3.35% in the 1st-, 0.29% in the 2nd - and 16.32% in 3rd - codon position). The results also showed that the base composition of this region was high A+T biased (C= 0.258) and the averages ofestimated sequence divergence in the comparisons between species within and between groups were 7.1% and 9.0%, respectively. In general, the phylogeny based on CO I gene by including all substitutions or any partial data set used in this study was not only able to recover almost the three monophyletic groups withinGlyphodes as previously recovered by morphological phylogeny but also showed more clearly the relationships among them: Glyphodes group 2 was branched off first then followed by group 3 and 1.

Abstract

Eiglit genera of lndo-Australian butterjiies: Algia. Algiachroa, Cirrochroa, Cupha, Phalanta, Terinos, Vagrans, and Vindula are presented here. These genera together with two Afrotropical genera: Lachnoptera and Smerina, and a Central American genlls Euptoieta were previollsly placed as subiribe uncertain.One-hundred adult morphological characters were scored for fifty-four taxa, and were analyzed simultaneousuj (Nixon and Carpenter, 1993). The cladistic analysis showed that all species were properly assigned to monophyletic genera, and the arrangement of the outgroup taxa is in concordance with the classification previously suggested. The eight lndo-Australian and two Afrotropical genera belong to the tribeVagrantini within the subfamily Heliconiinae.

Abstract

Bawean deer (Axis kuhlii) is an endangered Indonesian deer that is quite unique since its habitat is isolated and the species is endemic to the Bawean Island. Data on its biology is very limited. especially those related to antler's growth. Monitoring the antler's growth from the post weaning age (3-4 months) to 22 months old showed that, this process was related to the animal's reproductive physiology, starting at the age of six months, when the testes entered the scrotum. and a rapid body growth occured. At the age of 21 months, the animal had its first full hard antler's. The stag had its longest period of hard antler's at least for more than eight months. There seemed to be a close relation between the body growth cycles and theantler's growth. Hair molting lasted for 25-40 days. These results indicated that the period of physiological change in relation to antler's growth and some reproductive activities in the Bawean deer were within the cycle of other temperate and tropical deer species.

Abstract

The spotted winged bat (Balionycteris maculala) is recorded for the first time in Sumatra, Indonesia. The morphoiogy of 13 specimens from Sumatra was compared with that of specimens from Durian (Riau Archipelago) and Kalimantan-lndonesia. Univariate and multivariate analyses show that the Sumatran population is both significantly smaller in a number of characters and some differences in shape occur between Sumatran and Kalimantan specimens. The Sumatran population is similar in morphology to that of Durian Island. The Sumatran and Durian island specimens are referred to as Balionycteris maculata seimundi.

Abstract

Acrobates pygmeus is a small arboreal marsupial thought to be restricted to eastern Australia, from southeastern South Australia to the tip of Cape York Peninsula in northern Queensland. Here I discuss the possibility that the species also occurs in New Guinea, based on two poorly-localized museum specimens (in London and Stockholm) supposedly collected from that island.

Abstract

Knowledge of breeding by the Pied Stilt (Himantopus leucocephalus) and Javan Plover (Anarhynchus  javanicus) is limited. During fieldwork from 15 August to 10 November 2015 we studied nest features, hatching rate and clutch size of both species at the Wonorejo Fishpond in East Java, Indonesia. During the investigation 42 Pied Stilt nests and 27 Javan Plover nests were found. Pied Stilts build their nests in both mud and surrounded by water; the mud nests include a greater variety of components than nests on water. We provide the first description of the nest of Javan Plover nest on the ground and are made of wood, snail shells and shellfish. The Pied Stilt's clutch size is typically 2-4 eggs, while the Javan Plover's clutch size is often 2-3 eggs. The hatching rate of Javan Plover was 61.5%, and 75% in Pied Stilt with flooding the key factor influencing hatching rate.

Abstract

Genus Chirixalus is a group of small tree frogs within the family Rhacophoridae, distributed across Asia, including northeastern India, southern China, mainland Southeast Asia, and islands such as Sumatra and Java in Indonesia. Ongoing taxonomic research continues to uncover new species within this genus. With the assistance of citizen science, the discovery of new species and the documentation of species’ geographic distribution have been greatly supported, expanding our knowledge of biodiversity and conservation processes. In our study, we recorded the tree frog genus Chirixalus from Jatilawang District, Banyumas Regency, Central Java. Based on our examination of morphological traits and call characteristics, these specimens resemble Chirixalus trilaksonoi. This finding represents the first record extending the known distribution range of Chirixalus trilaksonoi into Central Java. Variation in dorsal morphology and vocal characteristics is the most notable difference observed in this study. This finding can assist field researchers, and citizen scientists particularly those working in taxonomy. Further research and intensive surveys are needed to evaluate its conservation status and enhance our understanding of its taxonomic classification.
