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

We found an active nest of endangered Brown-cheeked Bulbul (Alophoixus bres) with two chicks in nest-adoption program at Jatimulyo village, Yogyakarta province, Indonesia on 19 December 2021. It was placed on the lateral branch of apus bamboo (Gigantochloa apus) 1.5 m high. The nest was cup-shaped, with outer diameter of ± 8 cm, inner diameter of ± 6 cm, and depth of ± 3 cm. It was made of living non-vascular plants and plant fragments. Our observation revealed that the food of the chicks was primarily comprised of insects (in the morning) and fruits (at midday). The insect preys include caterpillars, Lepidoptera, Coleoptera, Orthoptera and Diptera. The fruits were mangir, lempeni, and senggani.

Abstract

The systematics and distribution of the family Pupinidae (Gastropoda: Cyclophoroidea) in Java is reviewed. The family is represented in Java by four species of the genus Pupina, P. bipalatalis, P. compacta, P. junghuhni, and P. treubi. The shells of the species are described and figured, and the distribution data of the species are summarized. We have synonymized Pupina verbeeki Möllendorff, 1897 with Pupina treubi Boettger, 1890. All of the species except P. treubi, which is also known from Sumatra, are endemic to Java. Most previous records of Pupina from Java were from the western part of the island. Our new records show that the Pupina species are also more widespread in the drier central and eastern parts of Java. Their conservation status is therefore Least Concern.

Abstract

Odonata is important as environmental bioindicator as well as pest control. Langsa Urban Forest (LUF) is a 10-ha green open space in Langsa City, Aceh Province which serves the purpose of tourism and support biodiversity conservation, in which Odonata (dragonflies and damselflies) is included. Thereis a lack of Odonata research in Langsa, especially at the LUF area, therefore this study offers a baseline information for wildlife management. Field observations had been conducted between February to March 2022 using line-transect method. As a result, this study recorded 19 Odonata species from four families, of which Orthetrum sabina (Libellulidae) became the most prominent species observed. Odonata diversity in LUF was medium (H’ = 1.863-2.252) with population of each species presumed to be nearly even (J = 0.71-0.79). Odonata diversity in LUF serves as additional information on Odonata species found in Indonesia, especially Aceh Province. Also, the medium category of Odonata diversity index in LUF can be used as a reference for LUF management to support more ecosystems as Odonata habitat.

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

A fauna expedition has been conducted in Padang Bindu Karst, South Sumatra in 2021. Among the collected samples, a total of 111 specimens of Opisthostoma platycephalum (Caenogastropoda: Diplommatinidae) were collected from five sampling plots. This discovery is the first record of the land snail species in the southern of Sumatra island, as previous research only recognized its presence in Aceh, North Sumatra, and Peninsular Malaysia. This discovery contributes to the understanding of the biodiversity of South Sumatran land snails and highlights the importance of protecting limestone habitats.

Abstract

Meru Betiri National Park (MBNP) is one of the conservation areas as a habitat for diurnal raptors in East Java. However, the updated information on diurnal raptors in MBNP is still limited, with the latest information recorded in 2014. Therefore, this study aims to inventory the species composition of diurnal raptors in Bandealit Resort at MBNP. This research was conducted in April-June 2022 using the point count method with an observation radius of 1 km. We sampled a total of three observation points in three forest cover types i.e dense vegetation (primary forest), semi-dense vegetation (secondary forest-plantation), and low vegetation (coastal forest). Data collection included diurnal raptors species, frequency of encounters for each species, time of encounter, coordinate points, and activity (flyover, soaring, and perched). The results showed the presence of 10 diurnal raptors at the Bandealit Resort MBNP which consisted of two families (Accipitridae and Falconidae). Based on the IUCN Red list of threatened species, there are eight species of least concern (LC), one species of near threatened (NT), and one species of endangered (EN). The frequency of encounters shows that Crested Serpent-eagle (Spilornis cheela) has the highest frequency value (20%), while the Spotted Kestrel (Falco moluccensis) and Changeable Hawk-Eagle (Nisaetus cirrhatus) have the lowest frequency value (4%). Furthermore, as a special record, the Javan Hawk-eagle (N. bartelsi) is found with a fairly high frequency of encounters (11%). Approximately 75.71% of observed diurnal raptors are in soaring activity. Moreover, based on their distribution area, the primary forest has the highest composition of diurnal raptor species encountered.

Abstract

Idea blanchardii is one of many endemic butterfly species in Sulawesi, Indonesia. This species is among the highly traded butterfly species thus requires biological information on the captive breeding. The aim of this study was to obtain data on the adult life-span, to report the multivoltine generation, and to provide conservation-related insight. Captive breeding research on this species was conducted within the period of September 2018 until February 2020.  The host plant, Parsonsia alboflavescens, was used to support the life of this species for ovipositing and larval food plant. The adults would visit almost any flowers available at the facility. In total, 696 individuals were observed. Data on mating information of the species is presented here. Observations on when a female lays eggs are also revealed. This research showed that I. blanchardii is polygamous and polyandrous. Individuals of this species could live much longer than other butterfly species. A few could live over 80 days and one still seen laying eggs at the age of 136 days old.
