“…These birds were discovered in Peleng Island, then this will greatly open an opportunity for the discovery of new species from other vertebrates, such as amphibians and reptiles. The reptile fauna of Sulawesi is one of the least known in Southeast Asia (Amarasinghe et al 2015). According to Koch (2012), about 60% of the known snake fauna from Sulawesi is endemic, although this is likely to be underestimated.…”

Abstract. Riyanto A, Rahmadi C. 2021. Amphibian and reptile diversity of Peleng Island, Banggai Kepulauan, Central Sulawesi, Indonesia. Biodiversitas 22: 2930-2939. Indonesia is an archipelagic country and is known as one of the world’s megadiverse countries and has three zoogeographic zones. Therefore, proper conservation efforts to face extinction threats are very important, and the fundamental steps to better understanding it’s biodiversity provide valuable baseline information. Amphibians and reptiles (herpetofauna) are main biodiversity components that experience extinction threats but, at the same time, provide an important role in ecosystems and community life. This paper is the first to provide a checklist of the herpetofauna of Peleng Island, Banggai Kepulauan, Central Sulawesi, Indonesia. Data was gathered by field surveys and supplemented by references. Visual Encounter Surveys (VES) were undertaken in 8 sites. A total of 34 species are listed herein, 29 (85%) of them revealed from this fieldwork, and 21 (62%) new for the island. At least two candidate new species of the genus Cyrtodactylus were confirmed by molecular data and one frog of the genus Kaloula also suspected new species.

“…nov. underscores the underestimated herpetological diversity on the island of Sulawesi (Koch 2011). Several have predicted that numbers of species will dramatically increase due in part to discovery of cryptic species and the exploration of under-surveyed regions (Iskandar & Tjan 1996;Brown et al 2000;Evans et al 2003a,b;Linken et al 2008;Hayden et al 2008;Amarasinghe et al 2015). South East Sulawesi remains one of the island's least biologically explored areas and still contains some of the most intact forest systems found on the island.…”

We describe Cyrtodactylus hitchi sp. nov., a new species of Bent-toed Gecko from montane forests in the Mekongga Mountains, South East Sulawesi, Indonesia. Although we cannot speculate about relationships, morphologically it shares several traits with C. batik, a large species known only from Mount Tompotika near the tip of Sulawesi's Eastern Peninsula. The following unique combination of characters distinguishes it from all other congeners: absence of precloacal groove, absence of precloacal and femoral pores, absence of enlarged femoral scales, no abrupt contact between large and small postfemoral scales, 18-20 lamellae under the fourth toes, and transversely enlarged, median subcaudal scales arranged in a single row.

“…For comparisons, we examined specimens of Philippine snake species represented in the University of Kansas Biodiversity Institute herpetological collections (KU). For snake species not represented in this collection (and, in general, poorly represented in U.S. collections), we relied on published species accounts (Taylor, 1922;Inger and Marx, 1965;Wallach, 1988;Brown et al, 1999;David and Pauwels, 2004;Grismer et al, 2004;Ziegler and Quyet, 2005;Howard and Gillespie, 2007;Koch et al, 2009;Orlov, 2009;Nguyen et al, 2009;Orlov et al, 2010;Amarasinghe et al, 2015;Yang and Zheng, 2018).…”

“…Calamaria alcalai can be distinguished from all species outside of the genus Calamaria by having the internasals and prefrontals fused (versus distinct). Additionally, C. alcalai can be distinguished from species of Hemibungarus by having the supralabials broadly in contact with the prefrontal and parietal (versus not in contact), and by having 13 longitudinal rows of dorsal scales (vs. 15); from species of Oxyrhabdium and Myersophis by having the loreal and anterior temporal scales absent (vs. present), and by having 13 longitudinal rows of dorsal scales (vs. 15); from species of Naja by having the supralabials broadly in contact with the prefrontal and parietal (versus not in contact), and by having 13 longitudinal rows of dorsal scales throughout the length of the body (vs. 21-23 rows behind the head, reducing to 13-15 rows before the vent); from species of Calliophis by having the supralabials broadly in contact with the prefrontal and parietal (versus not in contact); from Levitonius mirus by having subcaudals paired (vs. unpaired) and other characters (Weinell et al, 2020); and from species of Calamorhabdium, Collorhabdium, Etheridgeum, Macrocalamus, Pseudorabdion, and Rabdion by having 13 longitudinal rows of dorsal scales (vs. 15;Inger and Marx, 1965;Wallach, 1988;David and Pauwels, 2004;Amarasinghe et al, 2015). The new species is known only from the Philippine island of Mindoro, whereas Calamorhabdium, Rabdion, Collorhabdium, Etheridgeum, and Macrocalamus are not known from the Philippines; Calliophis, Myersophis, Pseudorabdion, and Levitonius mirus occur in the Philippines, but have not yet been recorded on the island of Mindoro (Leviton et al, 2018;Weinell et al, 2020).…”

A new species of reed snake, genus Calamaria (Colubridae: Calamariinae), from Mindoro Island, Philippines

We describe a new species of reed snake of the genus Calamaria Boie 1827, from Mindoro Island, Philippines. The new species differs from all other species of Calamaria by having the following combination of characters: a high number of subcaudal scale pairs (> 40 in males, > 30 females) and ventrals + subcaudals (> 205 in males, > 210 in females); mental scale not contacting chin shields; dorsal surface of head, body, and tail uniformly dark brown; and ventral surface of body (extending to include part or all of first longitudinal row of dorsals) uniformly pale (yellow or white in life). The new species is likely most closely related to Calamaria schlegeli Duméril, Bibron, and Duméril 1854, which also has a high number of subcaudal scales compared to other Calamaria species. The new species is the second Calamaria species known from Mindoro Island and the eighth known from the Philippines, and its presumed distant relationship from other Philippine Calamaria suggests an additional colonization of the Philippines by this genus from continental Asia.
