A New Species of Bent-Toed Gecko Cyrtodactylus Gray, 1827, (Squamata: Gekkonidae) From the Island of Sulawesi, Indonesia

Based on three adult specimens, viz. two males and a female that form the type series, a new species of blind or worm-like lizards is described from Pulau (= Island) Manado Tua, a little volcanic island located off the northern tip of the Minahassa Peninsula of Sulawesi, Indonesia. Dibamus manadotuaensis sp. nov. differs from all congeneric species in the following unique combination of characters: maximum snout-vent length 135 mm; tail length up to 14.2 mm (i.e., 12–13% of SVL); labial and nasal sutures present and complete; four (three) postoculars; four to six scales on posterior edge of infralabial; 26–28 midbody scale rows; 30–33 transverse scale rows posterior to head; 25 transverse scale rows anterior to vent; 218–232 ventral scales; 39 subcaudal scales; relative size of frontal to frontonasal 0.68–0.73; relative size of interparietal to surrounding scales 0.67–1.43; 132–135 presacral and 21–24 postsacral vertebrae. Morphologically, D. manadotuaensis is most similar to D. celebensis, which occurs on mainland Sulawesi.Dibamus manadotuaensis sp. nov. represents the twenty-fourth species of Dibamus and the third species of this genus recorded from the Sulawesi region. At the same time, it is the only squamate species considered endemic for the islands of the Bunaken Marine National Park, to which Manado Tua belongs.

“…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.

“…Comparisons with Other Species. Although a number of species groups within Cyrtodactylus have been proposed on the basis of phenetic similarity (e.g., the louisiadensis complex, Kraus 2008) or geographic proximity (e.g., the Sundaland group, Hayden et al 2008), there exists no explicit phylogenetic hypothesis of relationships within the genus. Ongoing molecular phylogenetic work (Bauer et al, unpublished) suggests that certain geographic clusters of taxa and morphologically similar species do correspond to monophyletic groups within Cyrtodactylus.…”

A new cave-dwelling species of Cyrtodactylus Gray is described from Mae Hong Son Province in northern Thailand. The new species, C. erythrops sp. nov., is characterized by its moderate size (snout-vent length to at least 78 mm), relatively large, closely-spaced, flattened tubercles in 18-20 irregular rows at midbody, low number of ventral scales across midbody (28), absence of precloacal groove, presence of precloacal and femoral pores separated by a diastema, broad subcaudal plates, and dorsal pattern of dark spots and blotches. It is the fifth species of cave-dwelling Cyrtodactylus recorded from Thailand and its discovery adds to the mounting evidence that this genus exhibits unprecedented levels of localized endemism throughout tropical Southeast Asia.
