A New Species of Bent-Toe Gecko (Gekkonidae: Cyrtodactylus) from Sulawesi Island, Eastern Indonesia

530

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.

“…In their diagnosis and Table 1, Linkem et al (2008) listed 12-13 precloacal pores for C. spinosus, whereas in their Table 2 they listed only 8-12 precloacal pores. In their Table 1, these authors also listed precloacal pores for individual females, although females are described as lacking pores in their variation section.…”

Historical considerations and comments on the type series of Cyrtodactylus marmoratus Gray, 1831, with an updated comparative table for the bent-toed geckos of the Sunda Islands and Sulawesi

Cyrtodactylus marmoratus Gray, 1831, a species of bent-toed gecko exhibiting a precloacal groove in males, was described on the basis of specimens collected by Heinrich Kuhl and Johan Conrad van Hasselt in Java, Greater Sunda Islands, Indonesia. Kluge (1985) subsequently designated a lectotype for C. marmoratus from a series of these specimens (i.e., syntypes), now housed in the herpetological collection at Naturalis (formerly the Rijksmuseum van Natuurlijke Historie; RMNH), Leiden, the Netherlands. Our work at Naturalis shows that the type series of C. marmoratus at RMNH actually comprises two sets of specimens, and that examination of specimens from one set or the other by different authors, including Kluge (1985), is responsible for some confusion surrounding the type series of this species. As a consequence, we present relevant morphological data for all 14 specimens constituting the type series of C. marmoratus at RMNH for the first time. The type status of two specimens of C. marmoratus in the collection at the Muséum National d'Histoire Naturelle, Paris, France, remains unresolved at present. Owing to the inconsistent naming and application of terms for some key characters (e.g., groove, sulcus, pit, hollow, depression) used in the diagnoses of Cyrtodactylus species, we here propose a set of novel and useful definitions that are supported by photographs. We also illustrate the sexually dimorphic expression of this character in C. marmoratus. Finally, we present a revised comparative table for the bent-toad geckos of the Sunda Islands and Sulawesi.

“…Although highly artificial, we have employed commonly used and easily scorable single differential characters for this purpose. Recent summaries of some of these, and other, features for large numbers of Cyrtodactylus species have been provided by Youmans & Grismer (2006), Grismer et al (2007), Grismer & Ahmad (2008), Linkem et al (2008), and Rösler & Glaw (2008).…”

“…Its approximately 100 described species are distributed across tropical Asia from India and Sri Lanka to the Philippines, northeastern Australia, New Guinea, and the Solomon Islands (Rösler 2000;Kluge 2001;Bauer 2002Bauer , 2003Bauer et al 2002Bauer et al , 2003Günther & Rösler 2003). New species of Cyrtodactylus continue to be discovered throughout the range of the genus (e.g., Sri Lanka, Batuwita & Bahir 2005;Indonesia, Hayden et al 2008;Linkem et al 2008;New Guinea and the Solomons, Rösler 2001;Günther & Rösler 2003;Kraus & Allison 2006;Oliver et al 2008;Rösler et al 2007;Kraus 2007Kraus , 2008, but the greatest rate of discovery has been in Southeast Asia.…”

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.
