It is distinguished from all other Cyrtodactylus by a unique suite of scalation characters and a distinctive color pattern. The new species is the fourth Cyrtodactylus known from the island of Sulawesi and one of two new species found in 2004. These recent discoveries suggest that the diversity of the herpetofauna in Wallacea, a poorly studied biological ‘‘hotspot,’’ may be far richer than previously thought. Key words: Cyrtodactylus; Gekkonidae; Indonesia; Lore-Lindu National Park; New species; Southeast Asia; Squamata; Sulawesi THE GENUS Cyrtodactylus contains 95 de- scribed species distributed throughout the Indo-Australian Archipelago westward to In- dia (Bauer and Henle, 1994). Although many species recently have been reassigned to other genera such as Tenuidactylus, Cyrtopodion, Nactus, and Geckoella (Golubev and Szczer- bak, 1985; Kluge, 1983, 1991, 1993, 2001; Macey et al., 2000; Szczerbak and Golubev, 1984, 1986), the number of species currently or formerly in this genus continues to grow. New species have been recently described from Myanmar (Bauer, 2002, 2003), Sri Lanka (Batuwita and Bahir, 2005), Malaysia (Gris- mer, 2005; Grismer and Leong, 2005; You- mans and Grismer, 2006), Thailand (Bauer et al., 2002, 2003; Pauwels et al., 2004), Vietnam (Heidrich et al., 2007; Orlov et al., 2007; Quang et al., 2007; Ziegler et al., 2002), and southern Laos (David et al., 2004). For the island of Sulawesi, Boulenger (1897) and de Rooij (1915) listed three species of Cyrtodactylus: C. fumosus, C. jellesmae, and C. marmoratus. Based on overlap in pore characters, Brongersma (1934) synonomized C. fumosus with C. marmoratus thereby reducing the number of species on the island to two. Hayden et al. (2008) recently de- scribed a third species of Cyrtodactylus from the southwestern peninsula of Sulawesi. Herein we describe a fourth species of Cyrtodactylus from Sulawesi that differs dramatically from all known congeners. MATERIALS AND METHODS A herpetological biotic survey was conduct- ed on Sulawesi between September and December 2004. Specimens were tissued, preserved in 10% buffered formalin and transferred to 70% ethanol approximately two months later. The following measure- ments (after Bauer, 2002) were made on preserved specimens with dial calipers to the nearest 0.1 mm: snout–vent length (SVL); trunk length (TrunkL); crus length (CrusL); tail length (TailL); tail width (TailW); head length (HL); head width (HW); head height (HH); ear length (EarL); forearm length (ForeaL); orbit diameter (OrbD); nares to eye distance (NarEye); eye to ear distance (EyeEar); internarial distance (Internar); in- terorbital distance (InterOrb). Bauer’s (2002) snout to eye distance (SnEye) is referred to as rostrum length (RostL) to reflect the pre- ferred definition of rostrum as the portion of the head anterior to the orbit. In contrast, snout length (SnL) is defined as the portion of the head anterior to the nares. Sex was determined by gonadal inspection and scoring of prominent secondary sexual 6 CORRESPONDENCE: e-mail, cwlinkem@ku.edu Herpetologica, 64(2), 2008, 224–234 E 2008 by The Herpetologists’ League, Inc. 224
