A new species of Cyrtodactylus is described from Lore-Lindu National Park, Sulawesi Island, Indonesia. 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. 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.
