new municipality record and the westernmost distribution of the species on the Pacific Coast of Mexico.

The Collard Dwarf Gecko, Sphaerodactylus glaucus score (EVS): twelve] for Mexico, based on geographic is found from Veracruz and Oaxaca, Mexico, through the distribution, ecological distribution, and degree of Yucatan Peninsula and northern Guatemala to western Honduras (Taylor 1947; Smith and Taylor 1966; Harris and protection laws rate S. glaucus Kluge 1984; Köhler 2008). This species has been reported human persecution. Additionally, Mexican environmental from several different vegetation types, including tropical as Subject to Special wet forest, tropical moist forest, tropical dry forest, UniversidadProtection (Pr) del Mar (NOM-059-2010; [FCHU062]) of SEMARNAT the specimen 2010). is tropical very dry forest, and subtropical moist forest, at depositedA photographic in the photographic voucher (Fotocolectacollection of the Herpetofauna Universidad elevations ranging from sea level to 1000 m (Wilson and del Mar campus Puerto Escondido.

On 25 June 2009 at 08:45 am, an adult S. captured, photographed, and released under permit glaucus was found in Parque Nacional Lagunas de Chacahua, Cerro (Figure 1- verified by Aurelio Ramírez-Bautista) denumber Vida Silvestre.
