ResumoFour species of anguids are found in northcentral Mexico: Barisia imbricata, Gerrhonotus infernalis, Gerrhonotus lugoi, and Elgaria parva. Of these species, 2 are relatively rare and have only been recorded from isolated localities. Gerrhonotus lugoi is endemic to the Cuatro Ci&negas Basin in Coahuila (McCoy, 1970). Elgaria parva is known from only 2 specimens collected just south of Galeana, Nuevo Leon (Knight and Scudday, 1985). Herein we describe a new record of E. parva from ca. 65 air-km north of the type locality. On 31 May 2001 we collected a single specimen of E. parva in a canyon bottom west of San Isidro, Municipio Santiago, Nuevo Le6n, Mexico. The canyon (ca. 1,600 m elevation) runs east to west, is characterized by steep limestone walls covered with various agaves (Agave), sotol (Dasylirion), and scrub oak ( Quercus), and has intermittent pools of water. The canyon bottom has piles of leaf litter and large rocks scattered throughout. The specimen was found crawling along the base of the canyon wall at 1630 h.
