Casilla 70005. Santiago, Chile. OTES N Abstract: Liolaemus pseudolemniscatus (Lamborot and Ortiz 1990) is a poorly known species. Two specimens were collected in “Cerro Provincia”, central Chile, expanding in 136 km (straight line) its latitudinal distribution and in 800 m its altitudinal distribution. This record adds a new species of Liolaemus lizard for the “Región Metropolitana”, Chile. The genus Liolaemus (Wiegmann 1834) comprises band, which is yellowish-brown in L. lemniscatus (Figure a total of 223 species of wide distribution from the high 2). Moreover, L. pseudolemniscatus has a higher number Andes of central Perú to “Tierra del Fuego”, and from sea of chromosomes (2n = 44) than L. lemniscatus (2n = 34) et al. 2010). In Chile at (Lamborot and Ortiz 1990). least 88 species have been registered (Vidal et al. 2008). Liolaemus pseudolemniscatus is distributed from the levelLiolaemus to more thanpseudolemniscatus 5000 m (Lobo (Lamborot and Ortiz 1990) belongs to the subgenus Liolaemus and the nigromaculatus surroundings of “Bahia Totoralillo” (30°04’ S, 71°22’ W) to “Hierro Viejo” (32°16’ S, 71°00’ W) in central Chile, body.
