Abstract

PORTHIDIUM NASUTUM (Rainforest Hognosed Pitviper). ECUADOR: PROVINCIA DE MANABI: 11 km W of Bahía de Caráquez, on Chone - Sto. Domingo de Los Colorados Road (ca. 00°40’S, 80°23’W, 50 m elev.). 17 July 1991. H. Pedroban and E. Palacios. Laboratorio de Anfibios & Reptiles, Universidad San Francisco de Quito & Fund. G. Orcés (FHGO-USFQ 698). Verified by Jean-Marc Touzet. This species inhabits the humid lowlands of Middle America and adjacent northwestern South America from Chiapas (Mexico) southward to Pichincha (Ecuador) (Porras et al. 1981. Tulane Stud. Zool. Bot. 22:85-107, Schatti and Kramer 1993. Rev. Suisse Zool. 100[2]: 235-278). First province record and the southernmost for the species, extending the range ca. 130 km WSW from closest known localities (surroundings of Santo Domingo de Los Colorados, Pichincha Province, Porras et al., op. cit.). Schatti and Kramer (op. cit.) erroneously cited the species from Carchi Province based on specimens from “Paramba”; however this locality is in Imbabura Province (Lynch and Duellman 1997. Univ. Kansas Nat. Hist. Mus. Spec. Publ. 23: 1-236).
