Occurrence of Pseudoboa nigra (Duméril, Bibron & Duméril, 1854) in Argentina (Serpentes: Dipsadidae)

Abstract

The genus Pseudoboa is composed by six species of snakes widely distributed in most of South America, western Panama, and the Tobago and Grenada islands. Due to lack of voucher material, Pseudoboa nigra was excluded from the snakes species lists from Argentina. Here, its presence is confirmed, increasing to 128 the snake species number known for this country.
