Abstract

A new species of toad, Bufo chavin, is described from two localities (3010 and 3070 m) from the eastern Andean slopes of central Peru (Departamento de Huánuco, Provincia de Pachitéa, Distrito de Chaglla) where it occurs sympatrically with Bufo spinulosus. Bufo chavin is referred to the Bufo veraguensis group. The new species differs from all members of this group by having large, elevated, elongate glands on each forearm and tibia, two large, elevated, elongate glands on the outer dorsal margin of each foot and one small, elevated gland on the outer dorsal margin of each hand. Eggs are relatively large, yolky and unpigmented in the new species.

Se describe una nueva especie de sapo, Bufo chavin, procedente de dos localidades (3010 y 3070 m) en la vertiente oriental de los Andes del Perú central (Departamento de Huánuco, Provincia de Pachitéa, Distrito de Chaglla) donde se presenta simpátricamente con Bufo spinulosus. Bufo chavin es incluido al grupo Bufo veraguensis. La especie nueva difiere de todos los miembros de este grupo por tener una glándula larga, elevada y elongada en cada antebrazo y tibia; dos glándulas grandes, elevadas y elongadas en el margen dorsal externo de cada pie; y una glándula pequeña elevada en el margen dorsal externo de cada mano. En la especie nueva, los huevos son relativamente grandes, presentan abundante yema y no están pigmentados.
