A new Potamanaxas(Hesperiidae: Pyrginae: Erynnini), patterned like P. bana, but with sickle-armed genitalia, not chicken claws.

Abstract


A new species of Potamanaxas is described from West Andes in Colombia. P. serp, sp. nov. is very similar to P. bana E. Bell, 1956 in wing patterns, but differs profoundly in male genitalia, which uniquely characterize it. This pair of superficially close species, one with extended, sickle-shaped cuculli and the other one with very short, vestigial cuculli apparently parallels the relationship in another Potamanaxas pair: P. perornatus Hayward, 1940 (extended) and P. andraemon (Mabille, 1898) (short). Comparative analysis of male genitalia and possible sympatry in Ecuador suggest that P. trigga Evans, 1953 new status, is a distinct biological species and not a subspecies of P. laoma (Hewitson, 1870) as originally proposed. Primary type specimens and their genitalia are illustrated for relevant taxa.

Una nueva especie de Potamanaxas se describe para la Cordillera Occidental en Colombia. P. serp, sp. nov. es muy similar a P. bana E. Bell, 1956 en patrones de ala, pero difiere profundamente en los genitales masculinos, que caracterizan de manera única. Este par de superficialmente especies cercanas, uno con cuculli extendida en forma de hoz y el otro con cuculli vestigial muy corto aparentemente es paralela a la relación en otro par Potamanaxas: P. perornatus Hayward, 1940 (extendida) y P. andraemon (Mabille, 1898) (corto). Análisis comparativo de los genitales masculinos y posible simpatría en Ecuador indican que P. trigga Evans, 1953 nuevo estatus, es una especie biológica distinta y no una subespecie de P. laoma (Hewitson, 1870) según la propuesta original. Espécimenes tipo primarios y sus genitales están ilustrados para los taxones relevantes.
