Perisama tryphena subsp. affinis Attal & Crosson-du-Cormier 1995

Perisama tryphena affinis Attal & Crosson-du-Cormier, 1995, stat. rev. Perisama tryphena is one of the most common species of the genus Perisama, characterised by a wide distribution, and important individual and geographic variation (Fig. 7), similar to that observed in P. bomplandii. Perisama goeringi was described as a separate species by Druce (1875) from the Venezuelan Cordillera de Mérida. Perisama affinis was described by Attal & Crosson-du-Cormier (1996) from the Department of Huánuco in Peru. Both, P. goeringi and P. affinis were regarded as subspecies of P. tryphena by Lamas (2004), and were reinstated as species by Attal and Crosson-du-Cormier (2010). Comparative analysis has shown no significant differences in male genitalia morphology (Fig. 8) of the three taxa, and molecular data also confirm they are closely related, with genetic distance varying from 0.3-1.2%. Since there is also no evidence of the three taxa being sympatric, P. affinis and P. goeringi are henceforth considered as subspecies of P. tryphena.
