Adding to the rich fauna of the Chocó region in Ecuador, a new species of Potamanaxas (Hesperiidae: Pyrginae: Erynnini).

N. V. Grishin


A new species of Potamanaxas is described from the Chocó region in northern Ecuador. Potamanaxas hermieri, sp. nov. is most similar to P. paralus (Godman & Salvin, 1895) and differs from it in the shape of the discal cream-colored band on wings and characters of the male genitalia. Furthermore, significant differences in male genitalia and facies suggest that P. cranda Evans, 1953 new status, and P. paphos Evans, 1953 new status are distinct species and not subspecies of P. thestia (Hewitson, 1870) and P. hirta (Weeks, 1901), respectively. The status of P. paralus as a species-level taxon is confirmed by the analysis of morphology. Lectotypes for Potamanax paralus and Leucochitonea thestia Hewitson, 1870 are designated to ensure nomenclatural stability.
