Taxonomy

Within family Hesperiidae, Quasimellana is placed in tribe Hesperiini.[1]

The genus was erected in 1994 by John Burns, containing at the time of description three species groups and twenty-four species, five of which (Quasimellana andersoni, Q. antipazina, Q. imperfida, Q. mielkei and Q. siblinga) were first described in the same publication. The remaining nineteen species were previously described in different genera. Quasimellana mexicana, originally described as Atrytone mexicana, is the designated type species of the genus.[2]

Distribution

Distribution of the genus is from northern Argentina to the southern United States.[2] Fourteen species are known to occur in North America.[3]

Appearance

Male wingspan ranges from 11.4 to 17.9 mm, with most species averaging between 14 and 16 mm. Females are on average larger than males of the same species. The eulogius group, with exception of Q. mulleri, shows strong sexual dimorphism, while such dimorphism is highly variable from species to species within the sethos and nicomedes groups.[2] The dorsal side of males of group eulogius is always yellow-orange with brown-black and dark venation.[2]
