Epipleoneura Williamson 1915

Figures 11 c, 21–23, 31–33, 38

Type species: Epipleoneura lamina Williamson 1915 by original designation.

Diagnosis. See under Drepanoneura .

Distribution. South America, within forests from Venezuela and the Guyanas south through Ecuador, E Peru, and Brazil to Bolivia, Paraguay, and NE Argentina.

Remarks. The erection of Drepanoneura and corresponding transfer of two species formerly placed in Epipleoneura leaves 24 names currently associated with the latter genus. Fraser (1946) described Protoneura protostictoides from Mishuyacu, Peru, based on an incomplete male lacking S9–10, and he diagnosed it from other neotropical protoneurids by wing venation, size, and color. Examination of the holotype of Protoneura protostictoides by RWG convinced him that it is an Epipleoneura by its overall size, color pattern, and genital ligula morphology, and he ( Garrison 1991: 29) suggested its synonymy with E. lamina . However, due to the speciose nature, poor knowledge of distributions, and high likelihood of new taxa within Epipleoneura we consider that it advisable to retain the name Epipleoneura protostictoides until further studies of material from the Mishuyacu region can be realized.

During August 1990, RWG and T.W. Donnelly collected a series of a small Epipleoneura in Bolívar State, Venezuela, which approaches E. capilliformis except for the shape of its sclerotized epiproct. This species, known only from a series of males, is described and compared with its sibling species E. capilliformis .
