Abstract

The four species comprising the leucochrysine genus Berchmansus are reexamined. Two species [Berchmansus elegans (Guérin-Méneville, 1844), and Berchmansus brooksi Tauber, 2006] are transferred to the small genus Vieira. Redescriptions, with illustrations of the male and female genitalia, are provided for the two remaining species: Berchmansus adumbratus Navás, 1913b (the type species for the genus) and Berchmansus cinctipes (Banks, 1915). These two species express several unique features that support retaining Berchmansus as a separate genus within Leucochrysini. The type species of Vieira, Vieira leschenaulti (Navás, 1913a) is also redescribed, and the genus, which now contains four species, is reassigned to the tribe Belonopterygini. Finally, two additional, new species that would key to the genus Berchmansus are described. These species are very closely related, and they appear to belong within Leucochrysini; however, their generic affiliation is not readily apparent. For convenience, they are placed in the large, ill-defined genus Leucochrysa. A new lectotype and new paralectotypes are named for B. cinctipes.
