Abstract

The Neotropical genus Goniaspis Duda is revised. The genus includes ten species: G. equalis (Williston) (type locality: Saint Vincent); G. lucia sp. n. (type locality: Saint Lucia); G. lurida sp. n. (type locality: Blue Creek, Belize); G. obscurata Duda (type locality: San José, Costa Rica); G. opaca sp. n. (type locality: San José, Costa Rica); G. rubra (Becker) (type species of genus, type locality: Sierra san Lorenzo, Colombia); G. scutellaris (Williston) (type locality: Saint Vincent); G. subaequalis (Malloch) (type locality: Montserrat, Trinidad); G. truncata (Malloch) (type locality: Trece Aguas, Guatemala); and G. versicolor sp. n. (type locality: La Paz, Bolivia). The identity of G. peruana Duda cannot be determined and it is considered a species inquirenda. All recognized species are described and illustrated, and a key to species is included. Goniaspis has been assigned to the Hippelates genus group (or tribe Hippelatini) in previous higher classifications of the Chloropidae, based primarily on the possession of a strong, ventral, hind-tibial spur. However, this character state is subject to frequent homoplasy in the Chloropidae, and multiple morphological character states suggest that Goniaspis may be more closely related to the genus Elachiptera Macquart.
