Camptopeltes, a new Neotropical genus of oscinelline Chloropidae (Diptera)

Camptopeltes n. gen. is described for three new species: Camptopeltes atratum n. sp. (type species of the genus; type locality Cartago. Costa Rica); Camptopeltes citrinum n. sp. (type locality Yacambo, Venezuela); and Camptopeltes nubilatum n. sp. (type locality Aragua, Venezuela). Camptopeltes is distinguished from other oscinelline genera on the combination of a strongly convex scutum, a trapezoidal scutellum that is deflected dorsally relative to the scutum, a reduced flexure in wing vein CuA(1), reduced cephalic bristling, reniform third antennal segment, and thin arista. Although its relationship to the rest of the Oscinellinae is unresolved, it may be closely related to the tribe Elachipterini.
