The Papuan Chrysosoma lucigena group (Diptera: Dolichopodidae: Sciapodinae)

Abstract

The Chrysosoma lucigena species group is revised and comprises 13 species, all from New Guinea and immediately adjacent islands: C. lucigena (Walker) and C. splendidum (Wulp), and 11 newly described species: C. akrikense, C. baiyerense, C. betege, C. bitcoin, C. cuprevittatum, C. fumifemoratum, C. macalpinei, C. orokaindi, C. oromissim, C. tabubil, and C. watutense. The lucigena group comprises species with dark maculated wings, long setae on the femur and tibia of leg I, and metallic green and bronze thoracic coloration. The total loss of anterior dorsocentral setae in both sexes of the lucigena group is discussed in the context of a possible source for higher-level taxonomic characters in Diptera.
