摘要

Previously undescribed characters are evaluated and incorporated in a redescription of the Nymphomyiidae (Diptera). The revised family includes seven species, two of which are new. Nymphomyia dolichopeza, new species, is widespread and locally abundant in streams of the southern Blue Ridge Mountains, primarily in North Carolina and Georgia, U.S.A.; and N. holoptica, new species, is recorded from Hong Kong. Based on structural and phylogenetic criteria, the monobasic genera Palaeodipteron Ideand Felicitomyia Kevan are new synonyms of Nymphomyia Tokunaga. Larval, pupal, and adult characters were used to reconstruct the phylogenetic and biogeographic relationships of world species of Nymphomyia. Based primarily on adult features, Nymphomyia is divided into two species groups with the following phylogenetic relationship: (1) alba group (alba+(levanidovae+ rohdendorfi)); and (2) walked group ((walkeri + dolichopeza) + (brundini + holoptica)). Several compelling characters help define the eastern Palaearctic alba group, and others provide strong evidence that the Oriental species brundini and holoptica are monophyletic. Although data suggest that the Nearctic fauna (walkeri and dolichopeza) is monophyletic, the cladisticbasis for this hypothesis is relatively weak (two reductive characters). Keys to larvae, pupae, and adults and a discussion of collection techniques, ecological data, and distributions are provided.
