55. Family NERIIDAE

By Brian R. Pitkin

Members of the Neriidae are long-legged flies closely related to the Micropezidae, of which they were once considered a subfamily. There are about 100 species in 20 genera distributed mainly in tropical regions. Only 22 species in 6 genera are recorded from the Australasian/Oceanian Regions.

Relatively little is known about their biology, but it is likely that the larvae of most species are saprophagous and feed on decaying vegetable matter (Olsen & Ryckman 1963, Ryckman & Olsen 1963). Telostylinus lineolatus has been described from larvae found in and under decaying bark on papaya trees (Carica papaya) in Asia (Berg 1947) and has been observed in the stems of the elephant bush (Portulacaria afra) in Hawaii (J.M. Tenorio, pers. comm.).

The Neriidae have been variously divided into subfamilies and tribes (e.g., Enderlein, 1922b; Hennig, 1937; Aczél, 1954). However, none of the proposed systems is very natural, hence a suprageneric classification has not been adopted here.
