Paul L.Th. Beuk Version date: 01-01-2002 00:00

Diagnosis. Small to medium-sized (6.0-8.0 mm) fungus gnats. Head and eyes small; antennae occasionally with long hairs; mouthparts not elongated. Thorax hump-backed, small. Wing membrane clear (Symmerus ) or with cross-band (Ditomyia ), Sc ending free, M connected with C by cross-vein just basal of cross-vein r-m; radial sector with three branches. Abdomen long and narrow.

Biology. Larvae live either in ligneous Polyporaceae (bracket fungi) or in dead but unrotten wood. Adults are mainly found in forested areas where they can be swept in low vegetation or collected in Malaise traps.

General references. Hutson et al. (1980 [keys]), Mamaev & Krivosheina (1988a [catalogue]), Vockeroth (1981 [general, key to genera]).
