Diagnosis. Small (3.0-4.5 mm), delicate fungus gnats with yellowish body. Head and eyes small; mouthparts not elongated. Thorax hump-backed and small; wings delicate and without markings; Sc ending in C, cross-veins r-m and bm-cu contiguous; base of M vestigial; radial sector with two branches. Legs sometimes with swollen segments in the female fore tarsus. Abdomen narrow.
Biology. Larvae are fungivorous (association with Peniophora reported) but are also found under rotting logs, probably feeding on mycelium. The larvae build mucous tubes on the logs and form a kind of cocoon for pupation.
