RES Handbook Vol 9 Part 2 ii. Diptera - 2. Nematocera: families Tipulidae to Chironomidae (Trichoceridae - Culicidae)

THis is a small family represented in Europe by two genera, Trichocera (winter gnats) and Diazosma. The wing venation is similar to that of some TIPULIDAE (LIMONIINAE), but the larva much more closely resembles that of the ANISOPODIDAE (RHYPHIDAE) and prevents their inclusion in the TIPULIDAE. It is now usual to treat them as forming a separate family allied both to the TIPULIDAE and to the ANISOPODIDAE.
