Belongs within: Tipulidae.
Contains: Limnophila, Chioneini.

The Limnophilini are a group of crane flies with glabrous eyes and tibial spurs. Members of the genus Hexatoma have at most ten antennomeres though the antenna overall may be greatly elongated (Alexander & Byers 1981).

Characters (from Alexander & Byers 1981, as Hexatomini): Eyes glabrous. Terminal segment of palpus short; nasus absent. Tibial spurs present. Wings, if present, with Sc1 complete, free tip of Sc2 absent, tip of R1+2 present, R4 and R5 separate, CuA straight.
