Cylindrotomidae is a small family of tipuloids consisting of about 70 described
extant species. They share many characteristics with tipulids and limoniids.
Among extant forms, immatures live among mosses and herbaceous plants (not
in a substrate as in tipulids and limoniids) where they are phytophagous.
Adults of extant forms are found in marshy habitats. The group is treated
here as a family following treatment by contemporary European authors. The
family Cylindtrotomidae as used herein is equivalent to the subfamily Cylindrotominae
of other authors.
There are 13 species of fossil cylindrotomids. Most are found in various
Tertiary strata. Krzeminski (1993b) removed the genus Stibadocerites
Zeuner to the Limoniidae as a junior synonym of Dicranoptycha Osten
Sacken and stated that its geological horizon, described by Zeuner (1941)
as originating from the Lower Eocene of Scotland, was actually Upper Cretaceous
in origin.
