Canthyloscelidae
Template:Short description Template:Automatic taxobox
The Canthyloscelidae are a small family of midges closely related to the Scatopsidae.
Adults are small to medium-sized (2.5-9.0 mm) flies, relatively stout, usually dark coloured Nematocera with stout legs. They are associated with ancient woodland. Larvae are xylosaprophagous and live in the moist, rotting wood of stumps and fallen trees.[1]
Most are considered endangered due to the vulnerability of their habitat.
Fifteen described species live in New Zealand, North America, South America, Japan and Russia, and one is known from the Jurassic fossil record.
Systematics
Originally considered to be two separate families, the Synneuridae and the Canthyloscelidae. Haenni [2] placed the Synneuridae as the subfamily Synneurinae. A phylogenetic reclassification by Amorim [3] has reduced the Synneurinae into a synonymy of Canthyloscelinae.
