Lygistorrhinidae

Overview

The Lygistorrhinidae are a monogeneric family of about a dozen species of fungus gnats, belonging to the Mycetophiloidea, and putatively the sister group to the Mycetophilidae (sensu stricto).

Description

Adult Lygistorrhinidae are readily recognised by their elongate mouthparts which are many times the length of head, and by the very reduced wing venation with only two branches of the radius and CuA2 complete to the margin, and with the medial sector with two fragmentary branches and one almost complete branch.
