Skuse, 1888
Species Guides
1Heteropterna is a of predatory fungus gnats established by Skuse in 1888, containing at least 20 described . Members of this genus belong to the Keroplatidae, a group of small flies whose larvae inhabit moist, decaying organic matter and fungal substrates. The genus is distinguished within Keroplatidae by specific morphological features of the wing venation and genitalia. Heteropterna are likely active in humid forest environments where their larval prey and fungal occur.

Identification
Heteropterna are distinguished from other Keroplatidae primarily by wing venation patterns and male genitalia structure. The genus name refers to heteropterous (unequal-winged) characteristics in wing . Accurate identification to species level requires examination of microscopic features and dissection of terminalia. They may be separated from the related genus Keroplatus by details of the costal and tibial spurs.
