Prionoglarididae
Large-winged Barklice
Prionoglarididae is a family of small, winged insects in the order Psocodea, commonly known as barklice or booklice. The family contains approximately 9 genera and over 20 described species distributed across Europe, Asia, Africa, and North America. Members are characterized by reduced or simplified lacinia (mouthpart structures) in adults and highly specialized male genitalia. The genus Neotrogla is notable for exhibiting sex-reversed genitalia, with females possessing an intromittent organ (termed a gynosome) and males having vagina-like structures. Most species inhabit cave environments.
