Limnebius
minute moss beetles
Limnebius is a genus of minute moss beetles in the family Hydraenidae, containing over 160 described species. The genus exhibits uniform external morphology but highly variable male genitalia, ranging from curved rod shapes in the subgenus Bilimneus to complex structures with up to seven longitudinal folds or appendages in Limnebius s.str. Species occur across multiple continents including Europe, Africa, Australia, and Papua New Guinea. The genus has been extensively studied for its morphological diversification and patterns of sexual dimorphism.
