Lepiceridae

Definition

A family of minute myxophagan beetles (Coleoptera) containing the single extant genus *Lepicerus* with three described Neotropical species. Members are among the smallest beetles, associated with wet habitats and presumed to feed on microbial films or algae. The family also includes the fossil genus *Lepiceratus* from the Late Cretaceous of Southeast Asia, indicating an ancient Gondwanan distribution disrupted by continental drift.

Etymology

From the genus *Lepicerus* (Greek root uncertain, possibly 'scale' + 'horn') + Latin family suffix -idae

Example

Adult Lepiceridae are rarely collected due to their minute size (<2 mm) and cryptic habits in tropical seeps and splash zones; the Mexican species *Lepicerus inaequalis* is known from only a handful of specimens.

Usage Notes

Treat as a family-rank taxon; the family is sometimes grouped with other myxophagan families (Sphaeriusidae, Hydroscaphidae) in discussions of the smallest beetle lineages. Fossil and extant distributions are disjunct, supporting a relict status.
