False Soldier Beetles, False Fireflies
Subfamily Guides
2Omethidae is a small of elateroid beetles commonly known as false soldier beetles. The family comprises approximately 40 in 11 , divided into four : Driloniinae, Matheteinae, Omethinae, and Telegeusinae. Telegeusinae, formerly treated as a separate family Telegeusidae, was reclassified as a subfamily within Omethidae based on phylogenetic studies. The family's remains poorly known, with larvae undescribed and ecological data limited to collection records.

Identification
Omethidae can be distinguished from Cantharidae (true soldier beetles) by morphological features of the telegeusine , including elongated maxillary palps. Within Telegeusinae, identification relies on antennal structure (serrate versus other forms), proportions ( size relative to head width, vertex proportions), and ventrite number. Pseudotelegeusis species exhibit serrate from antennomeres III to X, while other may differ in these characters.

Taxonomic History
Telegeusinae (long-lipped beetles) were formerly treated as Telegeusidae but are now classified as within Omethidae. The classification of Phengodidae relative to Telegeusinae remains under study, with some analyses suggesting inclusion or sister-group relationship.
