Tachyporinae
Guides
Bryoporus
Bryoporus is a genus of rove beetles (Staphylinidae: Tachyporinae: Bolitobiini) established by Kraatz in 1857. The genus has an almost cosmopolitan distribution with records from Europe, North America, and other regions. Taxonomic revisions have clarified its relationship to related genera Bryophacis, Bolitopunctus, and Neobolitobius, particularly for North American species. The genus includes multiple species, with Bryoporus cernuus (Gravenhorst, 1806) being a representative species.
Cilea
Cilea is a genus of rove beetles (Staphylinidae: Tachyporinae: Vatesini) established by Jacquelin du Val in 1856. The genus has been taxonomically confused with Leucoparyphus Kraatz, and its priority over that name has been established. In North America north of Mexico, only Cilea silphoides (Linnaeus) is present. The genus is distinguished from the related genus Coproporus by morphological characters including male genitalia structure.
Cilea silphoides
Cilea silphoides is a rove beetle (Staphylinidae: Tachyporinae) originally described by Linnaeus in 1767 as Staphylinus silphoides. It is the sole species of the genus Cilea treated in the 1975 North American revision by Campbell and Davies, which provided detailed morphological descriptions, distribution mapping, and male genitalia illustrations. The species has been taxonomically confused with related genera, and its name has undergone clarification regarding generic priority. It is distinguished from the related genus Coproporus by structural features of the male genitalia and external morphology.
Coproporus
Coproporus is a genus of rove beetles in the family Staphylinidae, subfamily Tachyporinae, tribe Vatesini. The genus has a cosmopolitan distribution with records from North America, Europe, and South America. Taxonomic revision has clarified confused generic usage and resolved synonymies, particularly distinguishing Coproporus from the related genus Cilea. Nine species occur in North America north of Mexico, with additional species documented from Mexico, Panama, Argentina, and Brazil.
Coproporus pulchellus
Coproporus pulchellus is a species of rove beetle in the family Staphylinidae, originally described by Erichson in 1839 under the basionym Tachinus pulchellus.

Coproporus ventriculus
Coproporus ventriculus is a species of rove beetle in the family Staphylinidae, subfamily Tachyporinae. It belongs to a genus associated with decaying organic matter and fungal habitats. The species has a broad North American distribution spanning much of Canada and the United States. Like other members of Tachyporinae, it is likely associated with rotting substrates where it feeds on fungal spores and hyphae, though specific ecological studies on this species are limited.
Ischnosoma
Ischnosoma is a genus of rove beetles (Staphylinidae: Tachyporinae) established by Stephens in 1829.

Ischnosoma contains numerous species distributed across Eurasia, the Americas, and Australia, with particularly high diversity in China, where over 29 species have been documented. North and Central American species have been revised extensively, with 18 species recognized in that region alone.
Ischnosoma flavicolle
Ischnosoma flavicolle is a species of rove beetle in the family Staphylinidae, subfamily Tachyporinae.
