Stilicopsina
Casey, 1905
Genus Guides
2Stilicopsina is a subtribe of rove beetles (Staphylinidae) established by Casey in 1905, classified within the tribe Lathrobiini and Paederinae. As a subtribe, it represents a grouping of sharing derived morphological characteristics that distinguish them from other Lathrobiini. The subtribe is part of the megadiverse Staphylinidae , one of the largest families of organisms. within Stilicopsina are small to medium-sized beetles with the characteristic reduced and exposed abdominal segments typical of rove beetles. The subtribe has been documented in iNaturalist with over 100 observations, indicating some level of field detectability.

Identification
Stilicopsina can be distinguished from other subtribes within Lathrobiini by subtle combinations of characters in the male genitalia, tarsal formula, and details of the mouthpart structure. Members lack the distinctive features that define the subtribe Stilicina, such as particular arrangements of setae on the pronotum. Identification to subtribe level requires examination of microscopic characters and is generally not feasible from field photographs alone. Specimens must be compared against published revisions of the Lathrobiini.

Habitat
within Stilicopsina occur in terrestrial , with members of the parent tribe Lathrobiini frequently found in leaf litter, decaying vegetation, and moist soil environments. Specific microhabitat preferences for the subtribe as a whole remain poorly documented.
Distribution
The subtribe has been recorded from North America based on the original description and subsequent taxonomic work. The precise geographic extent is not comprehensively mapped, as many -level records in historical literature require verification against modern concepts of the subtribe.
Ecological Role
As part of the rove beetle fauna, members of Stilicopsina likely function as or scavengers in soil and litter , though specific ecological studies are lacking.

Taxonomic history
Casey (1905) originally proposed Stilicopsina as a group name, and it has been maintained in modern classifications of the Paederinae based on phylogenetic analyses of morphological data. The subtribe includes the Stilicopsis and related genera, though generic limits have been revised multiple times.
Research needs
The subtribe would benefit from molecular phylogenetic study to test the monophyly of currently included and to clarify relationships within Lathrobiini. No comprehensive modern revision exists.
