Cryptobiina
Casey, 1905
Genus Guides
4Cryptobiina is a subtribe of rove beetles within the Staphylinidae, Paederinae, and tribe Paederini. It was established by Casey in 1905. Members of this subtribe are part of a diverse lineage of small to medium-sized beetles characterized by shortened that expose most of the . The subtribe includes multiple , though precise generic composition varies across taxonomic treatments. Cryptobiina are primarily found in tropical and subtropical regions, with documented occurrences in South America including Colombia.

Identification
Cryptobiina can be distinguished from other subtribes within Paederini by combinations of characters in the male genitalia, tarsal formula, and pronotal structure. Specific diagnostic features vary by and require examination of microscopic characters. Members generally exhibit the typical Paederinae body plan with slender, somewhat flattened bodies and relatively long legs compared to body size.

Distribution
Documented from South America, with specific records from Colombia (El Tuparro). The subtribe's distribution likely extends more broadly through Neotropical regions based on the distribution patterns of related Paederinae, though precise range boundaries remain poorly documented.

Taxonomic Uncertainty
GBIF lists Cryptobiina as a with authorship Bordoni, 1975 and status 'doubtful', reflecting taxonomic confusion. This appears to conflate subtribe-level and genus-level concepts. The Catalogue of Life and iNaturalist treatments as a subtribe (Casey, 1905) are more widely accepted in current Staphylinidae classification.
iNaturalist Observations
The subtribe has 3,157 observations on iNaturalist, indicating moderate documentation effort, though many records may not be identified to subtribe level by observers.
