Taxonomic Note
There is a homonym issue: Trichonyx Haupt, 1929 (Coleoptera: Staphylinidae) is distinct from Trichonyx used in Hymenoptera (Pompilidae). The sources provided contain conflicting information—Wikipedia and NCBI correctly place this in Coleoptera, while GBIF and Catalogue of Life entries refer to a different hymenopteran genus. The genus Trichonyx belongs to the Pselaphinae, a diverse group of myrmecophilous rove beetles.
