Hydnosella globithecaW. Eugene Hall
Hydnosella currently contains a single species (Dybas, 1961) found in North America. The type species was found on the undersurface of the fungus Steccherinum rhois (=S. ochraceum), belonging to the Hydnaceae. This differs from other nanosellines, which are usually associated with fungus of the Polyporaceae.
Hydnosella can be distinguished form other nanosellines based on the 'globular' spermatheca and cylindrical pits located at the basal angle of the pronotum (Dybas, 1961, 1990). The mesosternal process is directed posteriorly, and the metasternal lines are reduced in length.
