Subfamily Trisariinae Shear, 2020

Note: The diagnosis of this subfamily, it now appears, was too narrowly based on the type genus, Trisaria Shear, 2020 . However, we do believe that the genera grouped in it represent a monophyletic taxon. Presently we rely on gonopod and ninth leg characters for a diagnosis (see key above) but when more genera and species of Striariidae available have been studied and described, we expect to compose a more detailed diagnosis. The new genus Ralampia is particularly difficult to place; the two species may or may not have a flagellocoxite and though there is a branch of the gonopod that resembles one, it is not sheathed. Ralampia filamentosa n. gen., n. sp., has a lateral filamentous branch that appears similar to those seen in Trisaria . The ninth leg telopodites appear to be free. For the time being, however, we include this genus in Striariinae .
