Type species: Striaria granulosa Bollman, 1888. The exact identity of the type species has yet to be established, as the type specimens are lost and there are no known collections from the type locality (Beaver Creek, Jefferson Co., Tennessee), or nearby.According to Hoffman (1999, p. 209) the types were originally deposited in the United States National Museum of Natural History (Smithsonian Institution), but by 2012 they could no longer be found there.
