Family Striariidae Bollman, 1893

The taxonomic characters useful in distinguishing species of Striariidae were discussed by Shear (2020), with reference to Striaria columbiana Cook, 1899 (Virginia, USA). The members of the family may be easily recognized in the field by the broad, hooded collum (col, Figs 1 , 14 ) and the crested pleurotergites ( Fig. 15 ). All presently known striariids have 30 pleurotergites.
