Genus Pygodasis
Synonyms and other taxonomic changes
Pygodasis was described by Bradley (1957) as a subgenus of Campsomeris. Argaman (1996) assigned generic status to Pygodasis, which was implicitly supported by Osten (2005).

Campsomeris (sensu stricto) is a Neotropical genus and does not occur in the USA and Canada.
Explanation of Names
Pygodasis Bradley, 1957
Two species occur north of Mexico:

1. Pygodasis ephippium (Say, 1837)
2. Pygodasis quadrimaculata (Fabricus, 1775)
