Parsons, C.T. 1938. Notes on North American Nitidulidae, II: Cryptarcha Shuckard. Psyche: A Journal of Entomology 45(2-3): 96-100.

The genus Cryptarcha embraces many species which are found in all parts of the world. The six species occuring in the United States have apparently two origins. Cryptarcha ampla, grandicollis, glabra and strigatula n. sp. are closely related to the numerous Neotropical forms, whereas the smaller concinna and gila n. sp. are more closely related to the Palaearctic imperialis Fabr. and its allies. The apparently two origins are reflected in the two subgenera, which are keyed below.
