Hilgardia, 1965, vol. 36, issue 7

Abstract: The genus Cryptognathus is defined and the relatedness of its family to others now included in the superfamily Raphignathoidea is discussed. Eight new species from California and two from the Galapagos Islands are described. One previously named subspecies, C. cucurbita cucurbitella, is elevated to specific rank and redescribed. The species included in this study comprise two distinct groups. Characteristic patterns of ornamentation on the dorsal and ventral body plates are found to be especially useful for distinguishing one species from another. A key for identifying females of the new species is provided.
