Taxonomy
Since the description of this genus, it had remained extremely obscure being little featured in catalogues. This genus was first described by John O. Westwood in 1845 with the type species being Cryptogenius miersianus. Cryptogenius was originally placed in the family Trogidae however it was removed from this family in 1986 and placed as the probable closest relative to the genus Anaides on the subfamily Anaidinae.[1] In 2001, H. F. Howden grouped this genus with Callosides to form the newly proposed tribe Cryptogeniini.[3] A study in 2023 by Costa-Silva, V. & Vaz-de-Mello, F. Z. recognized only two species: Cryptogenius miersianus and Cryptogenius westwoodi which was described as a new species.[2]
