Taxonomic history
Cydnoides was established by Malloch in 1919. The name superficially resembles 'Cydnus' (a genus in Cydnidae, the burrower bugs), but Cydnoides belongs to the distinct family Thyreocoridae. The epithet 'cydnoides' used in Talpoblissus cydnoides (Blissidae) refers to resemblance to Cydnus, not to the genus Cydnoides itself—this reflects convergent body forms among unrelated true lineages.
