Two new species of the myrmecophilous histerid genus Chlamydopsis Westwood are described. One, C. doutti Caterino, new species, belongs to the C. epipleuralis group, and is closely related to C. convexa Caterino. The close relatives of this species all occur in temperate areas in southeastern Australia, while C. doutti is known only from a single locality in central Queensland. The other species, C. chadster Caterino, new species, represents the third true Chlamydopsis known from New Guinea. It is known only from the type locality on Japen Island, off the northwest coast of Papua, Indonesia, and is not obviously related to the other two New Guinean Chlamydopsis.
