Note. Malloch (1921) described D. pribilofensis from St. Paul Island in the Pribilof Islands, Alaska, and D. inaequalis from “Northern Ural Mountains” (Malloch 1922). The holotype of D. inaequalis should be in the Finnish Museum of Natural History, Helsinki, Finland, but it was not found there by Hennig (1962b) who did not otherwise know the species and reproduced Malloch’s original description. We have not seen either type, but Malloch’s description of the structure of the fore tarsomeres is the same for both species and is actually unique in the genus Drymeia. For this reason we have no hesitation in proposing this synonymy.
