A new Central American <i>Dasydemella</i> (Psocoptera = Corrodentia; Amphipsocidae)

Abstract

Dasydemella obrienorum sp. nov. is the fifth species known in Dasydemella (Psocoptera = Corrodentia), an American psocid genus formerly recorded only from Mexico and Brazil; the new species was collected in Panama and Guatemala. The genitalia of both sexes, as well as wings, a lacinal tip and a pretarsal claw are illustrated; measurements, ratios and ctenidial counts are also given for one specimen of each sex. The characteristic wing markings and the shape of the pterostigma separate D. obrienorum from the other species in the genus. The types are deposited in the author's collection.
