New Phycitiplex Porter (Hymenoptera, Ichneumonidae) from Subandean Desert in northwest Argentina

Abstract

Six new species of Phycitiplex (P. obscurior, P. tricinctus, P. unicinctus, P. peralta, P. trichroma, and P. lepidus) are described from material taken by Malaise trap in a humid ravine at Santa Vera Cruz in the Subandean Desert (Monte) of La Rioja Province (Argentina). These are keyed along with several closely related described species. Except for P. eremnus from central Chile, this genus is known only from the semiarid Chaco and Subandean biogeographic provinces in the northern half of Argentina. The only available host record is of Phycitiplex doddi (Cushman) reared from larvae of Cactoblastis cactorum (Berg), a phycitid moth that attacks prickly pear cacti
