Diagnosis

Males of Hatitia machiguenga sp. nov. resemble those of H. canchaque and H. oxapampa sp. nov. by the projected tegulum ( Figs 11D–H , 12C–H , 13C–H ) but differ by the keel-shaped projection of the tegulum and the divided cymbial conductor ( Fig. 13C–H ).

Etymology

The specific name refers to the Machiguenga indigenous group. This is the best known and largest of the groups that live within the Manu National Park.
