Diagnosis

Males of Tafana huatanay sp. nov. resemble those of T. riveti , T. humahuaca sp. nov. and T. nevada sp. nov. by having the short embolus, but differ by having the base of the embolus wide ( Figs 19C , 20A–C ). Females resemble those of T. riveti , T. humahuaca sp. nov. and T. nevada sp. nov. by having the epigynal plate with curved lateral lobes in anterior region, but differ by having the copulatory ducts medially flattened and secondary spermathecae on the sides of the primary spermathecae in dorsal view ( Figs 19F–G , 33A ).

Etymology

The specific name, a noun in apposition, is a tribute to the ‘Sacred Valley of the Incas’ called Huatanay.
