Diagnosis

Males of Tafana kunturmarqa sp. nov. resemble those of T. straminea and T. ruizi sp. nov. by having the retrolateral tibial apophysis conical, but differs by having the embolus short and the apophysis at the base of the embolus larger ( Fig. 14C–E ). Females resemble those of T. straminea and T. ruizi sp. nov. by having the epigynal plate with atrial septum, but differ by having the secondary spermathecae above the primary spermathecae, rounded, and fertilization ducts smaller than primary spermathecae ( Figs 14F–G , 32I ).

Etymology

The specific name, a noun in apposition, is a tribute to the Pre-Colombian language ‘Quechua’, originated in the central Andes. The meaning of the expression ‘Kuntur marqa’ in this language is ‘Condor’s nest’.
