Diagnosis
Males of
Tafana humahuaca
sp. nov.
resemble those of
T. riveti
and
T. nevada
sp. nov.
by having the short embolus, but differ by having the apophysis at the base of the embolus truncated, extremely short and with excavation between the base of the embolus and the apophysis (
Fig. 15C–E
). Females resemble those of
Tafana nevada
sp. nov.
by having the epigynal plate, but differ by having atrium narrow in the anterior region, small hood with lateral lobes extremely curved in the anterior region (
Figs 15F–G
,
32J
).
Etymology
The specific name, a noun in apposition, is a tribute to ‘Quebrada de Humahuaca’, a deep canyon located in
Jujuy Province
, the
type
locality.
