Diagnosis
Males of
Tafana pittieri
sp. nov.
resemble those of the
silhavyi
group by having the secondary looping in the middle in the tegulum, but differ from them by having the large laminar, ring-shaped apophysis at the base of the embolus and retrolateral tibial apophysis short and truncated (
Fig. 28C–E
). Females differ from the other species by having the lateral lobes wing-shaped in the median region, covering part of the atrium, and secondary spermathecae with slender shape (
Fig. 28F–G
,
33F
).
Etymology
The specific name is a patronym in honor of Henri Pittier, a botanist, geographer and ethnologist who devoted himself to the study of the flora and fauna in the National Park Henri Pittier, where the specimen was collected. In the year of 1953 the park (until then called Rancho Grande) was renamed in honor of H. Pittier.
