Comments
.
Fannia tsachilas
sp. nov.
is morphologically similar to
Fannia iguaque
,
F. chingaza
and
F. sutagao
described by Grisales, Wolff and Carvalho (2012), due to the fore tarsomeres 3–5 flattened, but differs in the hind femur and the terminalia.
Etymology
. Name in apposition. The species epithet refers to the Tsachilás indigenous people, from
Ecuador
.
