Etymology
. The specific name is a patronymic in honor of Freddy Bravo, the collector of the
types
from Bahia.
Diagnosis
. Males of
Umuara freddyi
resemble those of
Umuara fasciata
by the shape of the apophysis of embolic process (see
Brescovit, 1997
, figs. 242–245), but can be recognized by the retrolateral tibial apophysis long and not bifid (
Figs. 2
D, E). Females resemble those of
U. junin
by the epigynum with large median hood and curved lateral borders (see
Brescovit, 1997
, figs. 255–256), but can be distinguished by the more elongated median hood and by the lateral borders not curved basally (
Fig. 2
G).
