. The specific epithet is a noun in apposition taken from the typelocality.
Diagnosis
.
♂♂
of
S. itabaiana
differ from all other
Synotaxus
species by the large, flattened and granulated paracymbium (
Figs. 15–16
).
♀♀
present lateral atria on the epigynum (
Fig. 17
), as
S. turbinatus
and
S. ecuadorensis
, but differ by the suboval shape of spermathecae (
Fig. 18
).
