Etymology.
The specific name is an adjective referring to the marked and conspicuous lateral carina on the male chelicerae.
Diagnosis.
The male of
E. carinata
sp. nov.
resembles those of
E. igarape
Silva, Lise & Carico, 2008
by the presence of the ventral division of the median apophysis (VD) (
Silva
et al
. 2008
, p. 96, figs 100, 101), but can be distinguished by the shorter and wider ectal division (ECD) of the retrolateral tibial apophysis (RTA) (
Fig. 2
).
