Diagnosis
Males of
T. maracay
sp. nov.
resemble those of the
silhavyi
group by having the apophysis at the base of the embolus laminar, but differ from the other species by having the retrolateral tibial apophysis short, curved apically and presenting a basal projection rounded (
Figs 25C–E
,
26C
). Females resemble those of
T. silhavyi
and
T. arawak
sp. nov.
by having the epigynal plate with a wide atrium, but differ by having the copulatory ducts slightly narrowing in the anterior region (
Figs 25F–G
,
33D
).
Etymology
The specific name is a noun in apposition taken from the
type
locality Maracay, currently the capital of the State of
Aragua
in
Venezuela
.
