Etymology.
The specific name is a Latin adjective meaning gigantic, an allusion to the larger size of this species compared to the remaning
Tupirinna
.
Diagnosis.
Males of
Tupirinna gigantea
sp. nov.
differ from those of all other species with basally divided ventral lobe of RTA (
T. coari
sp. nov.
,
T. zebra
sp. nov.
and
T. urucu
sp. nov.
) by the bifid ventral process of the ventral lobe of the RTA (
Fig. 11E
). They further resemble those of
T. coari
sp. nov.
by the short embolus, directed retrolaterally, and the long, narrow
AS
, differing by the filiform, curved embolar tip (
Fig. 11E, F
). Females resemble those of
T. coari
sp. nov.
by the concave epigynal plate, but can be recognized by the posteriorly positioned copulatory opening (
Fig. 11G, H
).
