Etymology.
The specific epithet is a Latin adjective in reference to the turquoise color of the abdomen.
Diagnosis.
Males and females can be distinguished from all
Ochyrocera
by their bright turquoise abdomen, apically with purplish chevrons (
Fig. 18
). Furthermore males can be diagnosed from all
Ochyrocera
by their unique horn-shaped cymbial apophysis (
Fig. 19
); females can be diagnosed by their dark spermathecae and median thumbshaped projection (
Fig. 22
).
