Etymology.
The specific name is a noun in apposition taken from the scientific name of the bromeliad in which the
holotype
was collected,
Aechmea
distichantha
Lem.
Diagnosis.
Males of
Corinna aechmea
n. sp.
resemble those of
C. jecatatu
n.sp.
and
C. zecarioca
n. sp.
by presenting the RTA bifurcated, with a large median process in the prolateral suface, but it is readily recognized by the rounded apical tegular projection (
Figs. 50–51
); females differ from those of other species with secondary spermathecae separated by less than one diameter and copulatory opening median by the posterior margin of copulatory opening U-shaped and the posterior vulval plate with lateral rounded protuberances on the internal margin (
Figs. 52–53
).
