Etymology.
The specific epithet is referring to an Andean formation and
type
locality called “Serranía del Perijá”. It is the most northern branch of the Andean mountains.
Diagnosis.
Females of
Patrera perijaensis
n. sp.
, resemble those of
P. florezi
n. sp.
and
P. wiwa
n. sp.
, by having the similar shape of hood and n-shaped copulatory ducts (
Figs 16
F–G, 21F–G), but can be diagnosed by having very large and subrounded hood (thinner in
P. florezi
), wide copulatory ducts, and larger spermathecae (thinner and smaller respectively in
P. florezi
) (
Fig. 17
B–C).
