Etymology
. The specific name is a noun in apposition taken from the
type
locality.
Diagnosis
. The males of
N. perote
differ from
N. oaxaca
in having the RTA with ventral projection and a deep excavation (
Fig. 33
e), and from
N. punta
in having tegular median process not exceeding the conductor length (
Fig. 33
d). The females distinguish from
N. comaltepec
in having the atrium less procurved, and from
N. oaxaca
,
N. popoca
, and
N. punta
in having the atrium with two pairs of sclerotized sharp tips (
Fig. 33
f, h).
