Diagnosis
Females of
N. aceitillar
sp. nov.
resemble those of
N. bani
sp. nov.
(
Figs 4
D−E, 5E−G) by the epigyne with MS heart-shaped, with anterior median indentation and by the SP packed within a sclerotized structure with internal ducts with more than one twist. They are distinguished from those of the latter species by the indentation extending posteriorly, surpassing half MS length (
Figs 1C
,
2A
) (not extending posteriorly in
N. bani
sp. nov.
) and by the SP bearing only two twists (
Figs 1D
,
2
B−C) (three in
N. bani
sp. nov.
). Males are unknown.
Etymology
The specific name refers to the
type
locality; noun in apposition.
