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.
