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, 2B−C) (three in  N. bani sp. nov.). Males are unknown.    Etymology The specific name refers to the typelocality; noun in apposition.    Material examined    Holotype DOMINICAN REPUBLIC• 1 ♀; Pedernales Province, Las Mercedes, El Aceitillar[ 18.1251, 71.5616]; Carretera Km17;  1 Feb. 2005; A.
