Diagnosis

The new species is most similar to N. ripariensis (O. Pickard-Cambridge, 1872) and N. levyi Chatzaki, 2010 by having a similar tibial apophysis with a triangular protrusion and the tegulum extending prolaterally. It differs from them by the embolic division composed of a pike-like, straight embolus and a subtriangular terminal apophysis behind it (vs broad at base of embolus and with a claw-like terminal apophysis in N. ripariensis , see Chatzaki 2010: figs 47–48, and small and vertical embolus connected to a long, transverse terminal apophysis in N. levyi , see Chatzaki 2010: figs 28–29).

Etymology

The specific epithet is a noun in the genitive case and refers to Ameretat, the Avestan language name of the Zoroastrian divinity concept of immortality.
