Notes.

This species is known only from the type locality, Mount Kuragatake, a low mountain located northwest of Mount Hakusan. It is distinguished from N. niohozana , which is also distributed on Mount Hakusan, by a larger PPW/EL.

Description.

Body length: ♂, 9.59 mm (n = 1); ♀, 10.28 mm (n = 1). PPW/EL: ♂, 0.342 (n = 1); ♀, 0.334 (n = 1). Ventral surface of aedeagal apex not concave. Dorsobasal lobe present. Dorsomedian lobe absent. Dorsoapical lobe with the basal part weakly swollen; the left dorsolateral surface behind the subapical constriction weakly swollen; the apical portion directed ventrally, less than twice the width of the subapical constriction; the apical margin very slightly bifurcated. Right laterobasal lobe small, with the width from the ventral view narrower than the width of the gonopore protrusion from the lateral view. Left laterobasal lobe small, with the width from the ventral view narrower than the width of the gonopore protrusion from the lateral view. Right lateroapical lobe small, weakly bent at the middle in an anterolateral direction. Left lateroapical lobe with the posterior part small and weakly bent at the middle in an anterolateral direction; the anterior part largely swollen, directed left-dorsoposteriorly. Ventrobasal surface almost flat, without swelling.

Type materials.

Holotype: ♂ (NARO), Mount Kuragadake, Kanazawa-shi, Ishikawa Prefecture, Japan, 20.v.1962, S. Takaba leg.; Paratype: 1♀ (NARO), same data as the holotype.

Etymology.

The specific name refers to Mount Kuragadake, the type locality of this new species.
