Notes.

This species is known only from the type locality, Mount Kasuga. Although similar in body size and PPW/EL to N. furcata , N. shirokawa , and N. kuagadakensis , it is distinguished from these species by the shape of the endophallus.

Description.

Body length: ♂, 9.92-10.00 mm (n = 2); ♀, 9.94-10.56 mm (mean ± SD: mean ± SD: 10.34 ± 0.34 mm, n = 3). PPW/EL: ♂, 0.332-0.345 (n = 2); ♀, 0.314-0.330 (mean ± SD: 0.324 ± 0.009, n = 3). Ventral surface of aedeagal apex not concave. Dorsobasal lobe present. Dorsomedian lobe small. Dorsoapical lobe with basal part protruding posterodorsally; protrusion smaller than the right laterobasal lobe; the apical portion directed ventrally. Right laterobasal lobe large, with the width from the ventral view wider than the width of the gonopore protrusion from the lateral view. Left laterobasal lobe large, with the width from the ventral view wider than the width of the gonopore protrusion from the lateral view. Right lateroapical lobe small, simply swollen. Left lateroapical lobe bifurcated at the base, with one apex directed posterolaterally and the other directed anterolaterally; the posterolateral apex larger than the anterolateral apex; the posterolateral apex larger than the anterolateral apex and slightly smaller than the right laterobasal lobe. Ventrobasal surface with a pair of swelling adjoining each laterobasal lobe; swellings unconnected; ventrobasal swelling absent.
