Notes
This species is widely distributed in the Chûgoku Mountains. It is readily distinguished from other species previously considered N. reflexa distributed in Honshû by the concavity of the ventral surface of the aedeagal apex. It is distinguished from N. hikosana, described from nearby northern Kyûshû, by two pairs of setae on the ventral side of the sterna, versus one pair in N. hikosana.
Description
Body length: ♂, 9.97–10.32 mm (mean ± SD: 10.12 ± 0.13 mm, n = 5); ♀, 10.69–11.75 mm (mean ± SD: 11.22 ± 0.53 mm, n = 3). PPW/EL: ♂, 0.312–0.324 (mean ± SD: 0.320 ± 0.005, n = 5); ♀, 0.305–0.317 (mean ± SD: 0.313 ± 0.007, n = 3). Ventral surface of aedeagal apex deeply concave. Dorsobasal lobe absent. Dorsomedian lobe absent. Dorsoapical lobe with the basal part protruding dorsally; the protrusion as long as and narrower than the right laterobasal lobe; apical portion directed anteroventrally. Right laterobasal lobe large, with the width from a ventral view wider than the width of the gonopore protrusion from a lateral view. Left laterobasal lobe large, with the width from a ventral view wider than the width of the gonopore protrusion from a lateral view. Right lateroapical lobe bifurcated at the middle, with one apex directed posterolaterally and the other directed anterolaterally; the posterolateral apex further bifurcated. Left lateroapical lobe bifurcated at the middle, with one apex directed posterolaterally and the other directed anterolaterally; the anterolateral apex further bifurcated. Ventrobasal surface without swellings adjoining the laterobasal lobes; ventrobasal swelling large, semispherical from a lateral view.
