- Nebria reflexa : Uéno (1985)[1]: 56 (part); Nakane (1963b)[2]: 19 (part).
Notes
This species in known from two localities near Mount Hakusan where N. niohozana and N. pisciformis sp. nov. co-occur. This species is distinguished from N. niohozana by a smaller body size and larger PPW/EL (values for male N. niohozana from Mount Hakusan: body length, 10.24–10.90 mm; PPW/EL, 0.289–0.321 (n = 4); values for females are not shown due to unavailability of specimens), and from N. pisciformis, by larger PPW/EL and a trifurcate apical margin of the dorsoapical lobe.
Description
Body length: ♂, 9.27–9.65 mm (mean ± SD: 9.48 ± 0.19 mm, n = 3); ♀, 10.21–10.60 mm (mean ± SD: 10.46 ± 0.13 mm, n = 4). PPW/EL: ♂, 0.323–0.341 (mean ± SD: 0.334 ± 0.009, n = 3); ♀, 0.311–0.320 (mean ± SD: 0.316 ± 0.004, n = 4). Ventral surface of aedeagal apex not concave. Dorsobasal lobe present. Dorsomedian lobe absent. Dorsoapical lobe with the basal part protruding dorsally; the protrusion as long as and 1.5 times as wide as the right laterobasal lobe; the apical portion directed ventrally, twice as wide as the subapical constriction; the apical margin divided into four projections. 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, strongly bent at the middle in an anterior direction. Left lateroapical lobe moderate in size, more or less bifurcate. Ventrobasal surface almost flat, without swellings.
Type materials
Holotype: ♂ (KS), Arashiguchi, Kamiuchinami, Ôno-shi, Fukui Prefecture, Japan, 26.v.2019, S. Inoue leg. Paratypes: 1♀ (KS), same data as the holotype; 2♂3♀ (NARO), Amô Pass–Shoyashiki, Hida-shi, Gifu Prefecture, Japan, 19.vi.1972, K. Tanaka & H. Ohira leg.
Etymology
The specific name derives from the Latin word furcata (forked) and refers to the apical margin of the dorsoapical lobe.
