Diagnosis. Color of body blackish-brown, generally monocolor. Scales on head, pronotum, scutellar shield, and elytra black, but cream-colored in some specimens on a part of head, anterior part of pronotum, posterior part of intervals V and VII, and apical part of elytra. Elytra (Fig. 4F) with 10 longitudinal rows of window punctures; window punctures transverse.
Male (Fig. 1K). Eyes (Fig. 3K) small, slightly prominent. Antennae long and slender, reacing about proximal 2/3 of elytra; AL/TL 0.71–0.80 (0.77); approximate ratio of each antennomere (n = 10; average) as 2.96: 1.00: 3.11: 3.74: 4.22: 4.44: 4.61: 4.55: 4.69: 4.57: 5.78. Anterior pronotal angles (Fig. 3K) almost right-angled. HL/ HW 0.65–0.73 (0.69); PW/PL 1.32–1.46 (1.40); EL/EW 2.73–3.06 (2.93); EL/PL 5.68–6.62 (6.23); EW/PW 1.41– 1.67 (1.52); TL/EW 3.53–4.02 (3.81); EYL/EYW 1.66–2.22 (1.92); TEL/HL 0.13–0.18 (0.16). Apex of sternite IX acuminate, but bifid in some specimens. Bifurcate process (Fig. 12C) V-shaped, rectangular in basal part. Parameres (Fig. 12A, B) with posterior projection of dorsal margin (pp) arcuate; apical hook simply curved and pointed; ventro-marginal spines (vms) long, reaching apical hook. Apical margin of dorsal plate (dp) shallowly concave. Apical margin of mesal lobe (ml, Fig. 12A) shallowly concave.
Female (Fig. 1L). Eyes (Fig. 3L) small, slightly prominent. Antennae long and relatively stout, reaching about proximal 3/4 of elytra; AL/TL 0.69–0.85 (0.75); approximate ratio of each antennomere (n = 6; average) as 3.16: 1.00: 3.23: 3.72: 3.93: 4.31: 4.57: 4.61: 4.49: 4.29: 5.55. Anterior angles of pronotum (Fig. 3L) almost right-angled. HL/HW 0.62–0.69 (0.66); PW/PL 1.38–1.46 (1.42); EL/EW 2.63–2.98 (2.82); EL/PL 5.97–6.56 (6.18); EW/PW 1.42–1.66 (1.55); TL/EW 3.45–3.87 (3.67); EYL/EYW 1.88–2.40 (2.13); TEL/HL 0.10–0.16 (0.14).
Distribution. Japan: Honshu, Shikoku, Kyushu.
Remarks. Judging from the original description (Miyatake, 1985a), the holotype was collected from Mt. Takanawa, near Matsuyama, and the "Mt. Nakanawa" written on the label was considered to be a simple mistake.
