Diagnosis
Elytra with a pale yellow transverse fascia narrowly interrupted at suture, just before the middle; male antennomere III ear-like shaped.
Type material examined
Holotype
JAPAN: ♂, [Hedozaki, Kunigamison, Okinawa, 13 Jun. 1955, R. KAWASAKI.] (SEHU).
Paratypes
JAPAN: 3 ♀♀, same data as for the holotype (SEHU).
Redescription
Male
Body (Fig. 1H) oblong oval, shining, sparsely covered with gray pubescence. Coloration of head, pronotum and elytra black; antennae yellow, but apical 6 or 7 segments black; elytral fascia pale yellow, narrowly interrupted at suture; legs yellow; base of femora dark; hind femur and tibia black.
Head densely punctate; eyes normal, prominent; HL/HW 0.58. Antennae (Fig. 4H) long, reaching base of elytra; antennomere I long and stout; antennomere III ear-like shaped, deeply concave in dorso-mesal portion; L/W = 1.77; approximate ratio of each antennomere (n = 1) as 5.60: 1.00: 8.48:1.16: 1.24: 1.24: 1.40: 1.60: 1.24:1.60: 2.40. Pronotum transverse, sparsely punctured in middle, densely so in lateral and posterior parts; PL/PW 1.17. Elytra oblong-ovate, a little broader than prothorax, then gently dilated to behind middle, sparsely punctate; EL/EW 1.51; EL/PL 2.70; EW/ PW 1.52; TL/EW 2.43. Male genitalia not examined.
Female
Similar to male in general appearance (Fig. 2H); coloration of antennae yellow, with apical 5 or 6 segments black; HL/HW 0.64–0.76 (0.70); PW/PL 1.13–1.18 (1.15); EL/EW 1.50–1.65 (1.57); EL/PL 2.71–2.82 (2.78); EW/PW 1.45–1.61 (1.54); TL/EW 2.48–2.66 (2.54). Antennae (Fig. 5H) long; antennomere III distinctly expanded laterally, shallowly concave in dorsal portion; L/W = 2.07; approximate ratio of each antennomere (n = 1) as 7.11: 1.00: 5.00:2.24: 2.24: 2.11: 1.97: 2.18:2.19: 2.37: 3.42.
Measurements
Male(n=1):TL 3.04mm; HL 0.45 mm; HW 0.77mm; PW 0.82 mm; PL 0.7mm; EL 1.89 mm; EW 1.25mm.
Female (n = 3): TL 3.60–3.90 (3.79) mm; HL 0.58–0.63 (0.61) mm; HW 0.83–0.90 (0.88) mm; PW 0.90–1.00 (0.9) mm; PL 0.80–0.87 (0.84) mm; EL 2.17–2.45 (2.34) mm; EW 1.45–1.57 (1.49) mm.
Distribution (Fig. 11A)
Japan (Okinawa-jima).
Remarks
This species is rare and no additional specimens besides the type series have been collected. This species was recorded from Kyushu by Satô (1989) and Yoshitomi & Hayashi (2011), but we regard this as a simple mistake.
Biological notes
The type series was collected from the northernmost cape of the island, and this species probably inhabits beach plant communities.
