Original description:
Nemobius ohmachii Shiraki 1930

  Moderate in size, tawny brown, the sides being rather darker, elytra with very inconspicuous pale irregular markings.
  ♂. Head scarcely wider than pronotum, occiput rounded, forehead a little sloping, frontal rostrum a little wider than the first antennal joint, bristle-like hairs black; face slightly oblique, strongly shining; palpi light brown, the last 2 joints being pale yellowish; apical joint of maxillary palpi blackish tipped, distinctly longer than the 3rd and nearly twice as long as the 4th, moderately expanded at apex. Antennae light brownish; eyes oval; ocelli yellowish, rather large, disposed in a low-triangle.
  Pronotum rather transverse, furnished with black bristle-like hairs; anterior and posterior margins straight; lateral lobes dark brown, the inferior margin being paler, the later nearly horizontal, the anterior and posterior angles rounded.
  Abdomen rather short, dark brown with paler ventral side; supra-anal plate triangular, very short; subgenital plate a little shorter than long, the posterior margin very slightly emarginate in the middle; tergite just before supra-anal plate with two parallel bristle-like hairs.
  Legs concolorous, tawny yellow, posterior femora darker on the dorsal half. Anterior tibiae slightly compressed, provided at the external face only with a large oblong tympanum; metatarsi as long as two followings together. Intermediate tibiae and metatarsi narrower and a little longer than the anterior ones. Posterior femora moderate in length, very inconspicuously marbled with reddish brown at the external side; tibiae distinctly shorter than femora, armed with 4 spines on each margin; supero-internal spur longer than the remainings, intermediate ones on both sides equal in length, inferior spurs very short of which the internal one is shorter than the external spur; metatarsi longer than the two following joints together, furnished with 4 spines on the internal margin and only 2 on the external; each metatarsal spur furnished with two spines.
  Elytra reaching to the abdominal end, rounded at apex; speculum rather small, as long as wide, presenting no cell but having a short transversely oblique veinlet about the centre only; 3 cords, the two external of which are much curved, the first one sending a branch to the internal angle of speculum; diagonal vein long, nearly straight; oblique vein only one, very slightly curved inwards; apical field very much reduced, inconspicuously reticulate; lateral field dark brown, with 4 parallel veins. Wings wanting.
  ♀. A little longer than the male. Elytra leaving three last abdominal tergites free, more or less rounded at apex; longitudinal veins 4 on the dorsal field; lateral field dark castaneous, presenting 4 longitudinal veins. Supra-anal plate transverse, not triangular; subgenital plate very broad, about twice as wide as long, the posterior margin conspicuously emarginated in the middle; ovipositor very short, slightly curved upwards, about 2/3 as long as the posterior tibiae, apical valves comparatively long, of which the superior ones are very minutely serrate, having an apical hook.
  Length: Body ♂ 8, ♀ 8.5; pronotum ♂ 1.7, ♀ 1.6; elytra ♂ 4.5, ♀ 4; post. femora ♂ 5, ♀ 5.2; post tibiae ♂ 4, ♀ 4.4; ovipositor 3 ㎜.
  Hab.: Japan-Tokyo.
