Strangalia subtilis ab. ohishii Matsushita & Tamanuki, 1937: 147.

Male. Moderate sized. Length 17.0 mm, width 4.9 mm. Body mostly black; maxillary palpi, labrum and apical margin of clypeus dark reddish brown; elytral maculae yellowish brown, first macula near base and semicircularly bowed along basal margin; second and third maculae transverse, slightly broaden beside suture and narrowed laterad, second smaller than third macula; fourth macula near apex, small and triangular. Head and borders of pronotum and scutellum densely with long yellowish brown hairs; ventral surface densely clothed with yellowish brown hairs.

Head narrower than pronotal base with dense but fine punctures, a shallow but distinct median line extending from frons to occiput through vertex; frons with width 1.25 times of height, clypeus trapezoidal, vertex widely concave. The apical segment of maxillary palpi thickened, 1.5 times as long as the penultimate segment and the apex obliquely truncated. Antenna slender and the last segment exceeding the elytral apex; the fifth to tenth segments thickened ecto-apically, but not distinctly serrate; scape thick and short, nearly equal to the fourth, shorter than the third; the third nearly equal to the fifth. Pronotum shorter than basal width and strongly convex; disk with dense but fine punctures and an indistinct median longitudinal unpunctured line, which transversely depressed along basal margin. Scutellum triangular. Elytra 2.4 times as long as humeral width and dehiscent from apical seventh, sides straightly tapered to apical seventh, apex obliquely emarginated with sharply pointed outer angle and dull inner angle; disk densely provided with setigerous and small punctures. Tibiae of hind leg dilated apicad, the first tarsal segment 2.25 times as long as the second segment.

Female. Body more or less thick and large, but similar to male in general features. Different from male with following features: length 18.2 mm, width 5.5 mm; tibiae and tarsi yellowish brown, femurs and antennae dark brown; antennae reaching apical fifth of elytra, the fifth to tenth segments not inflated ecto-apically; pronotum densely clothed with yellowish brown hairs; elytra 2.2 times as long as humeral width; elytral maculae much larger, conjoint suturally and the basal two full conjoint. The first segment of hind tarsal 2.75 times as long as the second segment.
