Diagnosis.

Following Platia and Schimmel (2007): length 13-16 mm, width 3.2-4 mm; red-brown with vague brown-black areas on head and pronotum; frons deeply impressed medio-anteriorly; antennae falling short of pronotal hind angles by about one antennomere, feebly serrate from antennomere 3, antennomere 2 more than twice longer than wide, antennomere 3 subtriangular, 2.5 times longer than 2, and longer than following; pronotum slightly longer than broad, widest at hind angles, disc strongly convex, abruptly sloping posterad, where with a trace of short median furrow, hind angles truncate, not divergent, with a short carina following edge, punctation coarse and variable; scutellar shield 1.2 times longer than wide, gently convex, sparsely punctate; elytra as broad pronotal posterior, 2.5-2.6 times longer than pronotum, base near humeral angles with a short spine.

Distinguished from other Scutellathous in China by elytral spine and red-brown colour. Distinguished from S. yamashitai by the shorter antennae not reaching the apices of the hind angles of the pronotum and rounded pronotal anterior angles.

Remarks.

No additions to the male genitalia except the length (1.75 mm) in original description. But we can see from the original image that the penis is reaching a little beyond the apex of the parameres, gradually narrowed to a pointed apex and the parameres are thick, strongly sinuate laterally at midlength, weakly tapered to a blunt apex.
