Scolytoplatypus raja Blandford, 1893b ( Figure 63 ) = himalayensis Stebbing, 1914 This species is diagnosed by the following morphological characters: ♂ frons strongly concave up to vertex; surface reticulate, roughened and with sparse bent hairs more distinct on upper half; the upper margin of frontal cavity with uniform curled hairs; eyes elongate and weakly convex; antennal club large and lanceolate, slightly longer than scape and funicle combined together; pronotum nearly as long as wide and widest at the middle; basal margin strongly bisinuate, lateral sides with basal emargination and ridged beyond middle; postero-lateral corners rather acute and projected outwards; surface opaque and reticulate with close large punctures, except longitudinal impunctate area; hairs inconspicuous; prosternum with two tubercles anteriorly, anterior to them a pair of widely diverging processes, with sharply in-turned and hooked tips; scutellum submerged, not distinctly visible; elytra 1.10× longer than pronotum and 0.97× as long as its own width; basal margins truncated and somewhat weakly carinate; lateral sides substraight, but very weakly diverging posteriorly; postero-lateral margins feebly carinate and confluent with interstria 9; striae strongly impressed on disc, with elongate confluent punctures; interstriae 1, 3, 5 and 7 gradually distinctly ridged posteriorly and each terminating into a spine with a few tufts of long hairs at commencement of declivity; interstrial surface reticulate with small irregular punctures; declivity rather abrupt with uneven face; striae impressed and obsolete at middle of declivity; striae 1 and 2 confluent, 4 and 5 forming loop, 3 and 6 running up to posterior half of declivity; interstriae 1 and 3 strongly ridged, terminating slightly above the posterior margin, forming a blunt projection; interstria 2 obsolete, 4 depressed and narrowed, 5 broad; interstrial surface with fine, irregular granules; color blackish brown; body length: 3.09 mm , 2.06× as long as wide.
