( Figure 21 )

This species is diagnosed by the following morphological characters: ♂ frons surface shiny with rather dense uniform punctures, and a small fovea in the center; vertex with smaller, less dense punctures and median longitudinal black line (sulcus); long, sparse, yellowish hair-like setae more longer at the lateral sides of frontal area; epistoma with long dense yellowish setae directed downwards; eyes rather large, emarginate anteriorly, funicle five-segmented, club obliquely truncate with recurved sutures on anterior face, and one suture on apical posterior face; pronotum slightly longer than wide; sides sub parallel in basal three fourth, rounded towards apex; pronotal surface mostly granulate, without reticulation, coarser anteriorly; punctures on small area on central portion of pronotal base around short impunctate median line; lateral and anterior margin of pronotum with long, curved, yellow hair-like setae; scutellum, tongue-shaped, flat, reddish- brown; elytra slightly wider than pronotum, slightly more so towards apex; elytra coarsely punctured on disc, especially on striae 1–3; juxtasutural stria not impressed on disc and declivity, punctures on striae 1 st and 2 nd deep, large up to the commencement of declivity; interstriae in central part of disc narrow, 1.6–2.0× narrower than striae, minute punctures in one irregular row on each interstria; rather convex and shining; declivity slightly flattened, convex, not steep, dull; ventro-lateral sides of declivity not armed and without minute tubercles on declivital surface; 1 st and 2 nd interstriae widened at declivity, punctures on 1 st and 2 nd striae larger than punctures on other striae on declivity; 1 st and 2 nd striae slightly divergent towards elytral apex; elytral interstriae with rather long yellow hair-like setae, longer laterally and on declivity; short recumbent hair-like setae on striae; body length: 5.1 mm.

Female similar to male, except that the frons has a dense tuft of long yellow hair-like setae.

Remarks: This species differs from all other Indian species of the genus Dryocoetes by the exceptionally large punctures of the elytral discal striae and the large size of the body.
