( Figure 22)

This species is diagnosed by the following morphological characters: ♂ head globose; frons plano-convex, transversely impressed above epistoma; surface glabrous with scattered minute granules and long hairs, granules denser towards epistomal margin; epistomal margin with a fringe of long, golden hairs; eyes elongate with a shallow, wide emargination anteriorly; antennal club with two recurved sutures on anterior face; pronotum 1.10× longer than broad; sides sub-parallel on basal half, then gradually narrowing anteriorly, anterior margin broadly rounded; apical half finely and closely asperate and extending laterally up to base; rest of the basal half densely and coarsely punctured; hairs distinct anteriorly and postero-laterally; scutellum pear shaped, smooth and black; elytra 1.32× as long as pronotum and 1.51× as long as wide, sides parallel upto the commencement of declivity; elytral disc shiny; striae distinct marked with fairly large, shallow punctures running almost to the elytral end; punctures devoid of any distinct hairs; interstriae shiny, with widely spaced minute punctures and scattered long hairs, nearly as wide as striae; striae 1 and 2 rather impressed on elytra and within declivity, striae 1 to 3 running up to posterior margin; interstriae 1 to 3 also prominent up to the tip; interstriae 4 and 5 terminated at the commencement of declivity; declivity commencing on posterior fourth; declivital face stiff marked with interstrial setose granules, hairs longer on declivity and lateral sides of elytra; declivital margin not so demarcated but somewhat marked by slightly swollen interstriae 1 to 3; body dark redish-brown; body length: 2.70–2.81 mm, 2.61× as long as wide.

The 1 st stria is strongly deepened on the disc and declivity, more evident in males of this species, though it is also developed in the females.

Remarks: This species differs from D. indicus Stebbing, 1914 due to its much smaller body size and the strongly impressed first and second striae on the disc and declivity.
