Diagnosis. Similar to D. honorus in habitus and morphology of male genitalia, differs from the latter in the following characters: 1) basal margin of penis shallowly concave (deeply concave in D. honorus); 2) parameroids moderately wide in apical portion (very wide in D. honorus); 3) strong punctation of elytra, punctures separated by ca. 0.3 diameter (in D. honorus separated by ca. 0.5 diameter).
Description. Male. Body oval, slightly convex dorsally, strongly shining, closely covered with easily removable setae throughout. Coloration of body black; head, mouthparts, antennae, pronotum, scutellum, humeral and apical part of elytra, forelegs, middle and hind tibiae and tarsi yellowish-orange.
Head moderate in size, finely punctate, slightly convex dorsally; distance between eyes about 1.9 times as long as maximum diameter of eye. Eyes moderate in size, slightly prominent. Pronotum transverse, strongly depressed in lateral parts, finely punctate; anterior margin almost straight; anterolateral angles obtuse, slightly projecting anteriorly; lateral and posterior margins gently arcuate; posterolateral angles about 90°; PW/PL 2.26–2.88 (2.51). Scutellum small, equilateral-triangular, finely punctate. Elytra oval, widest at middle, closely punctate, gently arcuate at lateral margins; shoulder parts slightly elevated; EL/EW 1.26–1.33 (1.29); EL/PL 5.19–6.38 (5.67); EW/PW 1.73–1.81 (1.76); TL/EW 1.48–1.58 (1.52). Legs relatively short.
Caudal margin of sternite VII arcuate. Sternite IX (L 0.18 mm, W 0.25 mm) moderately sclerotized, semicircular, bearing long setae and short spines in apical portion; tergite VIII (L 0.34 mm, W 0.35 mm) moderately sclerotized, transversely trapezoidal, bearing short spines at mesal portion of posterior margin, and short setae in posterolateral portions, with a pair of short apodemes; tergite IX (L 0.33 mm, W 0.22 mm) slightly sclerotized, with a pair of long apodemes. Tegmen short (L 0.18 mm, W 0.16 mm), slightly sclerotized; parameres short, obtuse at apices; lateral projections long (L 0.34 mm), pointed at apices. Penis (L 0.47 mm, W 0.12 mm) moderately sclerotized, widest at basal 1/4; pala oval, shallowly concave at basal margin; parameroids long, slender, closely punctate; trigonium short, triangular, shallowly concave at apex.
Female. Unknown.
Measurements. Male (n = 3): TL 2.95–3.28 mm (3.15 mm); PW 1.15–1.20 mm (1.18 mm); PL 0.40–0.53 mm (0.48 mm); EW 2.00– 2.17 mm (2.08 mm); EL 2.55–2.75 mm (2.68 mm).
Etymology. This species is named after Dr. Tatsuya Niisato, Bioindicator Co., Ltd., Tokyo, who gave the second author a specimen of this species.
Distribution. Laos.
