Description (holotype). Length. 7.4 mm (from apical margin of the pronotum to apices of elytra).
Male. Body elliptical, convex dorsally, broad, about 1.84 times as long as wide excluding head. Color brown, but head whitish, apical half of pronotum and lateral margin of pronotum formed by white hairs and white lines, three tufts of elytra orange, and with white patches at apex of elytral suture and at basal 1/3 of 7th interval. Femora each reddish brown; tibiae each brown but two orange rings: one situated at middle and another one situated around apex; tarsi with apical half brownish.
Head rectangular, about 1.23 times as long as wide, nearly flatted dorsally, densely covered with white hairs; interocular width about 0.70 times as broad as interscrobal width; eyes as long as broad; rostrum parallel-sided, closely covered with white fine hairs. Antennae reaching to posterior margin of pronotum, basal two segments ovate, 1st a little longer than 2nd, 3rd the longest, 4th longer than 5th, 6th the shortest which is nearly as long as 7th and 8th, club symmetrical, 9th triangular, apically dilated, about 1.68 times as long as wide, 10th a little shorter than 11th which is as long as 9th.
Pronotum trapezoidal and convex dorsally, about 1.85 times as long as wide, narrowed anteriorly; with tubercle near postero-lateral angle of lateral margin; disc with two tufts, in front of the two tufts a transverse line, from each end of which a similar line runs obliquely forward to the other side of the disc without reaching apical margin, a median line from apical margin to transverse line, all four lines white, unclearly marked and fixed-width; three pairs of whitish patch along posterior margin. Scutellum small, clothed with brown hair.
Elytra convex dorsally, about 1.25 times as long as wide, parallel-sided in basal half, then narrowed posteriorly, basal margin rounded and apices rounded; with three pairs of tufts: 1st pair large, oblong-oval in dorsal view, roundly convex in lateral view, situated at basal 1/4 of 3rd interval; 2nd and 3rd pairs small, rounded in dorsal view, each pair situated at apical 1/4 of 3rd interval, 5th interval. Pygidium nearly rectangular, about 0.54 times as long as wide, uniformly brown; basal margin strongly emarginate at the middle, lateral margins almost straight.
Prosternum distinctly covered with whitish hairs; metaventrite sparsely punctate, the punctures larger than those on prosternum, and distinctly covered with whitish hairs which are regularly decumbent. Ventrites covered with small punctures which are sparser and shallower than those of metaventrite, and with white finer hair than on metaventrite; viewed from side, ventrite 1–4 almost horizontal conjointly, ventrite 5 somewhat slanting; ventrite 5 margined in the middle, and having two brownish patches of hair.
Female. Unknown.
Type material. Holotype: ♂, Lienhuachih , Taiwan, 25 VI 1971, K. Kojima leg.
Distribution. ( Fig. 11 View FIGURE 11 ) Taiwan.
Etymology. The specific name is in honor of the late Dr. Keizo Kojima who collected the holotype of this new species.
Comments. In general appearance, this species is similar to D. decoratus Jordan, 1928 from Luzon in that the median line of the pronotum reaches the transverse line, but can be distinguished from the latter by the following characteristics: tufts of elytral disc small, not dark ferruginous but orange, head with whitish hair, and the mark of white lines on anterior half of pronotum unclear.
