Measurements (n=20): HW: 0.70−0.75; HL: 0.40−0.50; OL: 0.23−0.25; AL (holotype): 1.44; PL: 0.65−0.70; PW: 1.10−1.19; ElL: 1.73−2.00; EW: 1.35−1.55; AedL: 0.67−0.71; TL: 2.97−3.80 (holotype: 3.20). Body and legs yellowish brown to reddish brown or brown, antennomere 1−4 (or 1−5), mouthparts, lateral margins of pronotum, lateral and apical margins of elytra and sometimes legs yellow; each elytron with yellow elongated spot, extending diagonally from midlateral portion to second longitudinal row of punctures from sutural margin in apical third of elytron. Dorsal surface of body shiny, without microsculpture except clypeus with tender and irregular transverse lines. Head (except clypeus) with irregular small deep punctation slightly denser on infraorbital ridges and between ocelli; disc of pronotum with very large and deep variably spaced punctation on middle elevation and with more or less finer punctation along posterior pronotal margin, lateral sides of pronotum with sparse, large irregular punctation; scutellum with a few punctures; punctation of elytra dense, somewhat larger and deeper than that on pronotum, disc of each elytron represented by more or less distinct six to seven longitudinal rows of serial punctures becoming not serially arranged toward basal and apical portions of elytron, punctures in apical portion of elytra visibly smaller. Habitus as in Fig. 5. Head 1.5−1.7 times as wide as long; clypeus moderately smooth, vertex slightly elevated with distinct or indistinct semicircular impression in front of ocelli, infraorbital ridges slightly impressed between posteriolateral margins of each eye and ocellus; eyes large and markedly convex; small and obtuse postocular ridge situated close to posterior margin of eye, distance about one fourth of length of eye seen from above; ocelli large, almost on one level with postocular ridges, distance between ocelli twice as long as distance between ocellus and posterior margin of eye. Antenna reaching one-third of elytral length when reclined; measurements of antennomeres (length/width, holotype): 1: 0.17 × 0.07; 2: 0.12 × 0.05; 3: 0.15 × 0.03; 4: 0.15 × 0.05; 5: 0.14 × 0.05; 6: 0.13 × 0.05; 7: 0.12 × 0.05; 8: 0.10 × 0.05; 9: 0.10 × 0.06; 10: 0.10 × 0.07; 11: 0.16 × 0.07. Pronotum transverse, 1.6−1.7 times as wide as long, 1.5 times as wide as head; apical margin slightly narrower than posterior margin, sinuately emarginated; anterior angles moderately widely rounded, lateral margins with uniform small crenulations, slightly more narrowed posteriad than anteriad, with obtuse posterior angles; disc of pronotum with wide middle elevation with distinct median longitudinal impression and with semicircular wide impression in basal third; lateral portions of pronotum slightly reflexed, each with deep pit at middle. Elytra elongate, convex, 1.5−1.6 times as long as wide; surface of each elytron with three very indistinct longitudinal elevations laterad of 3rd longitudinal row of punctures, more visible in basal third. Male. First four protarsomeres slightly dilated. Front tibia vaguely dilated at about middle in lateral view. Apical margin of abdominal tergite VIII almost straight (Fig. 11), that of sternite VIII vaguely, widely sinuate (Fig. 17). Median lobe of aedeagus (Fig. 26) gradually widened toward apical third and then narrowed toward rounded apex; parameres exceeding apex of median lobe, each with obtuse apical portion and with large, acute triangular projection on each lateral side at about middle; internal sac occupying more than half of length of aedoeagus (Fig. 27), with large, long U-shaped sclerite consisting of numerous elongate thorns. Aedeagus laterally as in Fig. 28. Female. First four protarsomeres not dilated. Front tibia simple, without modification. Apical margins of abdominal tergite VIII (Fig. 46) and sternite VIII (Fig. 53) rounded. Genital segment as in Fig. 60. Differential diagnosis. Based on the shape of lateral margins of pronotum with uniform crenulation, the character of punctation of elytra, body size and the general shape of the aedeagus, the new species is most similar to Taiwanese D. chiangi, from which it differs by the narrower body, coloration of elytra, by the pronotum gradually narrowed posteriad and with slightly denser lateral crenulation, by the longer elytra with three very indistinct longitudinal elevations in basal third and by the longer parameres, each with with triangular lateral projection. Similar, but less acute lateral dilatation of each paramere is characteristic for the Nepalese, not closely related D. egregium (Smetana 1985a: Fig. 88). Distribution. The new species is known from several locations (Fig. 65) in the Emei Shan range (Fig. 66) in Sichuan, China. Bionomics. All specimens were taken by sifting forest floor litter at elevations from 1729 to 2440 m a.s.l. Etymology. The specific epithet is the Latin noun emeicola, - ae, m (the one who lives on Mt. Emei) in apposition.
