Redescription. Male. EBL: 5.59 mm. Length of different body parts: HL: AL: PL: ELL = 0.89: 2.59: 1.23: 3.14 mm; width: HW: EW: PW: ELW = 1.02: 0.07: 1.75: 2.50 mm. Proportion of antennomeres from base to tip in µm (length × width): 224 × 116, 215 × 93, 272 × 105, 233 × 98, 214 × 97, 193 × 105, 182 × 134, 146 × 108, 165 × 139, 162 × 148, 273 × 142.

Habitus ( Fig. 2C View FIGURE 2 ) elongate, not much convex and sublustrous; well pigmented: mostly brown; mouthparts, apical half of ultimate antennomere, and apical part of tarsi a little paler. Dorsum continually clothed with short, recumbent and sallow pubescence.

Head only slightly wider than long, HW/HL = 1.14. Surface covered with large and coarse punctures, separated about 1.0–2.0 times of their diameter, interspaces microreticulate. Clypeofrontal suture absent. Clypeus with substraight anterior margin. Compound eye built from ca. 57–62 ommatidia, EW/HW = 0.07. Antennae ( Fig. 15A View FIGURE 15 ) long and slender, AL/HW = 2.55; all antennomeres longer than wide; length of 3rd/2nd = 1.26; 11th elongate pear-shape. Cervical sclerite with length/width = 1.80 in medial view ( Fig. 4C View FIGURE 4 ).

Pronotum ( Fig. 15B View FIGURE 15 ) transverse, widest around middle, PW/PL = 1.43. Sides regularly narrowed forward from widest and gently constricted before hind corners. Hind corners rounded, slightly protruding backward. Posterior margin slightly bisinuate, slightly emarginate behind hind corners. Surface covered with fine punctures, interspaces smooth, with shallow depression in each latero-basal area.

Elytra oval, incompletely fused with each other, widest at about basal 2/5, ELL/EW = 1.26. Sides regularly curved, evenly narrowing from widest to apex; apices ( Fig. 15G View FIGURE 15 ) narrowly rounded. Sutural striae present. Surface covered with fine punctures, interspace smooth. Metathoracic wings absent.

Prolegs slender, with basal three protarsomeres ( Fig. 15C View FIGURE 15 ) faintly expanded: TW/BTW = 1.30. Protibiae ( Fig. View FIGURE 15

15E) almost simply and gradually expanded towards apex, without visible outer spines. Profemora without tubercle on inner side. Mesotibiae with inner margin slightly sinuate, 1 st mesotarsomere ( Fig. 7C View FIGURE 7 ) moderately expanded. Metatibiae straight.

Abdominal ventrite VIII ( Fig. 15I View FIGURE 15 ) with middle indentation at anterior edge, and narrowly emarginate at middle of posterior edge. Genital segment ( Fig. 15J View FIGURE 15 ) with slender spiculum gastrale, and never expanded dorsoventrally ( Fig. 15K View FIGURE 15 ); tergite IX rounded ventro-apically.

Aedeagus ( Fig. 16A, B View FIGURE 16 ) with median lobe large and wide (length/width = 5.25), slightly undulate and subequal above base, apex much wide and gently emarginate in dorsal view; parameres filiform, reached about apical 2/5 of median lobe, each with two apical setae; basal lama short; ventral operculum with two wide lobes, each acuminated to a sharp apex. In lateral view, median lobe fairly bent ventrad, gradually tapering towards a dorsally upturned apex ( Fig. 16C View FIGURE 16 ). Internal sac ( Fig. 16A–C View FIGURE 16 ) with a huge fan-like tooth at apex, a pair of spine clusters in middle region, and abundant toothlets in basal region.

Female. Somewhat chubbier and duller than male in general appearance ( Fig. 2D View FIGURE 2 ), and also can be distinguished from following characteristics: pro- & mesotarsi simply linear ( Fig. 15D View FIGURE 15 ); protibiae ( Fig. 15F View FIGURE 15 ) simply slender, furnished outer spines; elytral apices ( Fig. 15H View FIGURE 15 ) more acuminated, sutural angles weakly protruded; ventrite VII ( Fig. 17A View FIGURE 17 ) slightly emarginate at posterior edge; tergite VIII ( Fig. 17B View FIGURE 17 ) truncate in middle of posterior edge, desclerotized medioapically and laterally; ventrite VIII ( Fig. 17C View FIGURE 17 ) regularly rounded at posterior edge, spiculum ventrale rather wide; tergite IX ( Fig. 17D View FIGURE 17 ) rounded at posterior edge, with numerous setae posteriorly; ventral sclerite ( Fig. 17F View FIGURE 17 ) broad and shovel-like, regularly rounded at posterior edge, without sensillae; valvifer ( Fig. 17D, E View FIGURE 17 ) with 1 lateral seta; coxite ( Fig. 17D, E View FIGURE 17 ) with 3 subapical, 1 lateral and 1 basolateral setae and some much finer surface setae (some setae missing in the examined specimen; more details see Fig. 20 in Růžička, 1994); stylus minute ( Fig. 17D, E View FIGURE 17 ), cylindrical, with 1 long seta.
