<paragraph pageId="7" pageNumber="8">Body form relatively stout, body length 9.9-11.1 mm; dorsal side black, shining; elytron with faint iridescent shine; mouthparts, antenna and tarsus yellowish brown; ventral side almost black. Both sexes with similar elytral microsculpture, very faint and linear. Head. Frons without punctures; antenna reaching elytron basal fifth; gena approx same length as eye, briefly tumid behind eye. Pronotum round, widest before middle, PW/PL = 1.21-1.32; usually four (sometimes three) mid-lateral setae present, first one close to anterior angle, last one near middle of lateral margin, a little distant from other three; posterior seta far distant from hind angle, distance between seta and hind angle approx same as distance between hind angle and inner basal foveal groove; hind angle completely rounded; basal fovea shallow, faintly defined; inner groove subparallel to median line, slightly curved outwards; outer groove completely vanished, outer area of inner groove flat; basal foveal area usually impunctate, sometimes with very sparse punctures on inner area of inner groove. Elytron oviform, basal ridge slightly oblique; elytral shoulder slightly narrowed, basal ridge and lateral margin forming obtuse angle, humeral tooth indistinct; intervals feebly convex; striae moderately deep, without punctures; scutellar stria short but complete; third interval with two setigerous pores adjacent to second stria; umbilical pore series on ninth interval sparse in middle, composed of 15-16 pores (6, 1, 8-9). Ventral side. Proepisternum impunctate or slightly punctate near posterior margin; mesepisternum densely punctate; metepisternum impunctate; terminal or penultimate sternum of males not modified. Legs. Fifth tarsomeres glabrous beneath; males with apical half of mesotibia slightly widened, inner margin slightly crenulate; first metatarsomere with distinct carina on outer surface, such carina on second and third metatarsomeres superficial. Male genitalia. Median lobe of aedeagus bent approx 90 degrees, apex slightly bent ventrally (Fig. 34A); ventral margin straight in middle, dorsal margin gradually curved; apical orifice large, slightly turned to left side, not opened on ventral side; apical lamella short, approx one fourth length of apical orifice, laminate, not thickened; in dorsal view, apical lamella located at middle of aedeagal apex, approx triangular with rounded apex, wide and short, length approx equal to basal width (Fig. 34B). Right paramere straight and slender, length approx 3.5 times greatest width, apex rounded (Fig. 34C). Endophallus (Fig. 34D, E, F) short, bent to ventral side, across apical lamella, and then turned to aedeagal base; gonopore (gp) located at approx same level as apical lamella. Six distinct lobes recognized: ventral-basal lobe I (vb-I) very small, close to base of apical lamella, membranous with its upper surface scaled; ventral-basal lobe II (vb-II) large and strongly chitinized, arcuate, strongly pointed, its upper surface with a membranous structure connected with vb-III; ventral-basal lobe III (vb-III) small, rounded with apex pointed, located on left side of vb-II, evenly decorated with very fine scales; ventral-apical lobe (va) short and wide, almost covered by vb-II, heavily pigmented, decorated with coarse scales, located on right side of vb-II; pre-apical lobe (pa) narrow and long, tubiform, without decoration, located on right lateral side; right lobe (rl) large, much thicker and a little longer than pa in ventral view, apex truncate, evenly decorated with fine scales. Female genitalia. Spermatheca (Fig. 53) with seminal canal approx three times as long as receptaculum; receptaculum capitate, club approx half length of receptaculum; spermathecal gland slightly expanded; seminal canal inserted at base of common oviduct, base of seminal canal sclerotized. Stylomere II with two ensiform setae at outer margin and one at middle of inner margin, two very short nematiform setae located in furrow near the apex. Female sternum VIII (Fig. 71B) with dense and fine spines on posterior margin; posterior margin rounded, shallowly notched in middle; posterior region chitinized, anterior region semi-chitinized, middle transparent region V-shaped, not adjacent to posterior notch in middle. Female tergum VIII (Fig. 71A) with anterior third well chitinized, posterior two thirds semi-chitinized and pigmented with dense spots.</paragraph>
