<paragraph pageId="21" pageNumber="22">Body form relatively stout, relatively smaller species within subgenus, body length 9.5-10.5 mm; dorsal side blackish, moderately shining, elytron without iridescent shine; mouthparts, antenna, tarsus, and apex of tibia reddish brown; ventral side blackish. Both sexes with similar elytral microsculpture, isodiametric on disc, gradually turned to transverse on elytral apex and outer intervals. Head. Frons without punctures; antenna reaching elytron basal sixth; gena approx same length as eye, briefly tumid behind eye. Pronotum approx quadrate, lateral margin weakly curved, widest approx in middle; posterior margin a little narrower than anterior margin; PW/PL = 1.20-1.21; one mid-lateral seta present, a little before middle; posterior seta close to but a little distant from hind angle, distance between seta and hind angle much shorter than distance between hind angle and inner basal foveal groove; hind angle forming indistinct obtuse angle (Fig. 104); basal fovea shallow, faintly defined; inner groove subparallel to median line, basal half oblique outwards; outer groove indistinct but present, close to hind angle, approx one fourth length of inner one, outer area of inner groove slightly convex; basal foveal area almost impunctate. Elytron oviform, with basal ridge slightly curved; elytral shoulder moderately widened, shoulder angle between basal ridge and lateral margin completely rounded, humeral tooth absent; intervals feebly convex; striae moderately deep, faintly punctate before middle; scutellar stria short, apex free; 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, 1-2, 8-9). Ventral side. Proepisternum impunctate, mesepisternum and metepisternum impunctate; terminal sternum of male strongly concave in middle, concavity occupying four fifths length of terminal sternum, border of concavity carinate at anterior half, apex of terminal sternum flat. (Fig. 124). 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 metatarsomere superficial. Male genitalia. Median lobe of male genitalia bent less than 90 degrees, apex gradually bent ventrally (Fig. 43A); ventral margin evenly curved in middle, turned ventrally near apex; apical orifice large, slightly turned to left side, largely opened on ventral side; in lateral view, apical lamella very short, slightly twisted, laminate, a little thickened, its length approx one eighth length of apical orifice; in dorsal view, apical lamella short and wide, located on right side of aedeagal apex, pointing apically, length approx 0.8 times its basal width, apex rounded (Fig. 43B). Right paramere straight and stout, apical half slightly enlarged, length approx 2.5 times greatest width, apex rounded (Fig. 43C). Endophallus (Fig. 43D, E, F) bent to ventral side across left side of aedeagus, major portion of endophallus located on ventral side of aedeagus (in lateral view); gonopore (gp, gonopore lobe folded in Fig. 43) located at level much before apical lamella, pointing to right side. Six distinct lobes recognized: basal lobe (bl) small, close to apical lamella, decorated with very fine scales; right lobe (rl) small and compressed, decorated with fine spines near apex; left lobe I (lf-I) largest, basal half decorated with fine scales, apex coniform and well chitinized; left lobe II (lf-II) long and coniform, apex chitinized; ventral lobe (vl) long and slender, covered by lf-I, apex sharp, strongly prolonged and bent, its upper surface chitinized; pre-apical lobe (pa) just before gp, small and coniform, apex clearly chitinized. Besides those six lobes, a patch present close to gp, decorated with dense spines. Female genitalia. Spermatheca with seminal canal approx four times as long as receptaculum; receptaculum tubiform (Fig. 66), apical half slightly clavate; seminal canal inserted at base of common oviduct, base of seminal canal sclerotized. Stylomere II with two ensiform setae at outer margin, and one near middle of inner margin; two very short nematiform setae located in a furrow near apex. Female sternum VIII (Fig. 82B) with dense spines on posterior margin; posterior margin almost straight, slightly notched in middle; posterior region chitinized, anterior region semi-chitinized, without denser pigmentation, deeply notched in middle; middle transparent region V-shaped, adjacent to posterior notch but not to anterior notch in middle. Female tergum VIII (Fig. 82A) with major portion semi-chitinized, sparsely pigmented with irregular small spots, only lateral-anterior region with two chitinized patches; anterior margin deeply notched in middle.</paragraph>
