Diagnosis. Pronotum relatively short, 0.75–0.81 X as long as wide; anterior margin of prothorax in front of procoxa angulately projecting; mesosternum with apically rounded, cone-shaped protrusion directed anteriad (Fig. 77); protibia in female (Fig. 135) with dorsal contour evenly convex; mesotibia in male (Fig. 128) with subapical dorsal extension short, dentiform; ventrite 4 in male in middle with inconspicuous transverse row of suberect setae (Figs. 95–96); aedeagus with apical scoop of pedon (Fig. 156) pointed.
Description. Holotype, male. Body length: 2.30 mm. Coloration of dorsal surface coppery, sides and venter bronze, tarsi ferruginous.
Head (Fig. 114) short. Gena 0.66 x as long as width of head behind eyes. Vertex microreticulate, markedly rugose-punctate. Eyes dorsally contiguous in middle for 0.7 x their length. Ventral surface markedly transversely rugose, anteriorly near eye with few interspersed punctures.
Rostrum 1.64 x longer than mouthparts; sides subparallel to antennal insertion, anteriorly diverging until subapically rounded; at widest point 1.21 x wider than at base; dorsum above antennal insertions with weakly rounded prominence, anteriorly flat to apex. Clypeus medially with simple notch. Basal lateral groove distinct, ventrally curved, its convex side anteriorly; terminating at level of ventral eye margin. Venter basally without submental median carina. Submentum posteriorly microreticulate, anteriorly shining, with two long, stiff, suberect setae. Prementum at base 1.7 x wider than long, ca. 3.4 x wider than at apex; sides straight, converging apicad.
Antenna as in Fig. 121.
Proventriculus (Fig. 102) with eight primary folds bearing spiniform processes.
Thorax. Prothorax 0.76 x as long as wide; subbasal constriction laterally absent, dorsally shallow; sides converging in straight line to apex, without preapical constriction; anterior margin laterally in front of procoxa with collar-like extension abruptly truncated ventrally, angular in profile; disc markedly punctate-rugose, in basal half with transverse wrinkles concave, in apical half rather V-shaped; sides punctate; prepectus in lateral aspect as long as postpectus; mesosternum with apically rounded, cone-shaped protrusion directed anteriad. Height of pterothorax 0.85 x length of elytron.
Elytron 2.15 x longer than wide; intervals weakly shining, somewhat dull, with distinct coriarious sculpture of irregularly transverse wrinkles (Fig. 88).
Legs. Procoxa 0.89 x as long as wide; approaching anterior margin of prothorax; in anterior aspect coxae with inner contour diverging in convex line; anterior surface microreticulate, sparsely shallowly punctate. Protibia with dorsal contour evenly convex; uncus subventral. Mesotibia (Fig. 128) with subapical dorsal extension acute, subtriangularly dentiform.
Abdomen. Venter flat, surface medially sparsely punctate, sparsely setose with recumbent setae; ventrite 4 in middle with inconspicuous transverse row of suberect setae pointing backwards (Figs. 95–96). Pygidium 1.08 x wider than long.
Terminalia. Sternite VIII (Fig. 164) medially subdivided by membrane connecting lateral sclerotised areas; apex broadly bilobate, densely setose with long setae; base medially with marked constriction. Tegminal plate as in Fig. 157. Aedeagus with sclerotised sides of pedon widening mesoapicad, connected to subtriangular plate fused with its short side to apical scoop, the latter (Fig. 156) ca. 1.14 x longer than wide, sides sinuate and converging, apex pointed; tectum with sides converging, apically pointed; TA (Figs. 154–155) flagelliform, insertion of ductus ejaculatorius ventral; basal sclerite long, narrow, folded dorsoapicad, dorsally fitting to basal half of long, C-shaped flagellum formed by fusion of extended transferprocesses. Endophallus with cuticle densely minutely denticulate.
Female. As holotype except: Length 2.26 mm. Head as in Fig. 115. Gena 0.65 x as long as width of head behind eyes. Rostrum 1.69 x longer than mouthparts. Prothorax 0.75 x as long as wide. Elytron 2.14 x longer than wide. Protibia (Fig. 135) with dorsal contour evenly convex; ventral contour evenly sinuate; uncus median. Abdomen with venter flat. Pygidium 1.05 x wider than long. Sternite VIII as in Fig. 172. Spermatheca (Fig. 181) with body moderately tapering apicad.
Intraspecific variation. Size: length 1.68–2.30 mm (n=20, x =2.12 ± 0.17); prothorax 0.75–0.81 x as long as wide (n=20, x =0.77 ± 0.02);. elytron 2.00–2.21 x longer than wide (n=20, x =2.10 ± 0.05); height of pterothorax 0.83–0.92 x length of elytron (n=20, x =0.87 ± 0.02); abdomen with patch of modified setae in female 1.19–1.90 x longer than wide (n=10, x =1.39 ± 0.23); pygidium 0.89–1.08 x wider than long in males (n=10, x =0.98 ± 0.05), 0.94–1.07 x in females (n=10, x =1.02 ± 0.05). Coloration ranging from goldencoppery to greenish-bronze and bluish-bronze. Flagellum C-shaped (as in holotype) or S-shaped.
