Description. Measurements. Length: 4.4–5.4 mm; width across humeral calli: 0.7–0.9 mm; ratios: length of head/ length of pronotum: 0.7–0.9; length of pronotum/width of pronotum: 1.3–1.4; base of pronotum/apex of pronotum: 1.4–1.6; length of pronotum/length of elytra: 0.40–0.45; length of elytra/width of elytra: 3.1–3.3. — Colour. Head, antennae and pronotum brownish-red; legs and elytra paler. Elytra with darker sutural stripe and transverse post-median blotch. — Habitus. Figs 7–8 View Figs 1–8 . — Head ( Fig. 41 View Figs 34–50 ) strongly broader than long, finely punctate, with small basal median notch. Eyes large, projecting laterally; temples short not protruding behind eyes. Vertex and frons shallowly grooved. Metarostrum, mesorostrum and base of prorostrum longitudinally grooved, metarostrum without lateral grooves. Prorostrum with very fine punctures, 0.5–0.7× as long as head + metarostrum + mesorostrum. Antennal segment 3 ( Fig. 42 View Figs 34–50 ) broader than long, conical; 4–8 subglobular, broader than long, with a row of long raised setae; 9–11 slightly flattened, 11th 1.6–2.0× longer than 10th. Venter of head, metarostrum and mesorostrum longitudinally grooved; mesorostrum with small projection on either side under antennal base. — Pronotum ( Fig. 41 View Figs 34–50 ) flattened, almost depressed on disc, longitudinally grooved, much broader at base than at apex, with numerous fine punctures. Prothorax without fovea in front of quite rounded, hardly conical procoxae; prosternellum distinct. Protibiae ( Fig. 43 View Figs 34–50 ) 0.5–0.6× as long as profemora. Metasternum longitudinally grooved, laterally not carinate, punctate (especially on lateral declivities). Elytra glabrous, base straight. Interstria 2 present from base to apex; 3 more elevated and present from base to apex; 4 present from base to apical declivity; 5, 6 and 7 fused anteriorly to form a common humeral callus; 8 present only on 2nd half of elytra; 9 forming external apical border of elytra. Apex of elytra not explanate nor notched at apex. Hind wings ( Fig. 50 View Figs 34–50 ) without basal sclerite.

Sternites III–IV ( Fig. 44 View Figs 34–50 ) slightly grooved and punctate, laterally not carinate, weakly depressed in male; V–VI finely punctate posteriorly; VII with transverse median notch at base and two latero-apical depressions, without apical fovea, in male with two rows of raised setae between latero-apical depressions. Spiculum gastrale as in Fig. 45 View Figs 34–50 . Tegmen ( Fig. 46 View Figs 34–50 ) with parameres reduced, filiform, short, not fused. Tergite VIII of female ( Fig. 47 View Figs 34–50 ) bluntly denticulate at apex. Spermatheca as in Fig. 48 View Figs 34–50 . Gonocoxites ( Fig. 49 View Figs 34–50 ) fused at base; styli reduced, lateral.
