Length: 8.5 mm (holotype); 8–10mm (paratypes)

General integument ( Figs 41, 42 ) dark or clear reddish-brown; legs clearer; antennae sometimes darker. Pubescence long, dense and yellowish, masking integument.

Frons ( Figs 2 , 41, 42 ) as long as wide, widened and strongly rounded anteriorly, surpassing frontoclypeal region; punctation moderately coarse and dense. Antenna ( Figs 1 , 42 ) narrow, subserrate with 11 antennomeres, surpassing hind angles of pronotum by two antennomeres in male; shorter in female; with longitudinal median carina in both sexes; 3rd antennomere slightly narrower at base and shorter than 4th.

Pronotum ( Figs 2 , 41, 42 ) as long as wide (including hind angles), narrowed and strongly convex anteriorly; lateral margins almost parallel on basal half; convexity decreasing basad; declivous between hind angles; punctation moderately coarse and dense, denser laterally; hind angles well developed, directed posteriorly and strongly carinate. Prosternum ( Figs 4 , 42 ) slightly convex, punctation coarse and sparse. Prosternal spine ( Figs 3, 4 ) flattened between procoxae and compressed laterally apicad; apex rounded with subapical spine directed ventrally. Pronotosternal sutures wide, prothoracic groove well developed. Mesosternal cavity ( Figs 3 , 42 ) Ushaped with borders slender and horizontal on basal half. Mesepimeron and mesepisternum forming part of margin of mesocoxal cavity. Metacoxal plate ( Fig. 5 ) moderately narrowed laterally; free margin with well developed rounded tooth. Tibial spurs very long. Tarsomeres 1–3 ( Fig. 42 ) lamellate beneath; lamella of tarsomere 3 longer than tarsomere 4. Scutellum ( Fig. 41 ) elongate, slightly narrowed apicad; distal margin rounded. Elytra ( Figs 41, 42 ) very convex, narrowed on distal third; striae marked by row of punctures; interstices flat; apex sharpened with tiny distal spine.

Male. Tergite VIII ( Fig. 8 ) as wide as long, round- and slightly narrowed apicad; translucent mediobasally; marginate by setae of varied sizes on distal 2/3. Sternite VIII ( Fig. 6 ) wider than long, band-like; fore angles rounded; translucent with one C-shaped yellowish band each side; long setae near each fore angle. Sternite IX ( Fig. 7 ) elongate, widened near middle, slightly narrowed apicad; setae moderately long on distal third. Tergite IX ( Fig. 9 ) wider than long, narrowed apicad; coarsely punctate laterally; distal margin deep- and narrowly V-shaped emarginated, forming a rounded lobe each side; long setae laterally near each fore angle. Tergite X elongate, gradually narrowed apicad; some setae irregularly distributed on distal third. Aedeagus ( Figs 10, 11 ) 2.5 times longer than wide; basal piece 0.8 times parameres (dorsally) length; apex of parameres cuneiform; cuneiform area almost straight laterally, with basal and distal angles rounded; a few long setae dorsal and several ventral of varied sizes; median lobe (excluding basal struts) shorter than parameres dorsally; slightly constricted at base and gradually narrowed apicad; wider area of median lobe wider than that of parameres (dorsally) at base.

Etymology. The specific epithet is a derivative of the Latin word modestus (=moderate) referring to the size of the specimens.
