Description of the holotype

Head. – Frons moderately abundantly, finely punctate; integument glabrous, dense yellowish-white pubescence close to lower eye lobes. Vertex moderately abundantly, finely punctate; with golden pubescence partially obscuring integument; with a few long, erect yellowish setae close to upper eye lobes. Area behind eyes glabrous, punctate. Genae with dense yellowish-white pubescence partially obscuring integument. Antennal tubercles with yellowish-white pubescence not obscuring integument. Median groove distinct from clypeus toprothoracic margin. Externalmargin of mandibles covered with dense yellowish pubescence obscuring integument, basal area with sparse long yellowish setae. Gulamentum glabrous. Distance between upper eye lobes 0.31 times length of scape; in frontal view, distance between lower eye lobes 0.90 times length of scape. Antennae 1.6 times elytral length, reaching elytral apex atantennomere VII; scape, pedicel and antennomeres III-X with long, erect sparse setae ventrally (shorter, sparser toward X).

Antennal formula (ratio) based on length of antennomere III:

– Scape = 0.88. – Pedicel = 0.18. – IV = 0.75. – V = 0.56. – VI = 0.44. – VII = 0.44. – VIII = 0.44. – IX = 0.31. – X = 0.25. – XI = 0.21.

Thorax. – Prothorax 1.2 times wider than long. Pronotum moderately abundantly and coarsely punctate; with golden pubescence nearly obscuring integument except yellowish-brown pubescence on dark area, not obscuring integument, more pale yellow centrally on basal area, and nearly glabrous on small central area before middle; with long, erect, sparse yellowish setae. Sides of prothorax with moderately sparse punctures slightly coarser than on pronotum; with golden pubescence not obscuring integument. Prosternum and mesoventrite with pale-yellow pubescence distinctly not obscuring integument (slightly denser, more golden laterally on mesoventrite); mesanepisternum, mesepimeron, metanepisternum, and sides of metaventrite with abundant, golden pubescence not obscuring integument; central area of metaventrite with golden pubescence distinctly sparser than laterally. Scutellum with yellowish pubescence obscuring integument.

Elytra . – Coarsely, abundantly punctate on basal 2/3, punctures slightly coarser dorsally close to humeral carina, nearly smooth on distal third; distal third with dense beige pubescence, except brownish pubescence close to lateral margin; erect setae more abundant on basal half.

Legs. –Femora ventrally with long,erect, sparse yellowishsetae interspersed.

Tibiae covered with dense yellowish pubescence not obscuring integument.

Abdomen. – Ventrites covered with yellowish-white pubescence not obscuring integument, and long, erect, sparse yellowish setae interspersed; apex of ventrite 5 truncate, centrally feebly emarginate.
