Elytra dark reddish brown laterally, gradually lighter toward apex. Pro- and mesofemoral peduncle dark reddish brown; tibiae dark reddish brown basally (browner depending on light intensity), gradually dark brown toward apex. Apex of ventrite 5 mostly yellowish brown.

Head. – Frons coarsely rugose-punctate; inclined laterally from antennal tubercles to clypeus, forming deep fovea close to clypeus; with triangular, large, frontal plate at same level of postclypeus; with narrow sulcus on each side close to frontal plate, fused centrally and following toward vertex; with abundant golden pubescence centrally and close to eyes, not obscuring integument, sparser on remaining surface, and somewhat abundant, long, erect golden setae interspersed. Area between antennal tubercles and upper eye lobes somewhat shallowly rugose; with dense golden pubescence, except some irregular areas laterally with sparser pubescence, and almost glabrous area of median groove; with a few long, erect golden setae interspersed laterally. Remaining surface of vertex finely rugose-punctate, with moderately sparse golden pubescence. Area behind upper eye lobes finely rugose-punctate; with abundant golden pubescence close to eye, except glabrous area close to connection between eye lobes; remaining surface with somewhat sparse golden pubescence; with a few long, erect golden setae interspersed close to eye. Area behind lower eye lobes slightly tumid, coarsely rugose-punctate close to eye, more striate-punctate close to prothorax, especially toward ventral surface; with sparse, short, bristly golden setae, denser toward ventral surface, and long, erect setae of same color interspersed on tumid area, almost glabrous on remaining surface. Genae with punctate and smooth areas; with abundant golden pubescence not obscuring integument toward apex, absent on smooth area, and long, erect setae of same color interspersed. Wide central area of postclypeus abundantly, somewhat coarsely rugose-punctate close to frons, smooth close to anteclypeus; with bristly golden setae close to frons, glabrous close to anteclypeus; with long, erect setae of same color interspersed. Sides of postclypeus smooth, glabrous. Labrum with small irregular, asperate protuberance on each side with abundant, long, erect golden setae; remaining surface glabrous, except fringe of moderately long golden setae directed forward close to anterior margin. Distance between upper eye lobes 0.41 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.61 times distance between outer margins of eyes. Antennae 1.2 times elytral length, reaching posterior sixth of elytra. Scape coarsely rugose-punctate; with abundant golden pubescence not obscuring integument dorsally and laterally, pubescence absent ventrally, and moderately abundant, long, erect, both brown and yellowish setae interspersed throughout. Pedicel somewhat abundantly, finely rugose-punctate; with abundant golden pubescence on wide central area, very sparse on remaining surface; with long, erect golden setae throughout. Antennomeres III–IV with abundant golden pubescence not obscuring integument dorsally except glabrous apex, very sparse on remaining surface; with long, erect golden setae interspersed throughout, part of

apical setae darker. Antennomeres V–XI with abundant dark pubescence, some antennomeres with sparse, minute yellowish setae interspersed, and a few short, erect brownish setae apically dorsally and/ or ventrally.

Antennal formula based on length of antennomere III:

– Scape = 0.95. – Pedicel = 0.48. – IV = 0.91. – V = 0.91. – VI = 0.87. – VII = 0.98. – VIII = 0.87. – IX = 0.82. – X = 0.82. – XI = 0.91.

Thorax. – Prothorax slightly wider than long. Pronotum shallowly rugose-punctate, sculpturing coarser laterally, except smooth, innermost lateral tubercles and central tubercle; outermost lateral tubercles strongly elevated, conical; innermost lateral tubercles transverse, slightly elevated, with rounded apex; central tubercle longitudinal, slightly elevated, narrow anteriorly, less elevated and widened posteriorly, located from about middle to posterior constriction; with abundant golden pubescence, sparser laterally, absent on center of anterior third, innermost lateral tubercles, central tubercle, and anterior longitudinal carina, forming dense tuft directed lateraly on top of outermost lateral tubercles; with long, erect golden setae interspersed. Sides of prothorax densely rugose-punctate;with sparse golden pubescence, more abundant near anterior and posterior margins, with long, erect setae interspersed anteriorly and posteriorly. Prosternum somewhat coarsely, transversely striate-punctate on anterior quarter; posterior 3/4 with sparse golden pubescence, denser close to anterior quarter; anterior quarter with a few, both short and long golden setae. Prosternal process with dense, bristly golden pubescence basally, almost glabrous on remaining surface; narrowest area 0.11 times procoxal width. Mesoventrite sparsely, finely punctate;with a few long, decumbent golden setae. Mesanepisternum witha few short, decumbent golden setae, except dense, bristly golden pubescence on outer side; mesepimeron almost glabrous. Mesoventral process gradually narrowed toward apex; somewhat abruptly inclined basally, longitudinally sulcate toward apex; apex inclined toward body surface; with a few short, bristly golden setae centrally. Metanepisternum with dense golden pubescence basally and on posterior half, pubescence sparse on remaining surface. Metaventrite somewhat abundantly, finely punctate laterally, punctures gradually sparser toward metathoracic discrimen; with dense golden pubescence on sides of posterior half, not reaching metacoxal cavities, somewhat abundant on remaining surface, except denser oblique band from area with dense pubescence to intercoxal process, and glabrous posterocentral area; with long, erect setae of same color interspersed. Scutellum with golden pubescence centrally, pubescence denser on anterior quarter of this area, glabrous laterally.

Elytra. – With dense yellowish-white pubescence, and abundant, irregular glabrous areas, irregular areas with sparse brownish pubescence, and irregular areas with golden pubescence interspersed, except center of anterior depressed area and irregular macula on

posterior third of dorsal surface with dense blackish pubescence; with long, erect golden setae interspersed throughout.

Legs. – Femoral peduncle with sparse, decumbent yellowish-brown setae dorsally and laterally, and somewhat abundant, both short and long pale-yellow setae ventrally; dorsal surface, most of inner surface, and superior area of inner surface of femoral club with dense yellowish-brown pubescence on wide central area, slightly sparser on inner surface, sparser basally and apically, with short, erect, dark-brown setae interspersed basally on dorsal surface, and long, erect yellowish-brown setae interspersed apically on dorsal surface; remaining surface of femoral club with sparse yellowish-brown setae, and long, erect setae of same color interspersed. Tibiae with dense yellow pubescence on dorsal base, somewhat abundant, both short, decumbent and long, erect yellowish-brown setae dorsally and laterally, and short, erect dark yellowish-brown setae ventrally, more abundant toward apex. Metatarsomere I slightly longer than II–III together.
