( Figures 10–12 View Figures 6–12 )

Male. Integument black, except anteclypeus reddish-brown. Pubescence fulvous, except grayish-white pubescence, partially on basal half of antennomere IV, and base of antennomeres V-XI.

Head vermiculate between inferior eye lobes, coarsely from inferior ocular edge toward clypeus; pubescence on this area sparser, not forming patches. Pubescence between antennal tubercles and pronotal edge, and behind eyes dense, forming distinct irregular patches interspersed by glabrous or nearly so areas (larger behind eyes). Genae as long as 0.6 times length of inferior eye lobe in frontal view; pubescence forming, at most, sparse spot below posterior ocular edge, distinctly sparser on remaining area; moderately coarsely, abundantly punctate below inferior eye lobe, sparser, shallower toward ventral surface. Clypeus sparse punctate; pubescence sparse, slightly denser close to the distal margin; laterally with some long setae. Labrum with sparse pubescence; laterally with some very long setae; anterior edge with brush of long setae. Antennal tubercles narrowly separated, with distinct prominent tubercle as small horn with rounded apex. Mandibular basal half coarsely, abundantly punctate, with sparse pubescence. Antennae as long as 1.9 times elytra, reaching elytral apex at antennomere VIII. Antennal formula based on antennomere III: scape = 0.91; pedicel = 0.13; IV = 0.63; V = 0.47; VI = 0.43; VII = 0.41; VIII = 0.39; IX = 0.37; X = 0.41; XI = 0.43.

Prothorax slightly conical, wider at base, 1.4 times as wide as long; without distinct lateral tubercle. Pronotum with five tubercles: one laterally at each side of middle; one laterally, smaller and more internal than anterior ones, placed on distal half; one elongate at middle, from near base to distal third; area between lateral tubercles and distal edge with sparse, shallow, coarse punctures; area between anterior basal edge and lateral tubercles with small, moderately abundant rounded tubercles; area between median tubercle and behind larger lateral tubercle with deep sulcus; pubescence forming irregular spots, mixed by sparse, long setae. Lateral and distal margins of scutellum surrounded by wide band of pubescence, interrupted at middle of distal margin. Elytral basal third with longitudinal, wide, slightly elevate gibbous on each side of scutellum, covered with coarse granules; area between gibbosity and humerus with sparser, smaller granules; punctation coarse, deep, moderately abundant on basal third (mainly on outer side of gibbosities), becoming sparser, finer toward apex (area below humerus punctate-granulate); humeri prominent, anterior margin oblique, angle tuberculate; pubescence forming cross-like between scutellum and apex, band on each side of scutellum, band laterally on distal third, and irregular spots about middle sides. Ventral side of meso- and metathorax pubescent, mixed by glabrous areas, and small rounded areas with distinctly sparser pubescence.

Ventrites pubescent, mainly laterally, mixed by moderately abundant small, rounded, contrasting areas with distinctly sparser pubescence; on each side of ventrites I-IV with large area of pubescence as in the small rounded areas. Femora pubescent, mainly metafemora. Tibiae pubescent; protibiae distinctly arched.

Dimensions in mm. Total length, 27.3; prothoracic length, 5.2; largest prothoracic width, 7.2; humeral width, 11.6; elytral length, 18.4.
