Redescription. Male. Integument mostly dark brown; apex of maxillary and labial palpomeres yellowish brown; antennomeres IV–XI reddish brown on base, this area larger on ventral surface, brown on remaining surface.

Head. Frons densely, moderately coarsely punctate; with yellowish brown pubescence partially obscuring integument toward antennal tubercles, sparser distally, yellower, denser close to eyes; with short, suberect yellowish setae throughout, and long, erect yellowish setae close to lower eye lobes. Area between antennal tubercles and upper eye lobes with punctures as on frons, slightly sparser toward posterior margin of eyes, except sub-diamond central area nearly smooth; pubescence and setae as on basal area of frons except narrow band with dense pale yellow pubescence close to eyes; remaining surface of vertex moderately coarsely, sparsely punctate, with pubescence as on basal area of frons. Area behind eyes moderately coarsely, sparsely punctate (punctures slightly finer toward apex of lower eye lobes); with narrow pale yellow pubescent band close to upper eye lobe, gradually widened, paler toward inferior margin of lower eye lobe; remaining surface with yellowish brown pubescence gradually sparser toward inferior margin of lower eye lobe; with a few long, erect yellow setae close to eye. Antennal tubercles moderately finely, abundantly punctate on base of frontal area, densely micropunctate on remaining surface; with yellowish brown pubescence partially obscuring integument, with long, erect yellowish setae interspersed. Median groove distinct from clypeus to prothoracic margin. Genae finely, transversely striate, with a few fine punctures interspersed, except smooth, narrow distal area; with sparse yellowish brown pubescence except glabrous smooth area. Gulamentum shining, smooth, glabrous on wide basal area, micropunctate (interspersed with fine, shallow punctures distally), with sparse yellowish brown pubescence and a few long, erect yellowish setae close to mentum. Labrum convex, coplanar with anteclypeus on basal 2/3, inclined on distal third; nearly smooth basally, finely punctate near apex of basal 2/3, abundantly micropunctate on distal third; with sparse yellow pubescence on basal 2/3, denser, with long, erect yellow setae interspersed on distal third (longer and more abundant laterally), with fringe of yellow setae on distal margin. Distance between upper eye lobes 0.65 times length of scape (3.0 times width of one lobe); in frontal view, distance between lower eye lobes equal to length of scape. Antennae 1.85 times elytral length, reaching elytral apex at about middle of antennomere VIII. Scape abruptly widened near base on inner side; finely, moderately sparsely punctate; with yellowish brown pubescence partially obscuring integument, with long, erect yellowish setae interspersed throughout. Pedicel and antennomeres with long, erect yellowish setae ventrally, gradually shorter, sparser toward XI. Antennal formula (ratio) based on length of antennomere III: scape = 0.65; pedicel = 0.12; IV = 0.93; V = 0.70; VI = 0.60; VII = 0.58; VIII = 0.51; IX = 0.49; X = 0.45; XI = 0.45.

Thorax. Prothorax, maximum width 1.47 times wider than long (including lateral tubercles); lateral tubercles large, placed at middle, apex acute and directed backward. Pronotum with two slightly distinct gibbosities placed on each side of distal half; coarsely, moderately abundantly punctate except smooth centro-longitudinal wide band; with yellowish brown pubescence partially obscuring integument, with long, erect, yellow setae interspersed on basal half. Sides of prothorax coarsely, moderately sparsely punctate except smooth distal area (widened toward ventral side); with ashy yellow pubescence partially obscuring integument. Prosternum with row of coarse punctures close to procoxal cavities, finely, transversely striate laterally, smooth centrally; with ashy yellow pubescence not obscuring integument. Prosternal process centrally as wide as 1.4 times base of metafemora; with ashy yellow pubescence not obscuring integument; notably widened distally, with distal margin slightly projected centrally. Central area of mesoventrite with sparse ashy yellow pubescence, nearly glabrous toward prosternum, distinctly denser laterally. Metanepisternum moderately coarsely, sparsely punctate; with ashy yellow pubescence partially obscuring integument. Mesepimeron and metanepisternum nearly smooth, with pubescence as on metanepisternum. Mesoventral process depressed centrally. Metaventrite moderately finely, sparsely punctate laterally; with ashy yellow pubescence partially obscuring integument laterally, except glabrous, small, circular areas surrounding each puncture; central area nearly glabrous. Scutellum glabrous on centro-longitudinal area, with pale yellow, dense pubescence laterally. Elytra. Slightly, longitudinally carinate; coarsely, moderately abundant punctate on basal half, gradually finer, sparser toward apex (punctures nearly aligned in rows); with yellowish brown pubescence irregularly interspersed with ashy yellow pubescence, partially obscuring integument; apex almost truncate. Legs. Femora moderately finely, sparsely punctate; with ashy yellow pubescence partially obscuring integument except glabrous, small, circular areas surrounding each puncture.

Abdomen. Ventrites with ashy yellow pubescence partially obscuring integument except glabrous, small, circular areas surrounding each puncture; with long, erect, yellow setae laterally; distal margin of ventrite V slightly concave.

Dimensions (mm) male. Total length, 11.11; prothoracic length, 2.29; basal prothoracic width, 2.56; distal prothoracic width, 2.11; maximum prothoracic width (between apices of lateral tubercles), 3.37; humeral width, 3.55; elytral length, 7.51.

Material examined. MARTINIQUE: Le Diamant - M. Gardia, 1 male (ex larva), VI.2012, J. Touroult col. ( MZSP).
