Diagnosis. Nearly all surfaces coarse, with brown orangish pilosity and dark brown marbling; whitish flattened elytral disc with inversed darker “V” in middle.

Description. Male ( Figures 1 A–C) Head: Integument dark brown with coarse surface strongly punctate,

subquadrate, clypeus trapezoidal, glabrous and translucent, labium with borders rounded laterally and barely emarginate at center. Upper interocular space wide as 1.3 upper ocular lobe width.

Antennae short. Antennal formula, length compared with scape: I=1.0; II=0.4; III=2.6; IV=1.5; V=0.6; VI=0.5; VII=0.5; VIII=0.5; IX=0.5; X=0.4; XI=0.4.

Thorax transverse, 1.2 times wider than long, with two lateral smooth gibbosities and base constricted. Integument coarse, deeply and irregularly punctate, dark brown with irregular brushes of lying orange pilosity; anterior border with two small tubercles close to middle, with a small orange brush of pilosity; two tubercles laterally on disc border and one in middle before basal constriction. A few erect setae at base laterally. Prosternum with deep punctures separate with orangish pilosity covered integument. Prosternal process wide (slightly wider at middle length than a procoxa), triangular and deeply punctate, its lateral sides straight and notched apex. Scutellum subquadrate, covered with orange pilosity laterally and greyish pilosity in middle. Mesosternal process wide, slightly wider than a mesocoxa, with emarginate apex.

Elytra 2.2 times longer than wide, with subparallel borders, base with one small tubercle, apical region with five tubercles, the three closer to suture more distinct and with dense erect squamous pilosity, the two more lateral and apical tubercles smoother; apex widely rounded. Surface irregular, coarse and deeply punctate at humeri, on lateral slopes and apical quarter, with irregular brushes of brown orangish pilosity; from scutellum to apical quarter, disc flat, regular, with sparse deep punctures, almost completely covered with whitish pilosity; at basal third, density of pilosity increased, forming an upside down “V”, followed apically by a darker parallel V-shaped area due to pilosity shortening, making integument visible. Stronger orange brushes bordering the central flat area, near humeri basally and suture apically; two thinner orange brushes at apical slope. Metasternum deeply punctate, the median suture only visible on apical half.

Legs covered with brown orangish and dark brown pilosity forming rings on tibiae: two basal and one partial ring at middle of protibiae, one middle ring on mesotibiae and metatibiae. Modified profemora, sinuous and strongly widening, anterior border with a deep sulcus; the latter ventrally limited by a serrated ridge and a row of long erect black setae, underside with pilosity similar to dorsal side (no glabrous area); protibiae sinuous, with a dense longitudinal brush of erect short black setae.

Female. Unknown.

Dimensions (in mm). Total length: 5.5; thoracic length: 1.2; thoracic width: 1.4; elytral length: 3.8; elytral width at humeri: 1.7. Size range (mm): total length: 5.50–7.25.

Etymology. I take pleasure in naming this species in honour of Olivier Pascal (PNI) who organized the expedition to Mitaraka Mounts in French Guiana, for his friendship and sense of humor.
