TYPE LOCALITY. — French Guiana, montagne des Chevaux, 4°43’N, 52°25’W.

ETYMOLOGY. — This species is dedicated to Mr. Stéphane Brûlé (Société entomologique Antilles-Guyane) who spends a lot of time collecting and sorting out many very interesting Brentidae   from French Guiana, and who kindly sends them to me for study.

DISTRIBUTION. — French Guiana. See map ( Fig. 16D View FIG ).

DIAGNOSIS (MALES). — Golden green species; setae on venter of rostrum not reaching prorostrum; apical tooth of elytra not rimmed, section circular; first metatarsal segment not carinate on upper side; sternites III-IV of abdomen with large, shallow and glabrous longitudinal depression.

DESCRIPTION

Males

Measurements. Length of head (rostrum included): 3.7- 5.4 mm; length of body (from front margin of pronotum to apex of elytra): 8.3-12.0 mm; width across humeral calli: 1.5-2.3 mm. Metallic golden green except rostrum, antennae, first elytral interstria and legs reddish. Habitus: Fig. 4A View FIG .

Head. Prorostrum much shorter than metarostrum and mesorostrum together ( Fig.9F View FIG ). Mesorostrum elevated,longitudinally grooved. Metarostrum not grooved, with weak median carina, weakly carinate on sides. Eyes large, prominent, slightly longer than temples. Head smooth, hardly tapering backwards, with weak inter-ocular fovea sometimes missing; collar constriction well marked. Sides and venter of head with few pores. Sides of metarostrum almost glabrous and without pores; venter with two longitudinal rows of small sensorial pores sometimes very hairy, often reaching base of prorostrum, without median carina, grooves or smooth area. Venter of prorostrum smooth.

Antennae. Antennae ( Fig. 9G View FIG ) with segments 2-8 longer than broad, subconical, with long setae; 9 less than 1.5 ×longer than 8.

Thorax. Pronotum 2 × longer than broad, not punctate. Elytra not depressed at base of interstria 5. Apex of elytra extended by quite small tooth formed mainly by interstriae 9 and 11, not much dorso-ventrally flattened, without outer rim ( Fig. 9H View FIG ). Prosternum with few large punctures in front of bulging procoxae, area in front of procoxae depressed. Mesothorax with few punctures on sides; mesanepisternum with deep punctures; mesepimeron with deep confluent punctures. Metanepisternum with row of punctures. Legs with mesocoxae, metacoxae and trochanters bearing setae; femora strongly pedunculate, not depressed laterally, glabrous except metafemora with few hairs below at base. Tibiae quite long, hairy on inner side; apex of metatibia with acute calcar on inner side. First tarsal segment longer than broad, shorter than 2-3 together; segment 2 slightly longer than broad ( Fig. 9I View FIG ).

Abdomen. Abdomen ( Fig. 9J View FIG ) with sternites III-IV glabrous, smooth, with quite large longitudinal median depression. Tegmen with parameroid lobes rounded at apex, with few setae ( Fig. 12A View FIG ). Internal sac with short proximal hook-like sclerite pointed at the apex, with hole at base allowing insertion of ejaculatory duct; few tiny proximal sclerifications on wall of the internal sac and small spicules rearward ( Fig. 12A View FIG ).

Females

Measurements. Length of head (rostrum included): 3.5- 4.3 mm; length of body (from front margin of pronotum to apex of elytra): 8.3-10.9 mm; width across humeral calli: 1.5- 2.0 mm. Pattern of coloration as in males. Habitus: Fig. 4B View FIG .

Head. Mesorostrum elevated, slightly grooved longitudinally. Metarostrum without median carina, not carinate on sides, without paramedian grooves. Eyes longer than temples, quite bulging. Head foveate between eyes, tapering backwards, collar constriction weak.Sides and venter of head with few large sensorial pores. Sides and venter of metarostrum with large sensorial pores, arranged in two rows below, reaching base of mesorostrum; no median elevated area separating both rows of pores.

Antennae. Antennae with segments 2-8 slightly hardly longer than broad, subconical, with few long setae; 9 less than 1.5 × longer than 8.

Thorax. Pronotum almost 2 × longer than broad, not punctate. Elytra not depressed at base of interstria 5; interstria 3 quite elevated at base. Apex of each elytron extended as one tooth formed mainly by interstriae 9 and 11. Prosternum with few large punctures in front of bulging procoxae, area in front of procoxae depressed. Mesothorax with few punctures on sides; mesanepisternum punctate; mesepimeron with deep confluent punctures. Metanepisternum with row of shallow punctures. Legs with mesocoxae, metacoxae and trochanters setose; femora not depressed laterally, glabrous except metafemora with few hairs below at base. Tibiae quite long, hairy on inner side. First tarsal segment shorter than 2-3 together; segment 2 as long as broad.

Abdomen. Abdomen with sternites III-IV convex, glabrous, smooth except punctures in front part of sternite III along metacoxae, without groove. Tergite VIII: Fig. 15B View FIG . Epipleurites VIII: Fig. 15C View FIG . Coxites, genital tract and spermatheca: Fig. 15D View FIG ; vagina not sclerified.
