DISTRIBUTION. — Brazil (Amazonian Basin). See map ( Fig. 16D ). ETYMOLOGY. — The adjectival specific epithet used to name this new species refers to its distribution in the Amazonian Basin. DIAGNOSIS (MALES). — Elytra and pronotum metallic green; antennomeres 3-8 much longer than broad; mesorostrum and metarostrum together more than 1.5 × longer than prorostrum; 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 narrow and deep longitudinal depression. DESCRIPTION Males Measurements. Length of head (rostrum included): 4.9- 7.7 mm ; length of body (from front margin of pronotum to apex of elytra): 10.0- 14.5 mm ; width across humeral calli: 1.6-2.3 mm . Elytra metallic green; pronotum metallic but sometimes much less shiny than elytra; head, rostrum, antennae, first elytral interstriae and legs reddish. Habitus: Fig. 4G . Head. Prorostrum much shorter than metarostrum and mesorostrum together. Mesorostrum elevated, longitudinally grooved. Metarostrum not grooved, with weak median carina sometimes missing, not or very weakly carinate on sides. Eyes large, prominent, shorter than temples. Head smooth, 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 setae, without median carina or grooves, sensorial pores small, not reaching base of prorostrum. Venter of prorostrum smooth.

Scale bar: 5 mm. Antennae. Antennae ( Fig. 9A ) with segments 2-8 much longer than broad, subconical, with long setae; 9 less than 1.5 × longer than 8. Thorax. Pronotum more than 2 × longer than broad, not punctate. Elytra hardly depressed at base of interstria 5. Apex of elytra extended by quite massive tooth formed mainly by interstriae 9 and 11, not flattened dorso-ventrally, without outer rim ( Fig. 9C ). Prosternum with few large punctures in front of bulging procoxae, area in front of procoxae depressed. Mesothorax with few punctures on sides;mesanepisternum with large punctures;mesepimeron almost smooth.Metanepisternum with row of punctures hardly distinct. Legs with mesocoxae, metacoxae and trochanters setose; femora strongly pedunculate, not depressed laterally, glabrous except metafemora with few short thick hairs below at base. Tibiae quite long, hairy on inner side; calcar on inner side at apex of metatibia very short ( Fig. 9B ). First tarsal segment shorter than 2-3 together; segment 2 hardly longer than broad ( Fig. 9D ). Abdomen. Abdomen ( Fig. 9E ) with sternites III-IV glabrous, smooth, with deep but quite narrow longitudinal median depression. Tegmen with parameroid lobes elongate, rounded at apex, with few setae ( Fig. 12B ). Penis elongate; internal sac with short proximal hook-like sclerite pointed at apex, elongate, with hole at base allowing insertion of ejaculatory duct; few tiny sclerifications proximally on wall of internal sac and small spicules rearward ( Fig. 12B ). Females I am not able to attribute with certainty any of the female examined to this taxon.
