Caperonotus tucurui Napp & Monné New species

Figs 1, 4

Description. Male. Head and ventral surface of the body light metallic green, slightly golden. Antennae and legs black, the scape and femora with strong metallic green reflections. Elytra entirely black, strongly opaque. Scutellum black.

Head glabrous. Frons and vertex coarsely, deeply, densely punctate to corrugate. Genae with smaller punctures, irregularly dense. Clypeus subopaque, punctate, with a subtriangular, smooth, raised area at base.

Mandibles coarsely punctorugose, with long, very conspicuous brown setae. Apical segments of maxillary and labial palps conical, truncate at apex, shorter than the two preceding combined.

Antennae exceeding elytral apex by almost five segments; shining, without pubescence. Scape cylindrical about one third shorter than segment 3; with coarse, irregularly dense punctures, sparser apically; pilosity sparse. Segments 3 to 5 irregularly, asperate punctate with dense, long setae beneath; segments from 7 almost impunctate and glabrous. Segment 3 about one third longer than the following 4 to 10 which are subequal and decreasing in length; 11 as long as 3.

Prothorax ( Fig. 4 ) almost glabrous. Pronotum shining, plicate with conspicuous intermingled punctures except at the central, smooth area. Sides of prothorax subopaque, densely punctorugose. Prosternum opaque, dense and confluently punctate with the interstices forming very irregular striae; intercoxal process with a rounded apical impression. Mesosternum with coarse punctures denser on disk; intercoxal process punctorugose, raised in front and between mesocoxae and strongly impressed on each side. Metasternum and uros- ternites almost smooth and subglabrous. Fifth urosternite widely rounded-truncate at apex.

Scutellum small, transverse, almost smooth and glabrous. Elytra strongly opaque, very densely punctorugose throughout, the punctures contiguous and gradually smaller apically; pilosity inconspicuous. Apices somewhat oblique, narrowly emarginate near suture; sutural angle dentate, outer angle with obtusely projected.

Femora subclavate, almost impunctate, subglabrous; mesofemora more conspicuously punctate; metafemora not reaching elytral apices.

Measurements (mm) male. Total length 11.2; prothorax length 2.3; prothorax maximum width 2.8; elytral length 7.7; humeral width 3.3.

Types. Holotype male from BRAZIL, Pará: Tucuruí , I.1979, (M. Alvarenga col.), deposited in MNRJ.

Remarks. Caperonotus tucurui Napp & Monné sp. nov. is similar to C. cardinalis by the pronotum plicate and punctate, prosternum and sides of prothorax densely punctorugose, elytra with contiguous punctures on the entire surface, and apical segments of palps conical, shorter than the two preceding combined. C. tucurui differentiates mainly by the whole black elytra which are densely punctorugose, the punctures gradually smaller apically; by the intercoxal process of the mesosternum raised in front of and between the mesocoxae and strongly impressed on each side, and by the more elongate prothorax and elytra ( Fig. 1 ). In addition, the metallic green color is lighter, somewhat golden in the head and prothorax. In C. cardinalis ( Fig. 2 ), the elytra are bicolored – orangish with the apical fourth metallic bluish-green to violaceous - and uniformly punctate on the entire surface, the body integument dark metallic green, the mesosternal process plane or somewhat depressed between the mesocoxae and the prothorax and elytra shorter and wider than those of the new species.

Etimology. The specific epithet refers to the type locality.
