16. Cyrea melanie Canepari and Gordon , new species

Description. Male holotype. Length 2.7 mm, width 2.3 mm; body rounded, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except pronotum with brown basomedian macula extended slightly more than 1/2 distance to apical pronotal margin, apex of macula deeply, widely emarginate with yellow medially; elytron with 4 brown spots, humeral spot broadly oval, extended from humeral callus posteriorly to middle of elytron, discal spot narrowly elongate on sutural margin, posterolateral spot on apical declivity small, transversely oval, posteromedian spot on apical declivity narrowly elongate on sutural margin ( Fig. 83 ); ventral surface with head, prosternum, meso- and metaventrites dark brown; abdomen brownish yellow. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures larger than head punctures, separated by a diameter or less, elytral punctures larger than on pronotum, separated by less than to twice a diameter; metaventral punctures larger than on elytron medially, separated by about a diameter, larger and separated by less than a diameter in lateral 1/2. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin straight, basal margin without trace of bordering line medially. Epipleuron wide, grooved, slightly descending externally, deeply foveolate?? for reception of femoral apices. Protibia with wide flange, outer margin with a strongly arcuate, bisinuate, smooth flange, sponda extended beyond flange ( Fig. 84 ). Carinae on prosternal process narrowly separated apically, convergent toward prosternal base, incomplete, not joined apically, extended less than 1/2 distance to prosternal base. Metaventrite without setal tuft. Basal abdominal ventrite with setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward at apex, ventrite with sparse, long pubescence and large, coarse punctures medially, punctures becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite deeply depressed in median 1/3, apex emarginate, lateral angle with dense tuft of setae; 6th ventrite deeply depressed medially, apex deeply emarginate with lateral angle abruptly rounded. Apical tergite finely, densely punctured, apex deeply emarginate medially, with lateral angle strongly projected, apically hooked. Genitalia with basal lobe slender, 3/4 as long as paramere, asymmetrical, sides convergent from base to apex, apex rounded; paramere Pav, slightly widened from base to truncate apex, feebly sinuate, curved upward, upper margin with sclerotized projection, or “ear” slightly posterior to apex ( Fig. 85, 86 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm long, wide, outer arm slightly wider and longer than inner arm, with accessory piece, basal border weakly emarginate ( Fig. 87, 88 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; ( Brazil) Corumba , Matt. Grosso, Nunenmacher Collection. ( CAS).

Geographical distribution. Brazil.

Remarks. This species has male abdominal and genitalic structures very similar to those of C. roberta , but the dorsal color pattern differs widely between the two species. The protibia of C. melanie is unusual in having a widely expanded, bisinuate outer flange. That structure is rarely found elsewhere in the genus.
