Hyperaspis corcovado , new species

( Figure 1-10 )

Description. Male holotype. Length 3.0 mm, width 2.4 mm. Body weakly elongate, convex. Dorsal surface with head alutaceous, feebly shiny, pronotum weakly alutaceous, slightly shiny, elytron smooth, shiny. Color reddish yellow except head yellow; pronotum with narrow, basal black macula apically emarginate; elytron with sutural border narrowly black, black area slightly widened medially, median, curved vitta present from base across humeral callus to sutural margin at apical 1/6 ( Fig. 1-4 ); base of head, prosternum, meso- and metaventrites black; abdomen dark brown medially, dark reddish brown laterally. Head punctures small, separated by a diameter or less; pronotal punctures larger than on head, separated by a diameter or less; elytral punctures slightly larger than on pronotum, separated by a diameter or less; punctures on metaventrite very large, separated by a diameter or less medially, becoming larger and nearly contiguous in lateral 1/4; punctures on basal abdominal ventrite large medially, separated by a diameter or less, becoming smaller, more scattered in lateral 1/3, punctures on sternites 2- 6 fine, sparse, separated by a diameter or less. Clypeal apex deeply emarginate, clypeus and frons joined at abrupt angle. Epipleuron wide, grooved medially, descending externally, femoral depressions deep. Antenna with 10 articles ( Fig. 10 ). Protibia narrow, slightly flanged. Prosternum with intercoxal carinae widely separated at apex, convergent toward base, joined at basal 2/3, connected to base by single stem. Postcoxal line on basal abdominal ventrite straight in basal 1/3, flattened along posterior margin of ventrite, rounded 5/6 distance to lateral margin ( Fig. 5 ). Fifth ventrite broadly, deeply emarginate apically; 6 th ventrite with broad, shallow apical emargination. Genitalia with basal lobe 2/3 length of paramere, narrow basally, strongly widened to truncate apex, one lateral margin sinuate with small, median projection; paramere elongate, slender, slightly tapered from base to apex; trabes long, apically curved laterally ( Fig. 8, 9 ); sipho long, curved in basal 3/4, basal capsule long, enlarged, inner arm long, narrow basally, widened apically, outer arm short, nearly absent, rectangular, abruptly bent, basal border widely emarginate ( Fig. 6, 7 ).

Female. Not known.

Type material. Holotype male: Brasil, Corcovado , Guanabara, VIII.1966, Alvarenga & Seabra, Coleção M. Alvarenga. ( DZUP).

Remarks. This species has the same basic dorsal color pattern as H. zonula Gordon and Canepari. However , the 10 articled antenna places it in the donzeli group, where it is immediately distinguished by the unique elytral color pattern. It resembles H. zonula to which it will go in the key to species, couplet 41 in Gordon and Canepari (2009) (if antenna is not examined), except that the ground color is darker, black areas more crisply defined, and male genitalia completely unlike those of H. zonula . In both species the curved elytral vitta is joined with the basal pronotal macula to form a circle, a pattern thus far unknown in any other South American Hyperaspis .

Etymology. The species name refers to the type locality, and is used as a noun in apposition.
