Hyperaspis unimaculosa , new species

( Figure 59-69 )

Description. Male holotype. Length 2.6 mm, width 2.3 mm. Body rounded, convex. Dorsal surface with head strongly alutaceous, dull, pronotum slightly alutaceous, shiny, elytron smooth, shiny. Color black except head yellow; pronotum black with anterior 1/6 and lateral 1/4 yellow, lateral yellow area indenting median black spot medially; elytron black with lateral and apical margins narrowly yellow, yellow apical border widened ( Fig. 59-63 ); propleuron, epipleuron, legs yellow; abdomen reddish yellow except median 1/ 3 of basal ventrite dark brown. Head punctures small, nearly invisible, separated by 4-6 times a diameter; pronotal punctures larger than on head, separated by less than to twice a diameter; elytral punctures larger than on pronotum, separated by less than to three times a diameter; punctures on metaventrite larger than on elytron, separated by about a diameter, becoming coarser laterally, separated by less than a diameter; punctures on basal abdominal ventrite small, separated by 2 to 4 times a diameter, punctures on ventrites 2-6 fine, sparse, nearly invisible, separated by less than to 4 times a diameter. Clypeal apex deeply emarginate, clypeus and frons joined at abrupt angle. Epipleuron wide, slightly grooved medially, slightly descending externally, femoral depressions deep. Antenna with 11 articles. Protibia narrow, not flanged. Prosternum with intercoxal carinae widely separated at apex, strongly convergent toward base, joined just before base, connected to base by single stem. Postcoxal line on basal abdominal ventrite arcuate, slightly flattened in median 1/3 along posterior margin of ventrite, rounded 7/8 distance to lateral margin ( Fig. 64 ). Fifth ventrite broadly, weakly emarginate apically; 6 th ventrite obliquely rounded. Genitalia with basal lobe short, 1/2 length of paramere, strongly sinuate, apex oblique rounded, with strong lateral projection; paramere short, wide, apex rounded ( Fig. 68, 69 ); sipho long, slender, with apical membranous area, basal capsule with inner arm long, straight, apically knobbed, outer arm short, wide, basal border weakly emarginate ( Fig. 66, 67 ).

Female. Similar to male except anterior pronotal margin black. Genitalia with basal unit lacking beak, sperm duct short ( Fig. 65 ).

Variation. Length 2.6 to 3.0 mm, width 2.3 to 2.6 mm. The Corcovado paratype has the outer yellow ring present only posterior to apical declivity.

Type material. Holotype male: Barueri , Sao Paulo - Brasil, XII.1965, K. Lendo col. ( MZSP) . Paratypes, 4; 3, same data as holotype ; 1, Brasil Rio do Janeiro , D. F. (Distrito Federal), Corcovado, X-1957, Seabra & Alvarenga. ( MZSP) ( USNM) .

Remarks. Hyperaspis unimaculosa somewhat resembles H. uninotata Gordon and Canepari to which it goes in the key to species, couplet 45 in Gordon and Canepari (2008), but H. unimaculosa has the outer elytral ring of yellow only on the lateral and/or apical borders, H. uninotata has the anterior border also yellow; male genitalia are quite different from those of H. uninotata ; and female genitalia have a beaked basal unit. Male genitalia of H. unimaculosa are most similar to those of species in the notata group

Etymology. The species name is constructed from the Latin uno meaning one, and macula, meaning spot. It also references the similar appearing H. uninotata .
