description: Hyperaspis pectoralis Crotch   
(Figure 94-103)  
 Hyperaspis pectoralis Crotch, 1874: 225; Korschefsky, 1931: 193; Blackwelder, 1945: 448.   
 Description. Male. Length 3.0 mm, width 2.6 mm. Body rounded, convex. Dorsal surface with head strongly alutaceous, pronotum slightly alutaceous, weakly shiny, elytron smooth, shiny. Color yellow except pronotum with small, faintly defined, brown basal macula on each side of middle, pronotum and elytron appearing “dirty” yellow because dorsal punctures are brown; elytron with faint darker “cloud” occupying discal area onto apical declivity (Fig. 94-97); prosternum, meso- and metaventrites black; abdomen brownish yellow. Head punctures small, separated by 2-4 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 twice a diameter; punctures on metaventrite small, widely scattered medially, becoming very large, separated by less than a diameter in lateral 1/2; punctures on basal abdominal ventrite small, separated by 2 to 4 times a diameter, punctures on ventrites 2-6 fine, sparse, separated by less than to 4 times a diameter. Clypeal apex deeply emarginate, clypeus and frons joined at abrupt angle. Epipleuron wide, grooved medially, slightly descending externally, femoral depressions deep. Antenna with 11 articles. Protibia narrow, not flanged. Prosternum with intercoxal carinae narrowly separated at apex, weakly convergent toward base, joined before base and connected to base by single stem. Postcoxal line on basal abdominal ventrite broadly arcuate, reaching posterior ventrite margin, rounded 7/8 distance to lateral margin (Fig. 98). Fifth ventrite broadly, weakly emarginate apically; 6 th ventrite with shallow, narrow, apical emargination nearly truncate. Genitalia with basal lobe short, 1/2 length of paramere, apex narrowed, triangular, with strong lateral projection; paramere short, basally wide, apex rounded (Fig. 101-103); sipho long, robust, with apical membranous area, basal capsule with inner arm long, straight, apically knobbed, outer arm short, wide, basal border deeply emarginate (Fig. 99, 100).   
 Female. Not known.   
 Type locality. Brazil.   
 Type depository. UMZC (holotype).   
 Specimens examined. 2. Brazil. The holotype; Sao Paulo, Cantareira. (MZSP).   
 Remarks. An unusually colored species, H. pectoralis will not go beyond couplet 2 in the species key (Gordon and Canepari 2008) because it has no dorsal color pattern. It is described as being dorsally yellow, but this is a “dirty” yellow because the bottom of the punctures are distinctly or faintly brown. Male genitalia place it in the onerata group, but the round, convex body form differs from other species in that group.   
 The type specimen is a holotype male in the Crotch collection (UMZC). This species was omitted from the Hyperaspis revision (Gordon and Canepari 2008) because it was mistakenly identified as a member of the Brachiacanthini genus Cyra Mulsant.
