Hyperaspis aliciae Crotch, 1874: 215 ; Korschefsky 1931: 184; Blackwelder 1945: 446; Gordon 1987: 27.

Description. Male holotype. Length 3.6 mm, width 3.3 mm; body rounded, convex. Color yellow except clypeus narrowly brownish black; pronotum with small, irregular brown macula on each side of middle at base, small round, brown spot laterad of basal macula in basal 1/4, and faint brownish yellow maculae medially; elytron with 5 black maculae arranged as in Fig. 492 , sutural border narrowly black except black area widened medially and before apex; ventral surface with head, prosternum, meso–, metaventrites dark reddish yellow; flanged outer margin of protibia and apical 1/2 of profemur black; abdomen dark yellowish brown. Head punctures small, separated by less than diameter, as large as 1–2 times an eye facet; pronotal punctures same size as head punctures, elytral punctures much larger than on pronotum, separated by 1–2 times diameter; metaventral punctures 3 or 4 times as large as on pronotum separated by diameter or more medially, becoming larger and contiguous laterally. Clypeus apically emarginate, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, straight, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange angled and widened from base to sponda, outer margin smooth, sponda represented by diagonal ridge across flange ( Fig. 493 ). Carinae on prosternal process wide at apex, narrowed basally, slightly pinched medially, acutely joined at base with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/8 of ventrite 4; postcoxal line on basal abdominal ventrite rounded, extended to apical margin of ventrite at middle, then broadly forward. Ventrites 2–4 sparsely pubescent throughout, punctures small, sparse medially, becoming dense laterally; 5th ventrite depressed medially, with small, distinct tubercle on each side of middle, dense patch of long pubescence on each side of median depression, apical margin deeply emarginate, surface densely punctate; 6th ventrite short, narrow, depressed in apical 1/2, apical margin deeply emarginate, densely pubescent on each side of median depression, without median tubercle, surface densely punctured. Apical tergite coarsely, densely punctured, pubescent, apex slightly rounded. Genitalia with basal lobe slightly shorter than paramere, slender, narrowed from base to rounded apex; paramere Unm type, wide, apex feebly widened ( Fig. 494, 495 ); sipho robust, strongly curved, basal capsule large, inner arm long, narrow, outer arm wide, slightly shorter than inner arm, with large accessory piece, basal border deeply emarginate ( Fig. 496, 497 ).

Female. Unknown.

Variation. Unknown.

Type locality. Brazil, “N. Frib” (Nova Friburgo) (southern Brazil).

Type depository. UMZC (holotype).

Geographical distribution. Known only from the Brazilian type locality.

Specimens examined. 1. Brazil. The holotype, N. Frib. (Nova Friburgo). ( UMZC).

Remarks. The dorsal color pattern is diagnostic, although similar to several other species of Brachiacanthini . In addition, the black, obliquely flanged protibia is unique to this species, resembling only the protibia of the much different S. humerata .
