Description. Male. Length 2.6 mm, width 2.1 mm; body rounded, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except pronotum with narrow, black basomedian macula extended about 2/3 distance to anterior pronotal margin, macula with apical border curved, weakly indented with yellow medially; sutural margin of elytron with black border in most of median 1/2, 3 black maculae fused into a single irregular median spot on each elytron ( Fig. 53 ); ventral surface with head, prosternum meso- and metaventrites dark brown; abdomen 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 1 to 2 times a diameter; metaventral punctures larger than on elytron, separated by 1-3 times a diameter medially, becoming larger and separated by less than a diameter in lateral 1/5. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 4 eye facets long, slightly angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin weakly rounded, basal margin without trace of bordering line medially. Epipleuron wide, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin straight, smooth, sponda slightly extended beyond oblique angle. Carinae on prosternal process narrowly separated at apex, convergent toward base, joined slightly anterior to middle of prosternum, single carina extended to prosternal base. Metaventrite without setal tuft. Basal abdominal ventrite with sparse setal tuft. Abdomen with postcoxal line on basal abdominal ventrite slightly flattened along posterior ventrite margin, extended forward at apex, ventrite with small, dense punctures; ventrites 2-6 pubescent throughout, punctures fine, dense; 4th ventrite depressed in median 1/3, apex deeply emarginate; 5th ventrite depressed medially, apical margin broadly, feebly emarginate; 6th ventrite short, narrow, depressed medially, apical border emarginate, angle on each side of emargination abrupt. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe about 3/4 as long as paramere, asymmetrical, sides parallel in basal 5/6, apex asymmetrically triangular; paramere Pav, widened from base to obliquely rounded apex, upper margin with sclerotized projection, or “ear” slightly posterior to apex ( Fig. 54, 55 ); sipho strongly curved in basal 1/2, with trace of visible alae at apical 1/10, basal capsule with inner arm short, wide, apex widened, dorsally rounded, outer arm about as wide as and longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 56, 57 ).

Female. Similar to male except head with clypeus and apex of frons brown, pronotum with basomedian macula extended to anterior pronotal margin. Genitalia with spermathecal capsule short, wide, weakly curved, basal 1/2 wide, apical 1/2 narrow; bursal cap oval, without visible arms, apical strut short, spatulate in apical 1/2 ( Fig. 58 ).

Variation. Length 2.3 to 2.7 mm, width 1.7 to 2.2 mm. Elytron sometimes with black sutural border long, wide, widened at apex on apical declivity, spot in anterior 1/2 extended posteriorly onto apical declivity ( C. trivittata ) or with sutural border and spot on anterior 1/2 very long, wide ( C. munda ).

Type locality. Of emiliae , Brazil; of trivittata , Brazil, Rio Grande do Sul; of mundula , Argentina, Gobernación Misiones.

Type depository. Of emiliae, UMZC (holotype); of trivittata, ZMHB (lectotype here designated); of mundula, MBR (lectotype here designated).

Geographical distribution. Argentina, Brazil, Paraguay.

Specimens examined. 53. Argentina. Gobernación, Misiones. Brazil. Curitiba; Minas Gerais, V. Monte Verde; PR, San Jose dos Pinheiros, Sao Paulo; SC, Nova Teutonia. Paraguay. Caaguazú, Repatriación; Hohenau. ( BMNH) ( CNC) ( DZUP) ( GGC) ( MNHNP) ( MNRJ) ( UMZC) ( USNM) ( ZMHB).

Remarks. Cyrea emiliae has a somewhat variable elytral color pattern paired with highly distinctive male genitalia. Although variable, the dorsal color pattern will usually serve for identification purposes. Three names have been proposed for this species, but examination of male genitalia of each of the types indicates that only one species is involved.

The lectotype of C. trivittata in the ZMHB is labeled “ Rio grande do sul (green paper, handwritten)/ Cleothera trivittata m. (handwritten)/ex. coll. J. Weise/ SYNTYPUS Hyperaspis trivittata Weise, 1902 labeled by MNHUB 2004 (red paper).” The lectotype of C. mundula in the MBR is labeled “ Misiones / female sign/ TYPUS/ Cleothera mundula Weise. ”
