Description. Male lectotype. Length 3.5 mm, width 2.8 mm; body broadly rounded, somewhat flattened. Color yellow except pronotum with median dark brown area extended from base to anterior 5/6; elytron with suture narrowly dark brown from base to apical declivity ( Fig. 344 ); ventral surface with head, prosternum, meso-, and metaventrite black, abdomen dark brown medially, bordered with yellow. Head punctures large, separated by a diameter or less, each puncture as large as 4 eye facets; pronotal punctures smaller than on head, separated by 1 to 3 times a diameter; elytral punctures larger than on pronotum, separated by 2 to 3 times a diameter; metaventral punctures much larger than on pronotum, nearly absent medially, becoming larger and widely spaced toward lateral margin. Clypeus strongly emarginate apically, lateral angle abruptly rounded, surface with sparse, long pubescence. Eye canthus as long as about 6 eye facets, angled forward, abruptly rounded apically, yellow. Pronotum narrowed from base to apex, sides rounded, basal and anterior angles abruptly rounded, basal margin without bordering line. Epipleuron wide, strongly descending externally, weakly grooved, deeply emarginate for reception of femoral apices. Protibia weakly oblique, flange 1/2 width of tibia, outer margin smooth; sponda shallow. Carinae on prosternal process weak, nearly invisible, no apparent extension to base. Metaventrite without median setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded, extended to apical margin of ventrite at middle, then broadly forward to lateral 1/5 of ventrite; ventrites 1-4 with sparse, long pubescence, punctures sparse medially becoming dense laterally; 5th ventrite weakly depressed medially in apical 1/2, apical margin weakly emarginate medially, surface densely punctate; 6th ventrite short, narrow, not depressed in apical 1/2, apical margin nearly truncate, densely pubescent, surface smooth, glabrous. Apical tergite finely, densely punctured. Genitalia with basal lobe longer than paramere, asymmetrical, narrowed to rounded apex; paramere Pvl, wide ( Fig. 345, 346 ); sipho slender, strongly curved, without obvious lateral alae, basal capsule large, inner arm short, wide, apically truncate, outer arm longer than inner arm, with small accessory piece, basal border deeply emarginate ( Fig. 347, 348 ).

Variation. Unknown.

Type locality. Brazil.

Type depository. BMNH (lectotype here designated).

Geographical distribution. Bolivia, Brazil.

Specimens examined. 1. The lectotype.

Remarks. This species has a comparatively distinctive color pattern vaguely resembling that of C. melanura , it also has an unusual, dorso-ventrally flattened habitus, an epipleuron with a strongly descending external margin, and an apparent lack of prosternal carinae. All of which set it apart from other known species of Cyrea .

The lectotype is labeled “Type (orange bordered disc)314/80.23 (handwritten)/ Cleothera spinalis, Muls, T Brazil (blue paper, handwritten)/Named by Mulsant.” Mulsant (1853) had specimens from both Bolivia and Brazil.
