Cleothera nigripennis Brèthes, 1925b:4 .

Hyperaspis nigripennis: Korschefsky 1931:192 ; Blackwelder 1945:447.

Description. Male holotype. Length 2.7 mm, width 2.3 mm; body rounded, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron shiny, lacking alutaceous sculpture. Color yellow except pronotum with large, basomedian bluish black spot, lateral border of spot emarginate; elytron entirely bluish black ( Fig. 625 ); venter of head, prosternum, meso- and metaventrites black, epipleuron dark brown, abdomen reddish yellow. Head punctures small, nearly invisible, separated by less than to twice a diameter, each puncture as large as 2 eye facets; pronotal punctures larger than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than to twice a diameter; metaventral punctures larger than on elytron, separated by less than a diameter medially, becoming larger, nearly contiguous in lateral 1/4. Clypeus weakly emarginate apically, lateral angle abruptly rounded, surface with sparse, long pubescence. Eye canthus as long as about 6 eye facets, strongly angled forward, abruptly rounded apically, brown. Pronotum narrowed from base to apex, sides weakly rounded, basal and anterior angles abruptly rounded, basal margin without bordering line. Epipleuron wide, nearly flat, deeply emarginate for reception of femoral apices. Protibia not oblique, outer margin straight, sponda nearly absent. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/4, with single stem extended to prosternal margin. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite angled to ventrite apex, flat along border, then rounded forward to lateral 1/5 of ventrite; ventrites 1-4 with sparse, short pubescence, punctures on median 1/3 of basal ventrite large, separated by less than to twice a diameter, punctures on remaining ventrites small, dense, separated by less than a diameter; 5th ventrite with long, dense pubescence laterally on apical margin, apical margin weakly emarginate medially; 6th ventrite short, narrow, with dense pubescence on apical angle, medially grooved, apical angle evenly rounded, apex weakly emarginate, surface nearly impunctate. Genitalia with basal lobe long, slightly shorter than paramere, widened medially, tapered to rounded apex; paramere somewhat Psc, slender, abruptly curved ventrally in apical 1/6 ( Fig. 626, 627 ); sipho long, slender, curved in basal 1/2, basal capsule with inner arm long, slender, outer arm elongate, slender, without accessory piece, basal border broadly emarginate ( Fig. 628, 629 ).

Female. Unknown.

Variation. Unknown.

Type locality. Brazil, Rio de Janeiro.

Type depository. BMNH (holotype).

Geographical distribution. Known only from the type locality ( Brazil).

Specimens examined. 1. The holotype.

Remarks. Cyrea nigripennis is an unusual species primarily because of the entirely bluish black elytra reminiscent of Tiphysa species , but mostly unknown in Cyrea . It also has male genitalia of a form completely different from those of any presently known species.

Brèthes had a single type specimen, a holotype male labeled “Type (orange bordered disc)/type (handwritten in pencil)/1831 (handwritten)/Fry RioJan (handwritten)/Fry Coll. n 1905.100/ Cleothera nigripennis Brethes (handwritten).”
