39. Cyrea yvonne Canepari and Gordon , new species

Description. Male holotype. Length 2.8 mm, width 2.4 mm; body rounded, somewhat oval, convex. Dorsal surface with head, pronotum weakly alutaceous, shiny, elytron smooth, shiny. Color yellowish red except pronotum with barely perceptible M-shaped mark medially; elytron with barely perceptible yellow lateral border from base to sutural margin at apex ( Fig. 215 ); ventral surface yellowish red with antenna, mouthparts, legs yellow; abdomen yellowish red. Head punctures small, separated by less than to about a diameter, each puncture slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by less than to twice a diameter, elytral punctures larger than on pronotum, separated by less than to about 2 times a diameter; metaventral punctures larger than on elytron, separated by a diameter medially, larger and separated by less than a diameter in lateral 1/3. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin curved, basal margin without trace of bordering line medially. Epipleuron wide, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/4, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened medially along posterior ventrite margin, extended forward at apex, ventrite with sparse, long pubescence and small punctures sparse medially becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex emarginate with lateral angle abrupt. Apical tergite finely, densely punctured, apex weakly emarginate. Genitalia with basal lobe 2/3 as long as paramere, asymmetrical, sides convergent in basal 7/8, apical 1/8 curved to rounded apex; paramere Pem, strongly widened from base to weakly emarginate apex ( Fig. 216, 217 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm long, narrow medially, apex widened, truncate, outer arm wider and slightly longer than inner arm, with accessory piece, basal border shallowly, broadly emarginate ( Fig. 218, 219 ).

Female. Similar to male externally. Genitalia with spermathecal capsule short, slender, basal 1/4 slightly wider than apical 3/4; bursal cap oval with 2 slender, sclerotized arms, apical strut short, slender, spatulate in apical 1/2 ( Fig. 220 ).

Variation. Length 2.8 to 3.0 mm.

Geographical distribution. Brazil.

Type material. Holotype male; ( Brazil) V. Monte Verde, Minas Gerais, F. Halik, 17.IX.1962, 20198, Brasil, Halik 1966 Collection. ( USNM) . Paratypes; 2, same data as holotype ( USNM) .

Remarks. The dorsal surface appears to be immaculate, but the elytron has a barely perceptible yellow lateral border. For practical purposes, C. yvonne is considered immaculate, and will key out accordingly.
