67. Cyrea dolores Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 1.8 mm; body elongate, oval, convex. Dorsal surface with head feebly alutaceous, shiny, pronotum and elytron smooth, shiny. Color reddish yellow except pronotum mostly black with anterior 1/6 and lateral 1/8 yellow, median portion of black area with 3 small, yellow spots, median spot elongate, triangular on each end, lateral spot round; elytron reddish yellow with basal, sutural, and apical margins narrowly black, basal border narrowly projected posteriorly onto humeral callus, sutural border slightly widened anterior to middle, a narrow, yellow border present inside black border, yellow border widest laterad of scutellum ( Fig. 369 ); ventral surface with head, prosternum, meso- and metaventrites dark brown, proleg with dark brown femur, meso- and metalegs entirely dark brown; abdomen dark brown. Head punctures small, separated by a diameter or less, each puncture as large as an eye facet; pronotal punctures slightly larger than head punctures, separated by 1 to 3 times a diameter; elytral punctures as large as pronotal punctures in inner 1/3, outer 1/3 with punctures much larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures fine, sparse medially, as large as outer pronotal punctures and separated by a diameter or less 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 feebly rounded, basal margin without trace of bordering line medially. Epipleuron narrow, not grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin straight, smooth, sponda slightly extended beyond angle. Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/10, 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. Apical tergite medially grooved, finely, densely punctured, apex emarginate. Genitalia with basal lobe as long as paramere, slightly asymmetrical, widened from base to abruptly rounded apex; paramere Psc, wide, widened from base to truncate apex, lower anterior angle projected ( Fig. 370, 371 ); sipho strongly curved in basal 2/3, with visible alae at apical 1/12, basal capsule heavily sclerotized, inner arm long, narrow, apex rounded, with short basal projection, outer arm straight, slightly wider and longer than inner arm, with accessory piece, basal border deeply, broadly emarginate ( Fig. 372 ).

Female. Similar to male except head black, black area of pronotum extended to anterior pronotal margin. Genitalia with spermathecal capsule long, slender medially, basal 1/4 widened, apex of cornu bulbous; bursal cap oval, with 3 sclerotized arms, apical strut short, slender ( Fig. 373 ).

Variation. Length 2.6 to 3.3 mm, width 1.8 to 2.6 mm. Elytron with black border variable in width from very narrow to as described for the holotype to wide, projection of basal border onto humeral callus present or absent, yellow border outside of black border variable in width and distinctness.

Type material. Holotype male; ( Brazil) Vila Monte Verde , Minas Gerais, I. III 1971, F. Halik, 11378 ( MZSP) . Paratypes; 3, same data as holotype except additional dates 18.XI.1966, 18.II 1969, 2.II 1970 ( MZSP) .

Geographical distribution. Brazil.

Remarks. The dorsal color pattern is highly diagnostic for this species, especially the unique pronotal pattern of 3 small, yellow spots on a black background. This is a handsome species with its contrasting reddish yellow, black, and yellow dorsal pattern.
