15. Cyrea roberta Canepari and Gordon , new species

Description. Male holotype. Length 2.5 mm, width 2.0 mm; body rounded, convex. Dorsal surface with head weakly alutaceous, shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with 7 brown spots, large, triangular spot on basal border on each side of middle, 1 short, oval spot on basal margin anterior to scutellum, 1 obliquely oval spot on each side of middle of pronotum, and 1 small, round spot near lateral pronotal margin; elytron with brown sutural border from scutellum to apex, border widened in median 7/8, widest anterior to middle, with 3 brown spots present, lateral spot narrow, irregular, extended from humeral callus onto apical declivity, discal spot oval, feebly connected to brown sutural border, apical spot obliquely oval ( Fig. 77 ); ventral surface with head, prosternum, meso- and metaventrites dark brown; abdomen brown except median 2/3 of ventrites 1-4 darker brown. Head punctures small, separated by a diameter or less, each puncture slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures larger than on pronotum, separated by less than to about a diameter; metaventral punctures as large as on elytron medially, separated by about a diameter, 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 slightly curved, basal margin without trace of bordering line medially. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin slightly arcuate, smooth, sponda extended beyond angle. Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/6 of prosternum, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite with setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward at apex, ventrite with sparse, long pubescence and large, coarse punctures medially, punctures becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite deeply depressed in median 1/3, apex emarginate, lateral angle with dense tuft of setae; 6th ventrite deeply depressed medially, apex deeply emarginate with lateral angle abruptly rounded. Apical tergite finely, densely punctured, apex deeply, widely, sinuately emarginate medially, with lateral angle strongly projected, apically hooked. Genitalia with basal lobe slender, slightly shorter than paramere, asymmetrical, sides convergent from base to apex, apex abruptly rounded; paramere Pav, slightly widened from base to truncate apex, curved upward, upper margin with sclerotized projection, or “ear” slightly posterior to apex ( Fig. 78, 79 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm short, narrow, outer arm wider and longer than inner arm, with accessory piece, basal border weakly emarginate ( Fig. 80, 81 ).

Female. Similar to male except clypeus and apex of frons brown, pronotum with spots widened, somewhat fused, extended to anterior pronotal margin. Genitalia with spermathecal capsule short, slender, basal 1/4 widened, apical 3/4 narrow; bursal cap oval, with 3 sclerotized arms, apical strut long, slender ( Fig. 82 ).

Variation. Length 2.3 to 2.8 mm, width 1.8 to 2.1 mm. Pronotal spots vary in size and width, female pronotum sometimes with median spots entirely fused except for narrow yellow vitta at middle, elytron with elongate lateral spot variable in shape and length, sometimes nearly connected to discal spot, discal spot either narrowly connected to sutural border or entirely discrete.

Type material. Holotype male; Brazil, Chapada, Acc.No. 2966, Nov. ( CMNH) . Paratypes; 26; 20, same data as holotype except additional dates Feb, Apr, Oct., Dec. ( CMNH) ; 2, Brazil, Goiás, Corumbá, Fazenda Monjolinho , 14. VI.1942, F. Lane ( MZSP) ; 1, Brazil, Faz. Nova Orlandia, Jatai , Go - Brasil, I.964 - Martins, Morgane & Silva ( MZSP) ; 1, Itú - S.

Geographical distribution. Brazil; Paraguay.

Remarks. The dorsal color pattern is unique to this species. In addition, males are recognized by the setal tuft on the 5th basal abdominal ventrite, and apical tergite with lateral angle strongly projected, projection apically hooked.
