52. Cyrea minnie Canepari and Gordon , new species

Description. Male holotype. Length 2.4 mm, width 1.8 mm; body elongate oval, convex. Dorsal surface with head, pronotum and elytron smooth, shiny. Color yellow except pronotum with large, dark brown basomedian macula extended 4/5 distance to anterior pronotal margin, anterior margin of macula arcuate, entire, macula occupying most of pronotum, only anterior 1/5 and lateral 1/5 yellow; elytron brown with 4 small, yellow spots, without mediolateral spot, humeral spot small, triangular, scutellar spot round, discal spot round, apical spot obliquely triangular ( Fig. 289 ); ventral surface with head, prosternum, meso- and metaventrite yellowish brown; abdomen yellowish brown, paler toward lateral margins. Head punctures coarse, separated by a diameter or less, each puncture about as large as 2 eye facets; 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 twice a diameter; metaventral punctures much larger than on elytron, separated by less than to about a diameter medially, larger and separated by less than a diameter in lateral 1/3. Clypeus slightly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 5 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 narrow, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with wide 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 with setal tuft. Basal abdominal ventrite with setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex, ventrite and ventrites 2-3 with dense, long pubescence and coarse, dense punctures medially becoming denser laterally; ventrites 4-6 pubescent throughout, punctures fine, dense; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex weakly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 3/4 as long as paramere, asymmetrical, sides weakly convergent from base to rounded apex; paramere Pvl, slender, lower margin produced in apical 1/2, lower margin curved upward to rounded apex ( Fig. 290, 291 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm long, wide, apex slightly rounded, outer arm short and about as long as inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 292, 293 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Brazil, Rio de Jan. , Acc.No. 2966, Oct. ( CMNH).

Geographical distribution. Brazil.

Remarks. This species is similar to many other Cyrea species in dorsal color pattern, but is the only species in the devillii group with a combination of pronotal macula large, apically arcuate, occupying most of pronotal surface; elytron lacking mediolateral spot; and setal tufts on metaventrite and basal abdominal ventrite.
