36. Cyrea bessie Canepari and Gordon , new species

Description. Male. Length 2.3 mm, width 1.7 mm; body elongate oval, convex. Dorsal surface with head weakly alutaceous, slightly shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with narrow, light brown basomedian macula with rectangular anterior projection on each side of middle extended 2/3 distance to anterior pronotal margin, small, obscure rounded spot present on each side near lateral pronotal margin; elytron pale brown with 5 large, yellow spots arranged in rows of 2 each with apical spot, humeral spot elongate triangular, nearly reaching mediolateral spot, scutellar spot rounded, mediolateral spot oval, slightly projected inward, discal spot oval, apical spot transversely rectangular, anterior border of spot entire ( Fig. 198 ); ventral surface with head, prosternum, meso- and metaventrite pale reddish brown; abdomen yellow. Head punctures small, separated by less than a diameter, each puncture about as large as 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 slightly larger than on elytron, separated by a diameter or less 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 4 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 apically, convergent, jointed at basal 1/6 of prosternum, connected to 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, ventrites 1-2 with dense, long pubescence and coarse, dense punctures; ventrites 3-6 with long, dense pubescence throughout, punctures fine, dense; 5th ventrite 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 about as long as paramere, asymmetrical, sides slightly convergent from base to apical 1/4, apical 1/4 curved to abruptly rounded apex; paramere Pem, widened from narrow base to wide apex, upper margin nearly straight, lower margin strongly curved, apex slightly oblique, weakly emarginate ( Fig. 199, 200 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm long, slender, abruptly narrowed medially, apex obliquely truncate, outer arm wider and longer than inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 102 , 202 ).

Female. Similar to male except head with clypeus and apex of frons yellowish brown, pronotum with rectangular anterior projections extended to apical pronotal margin. Genitalia with spermathecal capsule short, slightly bent medially, narrowed from base to acute apex of cornu; bursal cap oval with 2 slender, sclerotized arms, apical strut short, slender, slightly widened in apical 1/3 ( Fig. 203 ).

Variation. Length 2.0 to 2.4 mm, with 1.6 to 1.8 mm. Female pronotum may have the rectangular anterior arms of basomedian macula wide, leaving only a narrow, elongate yellow median spot.

Type material. Holotype male; Brazil, Chapada , ACC.No.2966, April. ( CMNH) . Paratypes; 4, same data as holotype except additional month of “Nov.” ( CMNH) .

Geographical distribution. Brazil.

Remarks. This species is the only pale brown and yellow taxon within this group, and quite distinctive on that basis. The paramere of the male genitalia is not as highly modified as in most of the other species, but distinctive to C. bessie .
