34. Cyrea willie Canepari and Gordon , new species

Description. Male holotype. Length 3.0 mm, width 2.4 mm; body elongate oval, convex. Dorsal surface with head alutaceous, dull, pronotum faintly alutaceous, shiny, elytron smooth, shiny. Color yellow except pronotum with large black basomedian macula extended 5/6 distance to anterior pronotal margin, macula with anterior border smoothly arcuate; elytron black with 5 large, yellow spots arranged in rows of 2 each with apical spot, humeral spot triangular, scutellar spot irregularly rounded, mediolateral spot widely separated from lateral margin of elytron, triangular, discal spot triangular, apical spot transversely oval, anterior border of spot entire ( Fig.188 ); ventral surface with head, prosternum, meso- and metaventrite black; abdomen yellowish brown except median portion of ventrites1-3 dark brown. 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 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 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 wide, grooved, weakly 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 apically, convergent, jointed at basal 1/3 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 1-3 with dense, long pubescence and fine, dense punctures; ventrites 4-6 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 parallel from base to apical 1/4, apical 1/4 abruptly projected on one side; paramere Pem, widened from narrow base to wide apex, upper and lower margins weakly curved, apex weakly emarginate ( Fig. 189, 190 ); sipho strongly curved in basal 3/4, without visible alae, basal capsule with inner arm long, slender, outer arm wider and about as long as inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 191, 192 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; ( Brazil) Fry , Rio Jan., Fry Coll., 1905.100. ( BMNH).

Geographical distribution. Brazil.

Remarks. This species is not easily distinguished on external characters, but the mediolateral spot widely separated from the lateral elytral margin, and presence of setal tufts on both metaventrite and basal abdominal ventrite are somewhat distinctive within this group.
