76. Cyrea marion Canepari and Gordon , new species

Description. Male holotype. Length 2.5 mm, width 2.0 mm; body oval, convex. Dorsal surface with head alutaceous, dull, pronotum weakly alutaceous, feebly shiny, elytron smooth, shiny. Color yellow except pronotum with long, black basomedian macula extended 2/3 distance to anterior pronotal margin, macula with apical border entire; elytron with dark brown border on all margins, sutural border wide, sinuate, widened area at basal 1/4 and on apical declivity, lateral margin with large, triangular spot on humeral angle and small, oval spot at middle ( Fig. 421 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen brownish yellow except median 1/3 of ventrites 1-4 brown. Head punctures small, separated by a diameter or less, each puncture slightly larger than an eye facet; pronotal punctures slightly larger than head punctures, separated by 1 to 2 times a diameter, elytral punctures larger than on pronotum, separated by 1 to 2 times a diameter; metaventral punctures larger than on elytron, separated by about a diameter 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 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin straight, basal margin without trace of bordering line medially. Epipleuron wide, grooved, 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 widely separated at apex, convergent, joined at basal 1/6 of prosternum, connected to prosternal base by single carina. Metaventrite with setal tuft. Basal abdominal ventrite with sparse 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 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 weakly emarginate; 6th ventrite medially depressed, apex emarginate with lateral angle produced, abruptly rounded. Apical tergite finely, densely punctured, apex broadly emarginate. Genitalia with basal lobe slightly shorter than paramere, asymmetrical, wide in basal 2/3, sides curved, apical 1/3 narrowed, apex obliquely truncate; paramere Psc, slightly widened from base to apex, lower angle of apex produced ( Fig. 422, 423 ); sipho curved in basal 1/2, without visible alae, basal capsule with inner arm short, slender, apex curved, outer arm wider and longer than inner arm, with accessory piece, basal border broadly, deeply emarginate ( Fig. 423, 424 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Brazil, Chapada, Acc.No. 2966, Nov. ( CMNH).

Geographical distribution. Brazil.

Remarks. This species has an unusual dorsal color pattern that is quite distinctive. Male genitalia are not exactly typical of the tessulata group in that the basal lobe is narrowed near apex and the apex is apically truncate.
