77. Cyrea dana Canepari and Gordon , new species

Description. Male holotype. Length 2.4 mm, width 1.8 mm; body oval, convex. Dorsal surface with head alutaceous, dull, pronotum weakly alutaceous, shiny, elytron smooth, shiny. Color yellow except pronotum with short, pale brown basal macula extended 1/6 distance to anterior pronotal margin, with pale brown, triangular spot on each side of middle; elytron with large, pale brown macula medially, basal 1/5 of elytron irregularly yellow, apical 1/4 irregularly yellow with median projection of brown macula ( Fig. 426 ); ventral surface with head, prosternum, meso- and metaventrites pale brownish yellow; abdomen yellow. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures larger than head punctures, separated by a diameter or less, elytral punctures larger than on pronotum, separated by a diameter or less to twice a diameter; metaventral punctures larger than on elytron, separated by less than a diameter medially, slightly larger and separated by less than a diameter in lateral 1/3. Clypeus apically truncate, 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, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin straight, smooth, sponda not extended beyond angle. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/5 of prosternum, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without 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 slightly emarginate with lateral angle abruptly rounded. Apical tergite finely, densely punctured, apex widely, feebly emarginate. Genitalia with basal lobe 2/3 as long as paramere, asymmetrical, sides slightly curved, convergent from base to abruptly rounded apex; paramere Psc, same width from base to apex, lower angle of apex produced ( Fig. 427, 428 ); sipho curved in basal 2/3, without visible alae, basal capsule with inner arm short, wide, apically emarginate, outer arm short, narrower and about same length as inner arm, with accessory piece, basal border shallowly emarginate ( Fig. 429, 430 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Colombia, Minca, Acc.No. 1990, June. ( CMNH).

Geographical distribution. Colombia.

Remarks. This species has a dorsal color pattern that is difficult to recognize because the yellow background and pale brown macula are not well differentiated. Thus far, that pattern seems to be unique within the genus and may serve to identify C. dana . Male genitalia are not particularly distinctive, although the basal lobe is unusually short.
