78. Cyrea stacy Canepari and Gordon , new species

Description. Male holotype. Length 2.8 mm, width 2.4 mm; body rounded, convex. Dorsal surface smooth, shiny. Color yellow except pronotum with 5 small dark brown spots, 1 triangular spot on each side of middle near base, 1 elongate oval basal spot anterior to scutellum, and 1 small, triangular spot on each side just anterior to middle; elytron with 4 small, round, dark brown spots, 1 spot on humeral callus, 1 discal spot near suture anterior to middle of elytron, 1 mediolateral spot near lateral margin at apical declivity, and 1 spot at middle of apical declivity ( Fig. 431 ); ventral surface with head, median 1/3 of prosternum, meso- and metaventrites dark brown; abdomen yellow except median 1/3 of ventrites 1-4 yellowish brown. Head punctures small, separated by a diameter or less, each puncture slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by less than to 2 times a diameter, elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than on elytron, separated by less than a diameter medially, slightly larger and nearly contiguous in lateral 1/3. Clypeus slightly emarginate apically, nearly truncate, 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 straight, 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 arcuate, smooth, sponda extended beyond angle. Carinae on prosternal process narrowly separated at apex, convergent, apical 1/2 not visible. 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 with anterior margin oblique, widely separated from posterior margin of ventrite 4, depressed in median 1/3, apex weakly emarginate; 6th ventrite medially depressed, apex slightly emarginate with lateral angle rounded. Apical tergite finely, densely punctured, apex feebly emarginate. Genitalia with basal lobe 3/4 as long as paramere, asymmetrical, sides curved, not convergent from base to broadly rounded apex; paramere Psc, equal in width from base to apex, lower angle of apex produced ( Fig. 432, 433 ); sipho curved in basal 1/2, without visible alae, basal capsule with inner arm long, slender, inner margin sinuate, apex rounded, outer arm narrower and about as long as inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 434, 435 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Bolivia, Las Juntas, Steinbach Coll., C. M. Acc. 5053, Dec. 1913. ( CMNH).

Geographical distribution. Bolivia.

Remarks. Cyrea stacy has a unique dorsal color pattern that will serve to distinguish it from other Cyrea species. It also has a Bolivian type locality which is somewhat unusual.
