98. Cyrea dora Canepari and Gordon , new species

Description. Male holotype. Length 3.5 mm, width 2.2 mm; body elongate, slender, essentially parallel sided. Dorsal surface with head slightly alutaceous, shiny, pronotum and elytron smooth, shiny. Color yellow except head black, pronotum black except lateral 1/8 yellow; elytron yellow with lateral margin of apical declivity and apex narrowly bordered with black, sutural margin with wide, irregular black vitta, large, wide black macula on apical declivity connected to sutural border and lateral margin, small, irregularly rounded, black spot posterior to humerus ( Fig. 543 ); ventral surface with head, prosternum, meso- and metaventrites black; legs with femur black; abdomen dark brown. Head punctures fine, separated by less than a diameter, each puncture about as large as 3 eye facets; 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 3 times a diameter; metaventral punctures about as large as on elytron medially, separated by a diameter or less, becoming larger and separated by less than a diameter toward lateral margin. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, black. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin weakly curved, basal margin without trace of bordering line medially. Epipleuron narrow, feebly grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, basal tooth absent, sponda distinctly extended beyond protibial margin ( Fig. 544 ). Carinae on prosternal process widely separated at apex, convergent toward base, joined almost at base of prosternum, connected to base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened medially, extended forward at apex, ventrite with sparse, short pubescence and fine, sparse punctures; ventrites 2-6 pubescent throughout, punctures fine, dense; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite slightly depressed medially, apex shallowly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe nearly as long as paramere, slender, symmetrical, sides very slightly convergent from base to apical 1/6, curved to rounded apex in apical 1/6; paramere Psc, wide throughout, apex rounded ( Fig. 545, 546 ); sipho robust, strongly curved in basal 2/3, with visible alae, basal capsule distinctly sclerotized, inner arm short, narrow, weakly bifid apically, outer arm wider, longer than inner arm, with accessory piece, basal border abruptly emarginate ( Fig. 547, 548 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Argentina, prov. San Luis, San Gerónimo , dic 1972, leg. G. Williner, Coleccion J.E. Barriga, Chile 116927. ( JEBC).

Geographical distribution. Argentina.

Remarks. Cyrea dora is distinctive within this genus because of the elongate, parallel sided body form and elytral color pattern. It bears some resemblance to C. lucy in both regards, but the latter species lacks an abdomen.
