Description. Male holotype. Length 3.0 mm, width 2.0 mm; body elongate, nearly parallel sided, slightly flattened. Dorsal surface with head, pronotum, elytron somewhat alutaceous, feebly shiny. Color yellow except head, pronotum yellowish red, immaculate; elytron with 2 dark brown vittae, sutural vitta wide, widest posterior to scutellum, narrowed toward elytral apex, apex of vitta continued around apex of elytron, lateral vitta wide, uneven from humeral angle nearly to apex ( Fig. 614 View Figures 608-624 ); ventral surface with head, prosternum, meso- and metaventrites, legs reddish yellow; abdomen yellow. Head punctures fine, separated by a diameter or less, each puncture 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 medially, separated by less than a diameter, 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 short, about 3 eye facets long, angled forward, apically rounded, reddish 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, not descending externally, deeply emarginate for reception of femoral apices. Protibia without oblique angle, outer margin simply grooved for reception of tarsus, basal tooth absent, sponda not extended beyond protibial margin ( Fig. 615 View Figures 608-624 ). Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/8 of prosternum, connected to base with single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite slightly flattened medially, extended forward at apex. Ventrites 1-3 with dense, short pubescence and coarse, sparse punctures; ventrites 4-6 with dense, fine punctures; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex deeply emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe longer than paramere, wide, symmetrical, sides parallel in basal 4/5, apical 1/5 narrowed to rounded apex; paramere Psc, long, narrow, nearly equal in width from base to apex, apex rounded ( Fig. 616, 617 View Figures 608-624 ); sipho robust, strongly curved in basal 1/2, with visible alae in apical 1/8, basal capsule with inner arm short, obliquely triangular, apex acute, outer arm wider and longer than inner arm, with accessory piece, basal border straight ( Fig. 618, 619 View Figures 608-624 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Argentina, prov. Córdoba , depto Calamuchita, El Sauce, feb 1960, leg. M. Viana, Coleccion J.E. Barriga Chile 115478. ( JEBC).

Geographical distribution. Argentina.

Remarks. Cyrea marian is not closely similar to any other Cyrea species. The immaculate, reddish yellow head and pronotum are similar only to those of C. ruizi . The protibia without an oblique angle and basal capsule of male genitalia with outer arm not emarginate are unique to this species.
