Diagnosis. This species is most similar to C. huarpe and C. jaguense. It can be differentiated from the latter by the shorter malar space, ~1/2 as long as wide versus ~2/3 as long as wide. It can be differentiated from C. huarpe by having at least some metapostnotal striate reaching the posterior margin and in the striae of the metatpostnotum, at least some of which reach the posterior margin and T1 strongly imbricate.
Description. Female. Length 7.5 mm; forewing length 4.9 mm, head width 1.7 mm.
Head: 1.2 X as long as wide, 80:67; black, orange mark below anterior tentorial pit, extending to apical 1/3 of malar space. Face below antennae shining, weakly imbricate, most strongly on lower 1/3 of supraclypeal area, upper 1/2 of clypeus, and around antennal sockets; face below antennae deeply punctate, i=1–3 d; frontal area densely and evenly punctate, i<d; facial fovea shiny, punctures smaller and sparser than on adjacent frontal area. Malar space slightly more than half as long as wide (12:21). Longest hairs on face above antennal sockets, 1.3 MOD, longer on vertex <2 MOD; genal beard 3 MOD.
Mesosoma: Pronotum and anteromedial portion of mesoscutum doubly punctate, small punctures dense, i~d, larger punctures scattered; rest of mesoscutum slightly dull and imbricate, punctures distinct, i=1–1.5 d, smaller anteromedially, i<d; mesoscutellum shiny, punctures distinct, i=0.5–2 d with few scattered minute punctures; metanotum slightly dull, anterior punctures small and dense, i<d, posteriorly punctures larger and sparser, i=1–2 d; mesepisternum imbricate with numerous minute punctures (i=1–2 d) among larger ones, i=1–3 d; metepisternum longitudinally rugosostriate above, coarsely imbricate below, with dense punctures. Mesoscutum lacking long hairs, hairs <0.5 MOD; mesepisternum with longest hairs ventrally ~1.5 MOD. Stigma shorter than marginal cell on costal margin, 55:75; apex of marginal cell abruptly curving from anterior wing margin, almost truncate; distal stigma perpendicular just apical to first submarginal crossvein. Metapostnotum with most striae long, nearly reaching posterior margin of metapostnotum, median stria reaching posterior margin; lateral surface of propodeum imbricate, punctures shallow, large at midlength dorsally, smaller elsewhere.
Metasoma: terga shiny, shallowly imbricate; T1 doubly punctate, minute punctures more abundant than large ones on disc, large punctures evenly spaced, i~d; minute punctures decreasing in abundance on T4–T5, i=1–2 d, mainly restricted to apical impressed areas.
Male: unknown. Material studied. Holotype female: ARGENTINA, San Juan, Leoncito, Feb. 14. ii., 1966. C.C. Porter [MCZ] [See Figs. 184–185 for distribution map]. Etymology. The species is named after the historical province of Cuyo, which encompassed the present day provinces of San Luis, Mendoza and the home province for the new species, San Juan.
