Diagnosis. The female of this species can be differentiated by the combination of short striae on the metapostnotum and abundant minute punctures among the larger ones on T1. It is most similar to C. jaguense but differs as noted in the diagnosis for that species.
Description. Female. Length 7.0 mm; forewing length 4.6 mm, head width 1.6 mm.
Head: 1.2 X as long as wide, 98:81; black, small orange mark below anterior tentorial pit, and on apical 1/3 of malar space. Face below antennae shining, weakly imbricate, most strongly on lower 1/4 of supraclypeal area and upper 1/3 of clypeus; face below antennae deeply punctate, i=1–4 d; frontal area densely and evenly punctate, i<d; facial fovea shiny, punctures smaller than on adjacent frontal area. Malar space approximately half as long as wide (10:21). Longest hairs on face above antennal sockets, 1.3 MOD, longer on vertex <2 MOD; genal beard <3 MOD.
Mesosoma: Pronotum but not anteromedial portion of mesoscutum doubly punctate, small punctures dense, i~d, larger punctures scattered; rest of mesoscutum somewhat dull, punctures distinct, i=1–1.5 d, smaller anteromedially, i~d; mesoscutellum shiny, punctures distinct, i=0.5–1d with few scattered minute punctures; metanotum somewhat shiny, anterior punctures small and dense, i<d, posteriorly punctures larger and sparser, i=0.5–2 d; mesepisternum with numerous minute punctures among larger ones, i=1–3 d; metepisternum longitudinally rugoso-striate above, coarsely imbricate below, with dense punctures. Mesoscutum lacking long hairs, hairs <0.5 MOD; mesepisternum with longest hairs ventrally ~2 MOD. Stigma shorter than marginal cell on costal margin, 32:45; 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 short, ~1/2 length of metapostnotum except for median stria and few lateral ones; 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, microsculpture absent basal to apical impressed area; minute punctures decreasing in abundance on more successive terga, i=1–2 d.
Male: unknown.
Material studied. Holotype female: ARGENTINA, Mendoza, Uspelleta,[Uspallata] i.1947, Hayward & Willink [MACN] [See Figs. 184–185 for distribution map].
Etymology. The species is named after the Huarpe people, who used to inhabit northern Mendoza and southern San Juan.
Comments. This species is found further south than any other in the subgenus.
