Paratypes (in total 2 ♂ 1 ♀). Brazil. Santa Catarina. Same locality and collector as holotype: 1 ♂, 1–3.II.1989 (CGCM 38.574; CGCM); 1 ♂, 8.I.1992 (CGCM 44.164; CGCM). Rio Grande do Sul. São José dos Ausentes, Silveiras, 1200 m: 1 ♀, 28–31.I.2000, A. Moser leg. (CGCM 42.783 [HM430361]; CGCM) .

Diagnosis. The new species is distinguishable from the previous only by the male genitalia. In C. mariana sp. nov. the mesal portion of the posterior margin of the saccus is pronounced (Pl. 15: Fig. 2; see arrow), while in C. barbara sp. nov. it is barely distinguished and 1.2× longer than in C. mariana sp. nov. (Pl. 15: Fig. 3; see arrow).

Description. Male (Pl. 3: Figs 13–14, Pl. 10: Fig. 13). Forewing length: 14–15 mm, wingspan: 31–33 mm. Epiphysis present.

Male genitalia (Pl. 15: Fig. 3, Pl. 19: Fig. 13). Saccus with its posterior margin straight, mesal portion barely pronounced. Tergal lobes flattened. Pseudotegumen anteriorly as wide as posteriorly. Fultura inferior bilobed dorsally, trapezoidal, 1.2× wider than long. Valvae with tip rounded.

Female (Pl. 3: Fig. 12). Forewing length: 24 mm, wingspan: 51 mm. Epiphysis present.

Female genitalia. Not dissected.

Distribution. Known from the Serra Geral in two localities only in the southeastern Santa Catarina and northeastern Rio Grande do Sul, southern Brazil, at altitudes between about 1200 and 1400 m (Pl. 25: Fig. 2).

Etymology. Homonym in honour of Bárbara P. Sicuro, feminine. It is treated as a noun in the nominative singular in apposition.

Remarks. As for the previous species, it is relatively scarce considering the efforts applied to discovering its distribution. It is sympatric and synchronic with C. monoargenteus and C. ybyra within this species-group and allopatric to its most similar species, C. mariana sp. nov.
