Diagnosis. Distinguished from all the previous species by the concave posterior margin of the saccus, narrowly V-shaped, with the corner of the projection nearly right angle (Pl. 15: Fig. 1; see arrow). Along with C. barbara sp. nov. and C. mariana sp. nov., C. stigmatica shows all wings more rounded and a lighter brown stripe running over M 2 within the cell and then continuing between Rs4 and M 1 (Pl. 3: Figs 1–4), instead of dark brown in the two former species (Pl. 3: Figs 6–9, 13–14). This contrast facilitates identification.

Male (Pl. 3: Figs 1–4, Pl. 10: Fig. 11). Forewing length: 15–20 mm, wingspan: 32–42 mm. Epiphysis present.

Male genitalia (Pl. 15: Fig. 1, Pl. 19: Fig. 11). Saccus with posterior edge concave, slightly V-shaped, with corner of projection at right angle. Tergal lobes extended posteriorly. Pseudotegumen reinforced anteriorly and posteriorly. Fultura inferior as long as wide, bilobed dorsally. Valvae with tip rounded.

Female (Pl. 3: Fig. 5, Pl. 13: Fig. 5). Forewing length: 23–35 mm, wingspan: 44–64 mm.

Female genitalia (Pl. 23: Fig. 5, Pl. 24: Fig. 5). Lamella antevaginalis slightly sclerotized, only its latero-posterior dorsal edge densely sclerotised, forming a triangular process; each well separated medially by a shallow bilobed projection, slightly sclerotised and setose, antero-ventrally. Ductus bursae tubular, ca. 2.5× longer than pyriform corpus bursae.

Distribution. Central-southern Paraná to eastern Rio Grande do Sul, southern Brazil at altitudes between about 500 to 1350 m (Pl. 25: Fig. 2).

Remarks. This species is relatively common in the northeastern Santa Catarina from mid to late summer. While males have a highly variable FW ornamentation, females do not. The species is sympatric and synchronic with C. monoargenteus and C. ybyra within this species-group.

The original description is an image of the adult female with few details about FW ornamentation. The male and female genitalia are here figured for the first time.
