Male ( Pl. 6 : Figs 1, 3 , Pl. 11: Fig. 8 ). Forewing length: 11–19 mm, wingspan: 24–37 mm. Epiphysis absent.

Male genitalia (Pl. 16: Fig. 4 , Pl. 21: Fig. 1 ). Tergal lobes triangular, enlarged at base with a meso-posterior triangular process. Saccus expanded anteriorly, posterior edge concave. Tegumen slightly sinuate. Valvae robust, thumb-like, inner surface with ridges. Distal bladder of phallus, when everted, rounded with a dorsal protrusion.

Female ( Pl. 6 : Fig. 2 , Pl. 13: Fig. 9 ). Forewing length: 20–24 mm, wingspan: 43–50 mm.

Female genitalia (Pl. 23: Fig. 9 , Pl. 24: Fig. 9 ). Lamella antevaginalis mesally separated into two plates apart from a minute antero-ventral fusion (Pl. 23: Fig. 9 ; see arrow); mesal corners densely sclerotised, conical, sharply produced. Ductus bursae 1/2 length of pyriform corpus bursae.

Distribution. Southeastern Paraná to northeastern Rio Grande do Sul in southern Brazil (Pl. 27: Fig. 1 ).

Remarks. Irrespective of the quantity of gold markings, the FW, has a very uniform ground colour. Only sympatric and synchronic with C. verresi within this species-group. A single and disjunct record from São Paulo needs confirmation as it expands the northeastern range by about 500 km.
