Diagnosis. Only member of the species-group without an epiphysis. Further recognized by the combination of the following characters: i) contrasting colour of the anterior portion of the postdiscal band on the male FW ( Pl. 2 View PLATE 2 : Fig. 2 View PLATE 1 ), ii) transverse stigma on the male FW, and iii) posterior margin of saccus with a slight lateral indentation (Pl. 14: Fig. 4 View PLATE 1 ).

Male ( Pl. 2 View PLATE 2 : Fig. 2 View PLATE 1 , Pl. 10: Fig. 4 View PLATE 1 ). Forewing length: 11–17 mm; wingspan: 22–33 mm (see Mielke 2014).

Male genitalia (Pl. 14: Fig. 4 View PLATE 1 , Pl. 19: Fig. 4 View PLATE 1 ). For details, see Mielke (2014).

Female ( Pl. 2 View PLATE 2 : Fig. 1 View PLATE 1 , Pl. 13: Fig. 4 View PLATE 1 ). Forewing length: 18–29 mm; wingspan 37–54 mm (see Mielke 2014).

Female genitalia ( Pl. 23: Fig. 4 View PLATE 1 , Pl. 24: Fig. 4 View PLATE 1 ). For details, see Mielke (2014: Fig. 9 View PLATE 1 ).

Distribution. Southeastern São Paulo to southeastern Santa Catarina , southeastern and southern Brazil, at altitudes about 800 to 1400 m (Pl. 25: Fig. 2 View PLATE 1 ).

Remarks. The contrasting postdiscal band on the male FW, along with a lighter brown and relatively uniform (not mottled) ground colour, makes its identification easier without dissection. This species does not vary considerably in most specimens. Along with C. meridionalis and C. ochracea , this is a relatively common species in late spring to mid-summer in semi-deciduous forest. Sympatric and synchronic to C. barbara sp. nov., C. denise sp. nov., C. stigmatica , C. tessellata , and C. ybyra within this species-group.
