Diagnosis. Similar to C. tessellata and C. regina sp. nov., but distinguished by: i) the proportionately larger male genitalia apparatus (1.3× larger; Pl. 14: Fig. 6 ), ii) pseudotegumen anteriorly not reinforced as in C. regina sp. nov. (reinforced in C. tessellata (Pl. 14: Fig. 5 ; see arrow)), iii) fultura inferior twice as wide as long (as wide as long in C. tessellata and C. regina sp. nov.), and iv) posterior margin of the saccus notably concave with a mesal indentation (Pl. 14: Fig. 6 ; see arrows) whereas slightly concave in C. tessellata and C. regina sp. nov. (Pl. 14: Figs 5, 8 ). All species are reciprocally allopatric.

Description. Male ( Pl. 2 : Figs 5, 7 , Pl. 10: Fig. 6 ). Forewing length: 12–20 mm, wingspan: 27–39 mm. Epiphysis present.

Male genitalia (Pl. 14: Fig. 6 , Pl. 19: Fig. 6 ). Saccus with concave posterior edge concave, with clear indentation that accommodates valva. Tergal lobe flat. Pseudotegumen anteriorly thin, posteriorly reinforced. Fultura inferior dorsally bilobed, rectangular, twice as wide as long. Valvae distally rounded.

Female ( Pl. 2 : Fig. 4 ). Forewing length: 30 mm, wingspan: 60 mm. Epiphysis present.

Female genitalia. Not dissected.

Distribution. Endemic to the Serra da Mantiqueira and Serra do Mar in the states of Rio de Janeiro, Minas Gerais, and São Paulo , southeastern Brazil, at altitudes between about 1500 and 2000 m (Pl. 25: Fig. 2 ).

Etymology. Homonym in honour of Elyana G. Joerke, feminine. It is treated as a noun in the nominative singular in apposition.

Remarks. Sympatric and synchronic only to C. mariana sp. nov. within the species-group.
