Paratypes (in total 10 ♂): Brazil. Minas Gerais. Diamantina, Guinda 7 km SW, 1288 m: 4 ♂, 25.X.1989, C. Mielke leg. ( CGCM 41.222, 41.493, 41.521, 41.581; CGCM). Santana do Riacho, Alto Palácio, 1336 m: 4 ♂, Rio Miguel Quicé, 3–8.X.1959, Travassos & Pearson leg. (Z 4744, 47464750, 4753; CEIOC); 1 ♂, 13.X.2023, E. Joerke & C. Mielke leg. ( CGCM 48.372; CEIOC). Nova Lima: 1 ♂, 18.XI.1997, ( CGCM 35.670; CGCM).

Diagnosis. This member can be easily distinguished from all congenerics by the configuration of the FW postdiscal line, which is dark grey within or without a light grey band, and with or without a whitish-grey inner area. The male genitalia are similar to the next two species and are discussed under C. volta sp. nov.

Description. Male (Pl. 8: Figs 8–9 , Pl. 12: Fig. 3 ). Forewing length: 11–17 mm, wingspan: 26–34 mm. Epiphysis absent.

Male genitalia (Pl. 17: Fig. 7 , Pl. 21: Fig. 7 ). Tergal lobes protruded posteriorly. Saccus with posterior edge V-shaped mesally. Tegumen slightly sinuate. Pseudotegumen expanded ventrally, ribbed ventro-anteriorly. Fultura inferior cup-shaped, slightly wider than longer, constricted laterally, distally bilobed.

Female. Unknown.

Distribution. All records of the new species come from upland habitats (above 1200 m) in central and southeastern Minas Gerais, southeastern Brazil, where grasslands are associated with forest in Brazil (Pl. 28: Fig. 2 ).

Etymology. Homonym in honour of Agnès Porion, feminine. It is treated as a noun in the nominative singular in apposition.

Remarks. As the previous species, the small type series has revealed different phenotypes, especially variation in FW ground colour, ranging between orangish-brown and brown. Only sympatric and synchronic with C. alina sp. nov.
