Salesópolis, Boraceia, 800 m: 1 ♂, 1 ♀, 24.I.1968, Ric., Travassos & Travassos F. leg. (MZUSP) . Paraná. Quatro Barras, Banhado, 800 m: 1 ♂, 7.II.1970, V. O. Becker leg. (CGCM 46.774; CGCM) ; 1 ♂, 27.II.1970, Laroca & V.O. Becker (CGCM 15.535; CGCM) .

Diagnosis. Easily distinguished from all congeners in the pluriargenteus species-group by the shorter antennae in males due to smaller distances between each flagellomere (Pl. 5: Figs 8–11), and the tergal lobes are enlarged basally only, without any process (Pl. 16: Fig. 3; see upper arrow). The valvae are broader and much less apically curved (Pl. 16: Fig. 3; see lower arrow).

Description. Male (Pl. 5: Figs 8–11, Pl. 11: Fig. 7). Forewing length: 13–15 mm, wingspan: 29–32 mm. Epiphysis present.

Male genitalia. (Pl. 16: Fig. 3, Pl. 20: Fig. 9). Tergal lobes basally enlarged basally. Tegumen slightly S-shaped. Pseudotegumen projected postero-dorsally, ventrally expanded, reinforced, and ribbed medially. Fultura inferior bilobed dorsally, 1.2× wide as long.

Female (Pl. 5: Fig. 12). Forewing length: 23 mm, wingspan: 46 mm. Epiphysis present.

Female genitalia. Not dissected.

Distribution. Serra da Mantiqueira and Serra do Mar in the states of Minas Gerais and São Paulo to eastern Paraná, southeastern and southern Brazil, at altitudes ranging between approximately 800 to 1898 m (Pl. 26: Fig. 2).

Etymology. Homonym in honour of Simone L. da Costa, feminine. It is treated as a noun in the nominative singular in apposition.

Remarks. Despite intensive collecting efforts in areas where C. simone sp. nov. is known to be present, few specimens are known. Records from late spring to late summer suggest a broad flight period. It is only sympatric and synchronic with C. pluriargenteus within this species-group.
