Type material. Holotype ♂ ( Pl. 3 View PLATE 3 : Fig. 6 View PLATE 1 ): / BRAZIL — São Paulo (SP) , Campos do Jordão, Lavrinhas, 1898 m., 24.I.1988 (30), R. Koike leg./ BC-CGCM/ 36.073 Col. C. Mielke/ DZ 52.678/ HOLOTYPUS, Cibyra mariana C. Mielke, Grehan & Koike, 2024 / ( DZUP).

Paratypes (in total 5 ♂ 2 ♀). Brazil. Rio de Janeiro. Itatiaia, Posto Marcão [Agulhas Negras], 2.460 m: 2 ♂, 1 ♀, 10–13.II.2024, C. Mielke & E. Joerke leg. ( CGCM 50.768 , 51.089 , 51.990 ; CEIOC). São Paulo. Same locality as holotype: 1 ♂, 23–24.I.1998, R. Koike leg. ( CGCM 36.013 ; CGCM); 1 ♂, 22–25.I.1992, O. Mielke & Casagrande leg. ( CGCM 7.238 ; CGCM); 1 ♀, 19.I.1989, R. Koike leg. ( CGCM 38.984 ; CGCM); 1 ♂, 15–20.I.1990, H. Thöny leg. ( CGCM 47.662 ; CGCM) .

Diagnosis. The new species, along with the following species, presents a dark brown stripe running over M 2 within the cell and then continuing between Rs4 and M 1 and a preapical and oblique postmedial line reaching the inner margin at 2/3 on the male FW. A similar stripe, although slightly marked, is also observed on the HW of males. The distinction between this and the next species is given under the latter.

Description. Male ( Pl. 3 View PLATE 3 : Figs 6–9 View PLATE 1 , Pl. 10: Fig. 12 View PLATE 1 ). Forewing length: 16–18 mm, wingspan: 32–36 mm. Epiphysis present.

Male genitalia (Pl. 15: Fig. 2 View PLATE 1 , Pl. 19: Fig. 12 View PLATE 1 ). Saccus with its posterior edge straight, posterior portion pronounced. Tergal lobes flattened. Pseudotegumen anteriorly as wide as posteriorly. Fultura inferior bilobed dorsally, trapezoidal, 1.2× wider than long. Valvae with tip rounded.

Female ( Pl. 3 View PLATE 3 : Fig. 10–11 View PLATE 1 , Pl. 13: Fig. 6 View PLATE 1 ). Forewing length: 19–24 mm, wingspan: 39–46 mm. Epiphysis present.

Female genitalia (Pl. 23: Fig. 6 View PLATE 1 , Pl. 24: Fig. 6 View PLATE 1 ). Lamella antevaginalis slightly sclerotised, strongly notched mesally with postero-dorsal edge produced as a triangular tooth each side of the median. Ductus bursae 1/3 as long as pyriform corpus bursae.

Distribution. Known from the Serra da Mantiqueira in São Paulo and Rio de Janeiro states, in southeastern Brazil, at altitudes above 1800 m (Pl. 25: Fig. 2 View PLATE 1 ).

Etymology. Homonym in honour of Mariana F. Maestri, feminine. It is treated as a noun in the nominative singular in apposition.

Remarks. The new species is relatively scarce, considering the extensive collecting efforts over its distribution range. It is sympatric and synchronic with C. elyana sp. nov. only within this species-group.
