Cibyra ykeyra : Mielke (2015: 13; figs 3a–b ( holotype ♂ dorsal/ventral), 4–6 ( ♂ dorsal), 7a–b ( ♀ female), 17 ( holotype ♂ abdominal segment VIII), 18 ( holotype ♂ gen.), 19 ( holotype phallus), 23 (geographical distribution)); holotype ♂ with the following labels: / Holotypus, Cibyra ykeyra C. Mielke det. 2014/ Brasil, SC, São Bento do Sul, Rio Vermelho, 700 m, 8. I. 2006, I. Rank leg./ CGCM 19.962 / DZ 15.534/ BC-CGCM [BCJX215634]/; DZUP (examined).— Favretto (2016: 72).— Grehan et al. (2023: 78).

Diagnosis. See diagnosis of C. endyra .

Examined material (in total 34 ♂ 1 ♀). Brazil. Same material listed by Mielke (2015): 29 ♂ 1 ♀ (including HT).

Male ( Pl. 4: Figs 13, 15 , Pl. 11: Fig. 2 ). Forewing length: 14–29 mm, wingspan: 29–57 mm (see Mielke 2015). Epiphysis absent.

Male genitalia (Pl. 15: Fig. 8 , Pl. 20: Fig. 4 ). For details, see Mielke (2015).

Female ( Pl. 4: Fig. 14 ). Forewing length: 32 mm, wingspan: 58 mm (see Mielke 2015).

Female genitalia. Not dissected.

Distribution. Confined to the eastern part of the states of Paraná and Santa Catarina , southern Brazil at altitudes between about 600 and 1100 m (Pl. 26: Fig. 1 ).

Remarks. Along with C. ybyra , C. endyra , and C. hannelore sp. nov., C. ykeyra presents two basic forms - banded as described by Mielke & Casagrande (2013) for C. meridionalis ( Pl. 2 : Fig. 13 ; Pl. 4: Figs 11 , 15–16 ) and a more uniform pattern comprising a subtle orange mottling without clear lines or bands ( Pl. 2 : Fig. 14 ; Pl. 4: Figs 12–13 ). In some specimens with the second phenotype, the post-discal band is distinguishable as in the previous form. It is allopatric to all members within this species-group.
