Valvae robust, thumb-like, inner surface with ridges. Distal bladder of phallus, when everted, rounded with two subtle protrusions dorsally and two ventrally.

Female ( Pl. 6 View PLATE 6 : Figs 5, 7–8 View PLATE 1 , Pl. 13: Fig. 10 View PLATE 1 ). Forewing length: 18–24 mm, wingspan: 37–48 mm.

Female genitalia (Pl. 23: Fig. 10 View PLATE 1 , Pl. 24: Fig. 10 View PLATE 1 ). Lamella antevaginalis mesally separated into two plates, except by short and narrow antero-ventral fusion; latero-posterior dorsal edge densely sclerotised, digitiform. Ductus bursae 1/4 length of pyriform corpus bursae.

Distribution. Central-southern Paraná to northeastern Rio Grande do Sul, southern Brazil, at altitudes between about 1000 and 1400 m (Pl. 27: Fig. 1 View PLATE 1 ).

Remarks. Cibyra verresi can often be observed at light traps in late summer. In contrast to other species of the group, the FW ground colour varies from dark to orangish-brown, although the second phenotype is much less frequent. Only sympatric and synchronic with C. dorita within this species-group. Endemic to higher areas of Paraná to the south and Santa Catarina to the southeast.
