Type material. Holotype ♂ ( Pl. 3 View PLATE 3 : Fig. 13 View PLATE 2 ): / BRAZIL — Santa Catarina (SC) , Urubici , Santa Bárbara, 1360 m, 1.-3.II.2019, C. Mielke & E. Joerke leg., 28°8'30.70"S, 49°38'6.84"W / 39.896 Col. C. Mielke/ DZ 52.688/ HOLOTYPUS, Cibyra barbara C. Mielke, Grehan & Koike, 2024 / ( DZUP).

Paratypes (in total 2 ♂ 1 ♀). Brazil. Santa Catarina. Same locality and collector as holotype: 1 ♂, 1–3.II.1989 ( CGCM 38.574 ; CGCM); 1 ♂, 8.I.1992 ( CGCM 44.164 ; CGCM). Rio Grande do Sul. São José dos Ausentes, Silveiras, 1200 m: 1 ♀, 28–31.I.2000, A. Moser leg. ( CGCM 42.783 [ HM430361 View Materials ]; CGCM) .

Diagnosis. The new species is distinguishable from the previous only by the male genitalia. In C. mariana sp. nov. the mesal portion of the posterior margin of the saccus is pronounced (Pl. 15: Fig. 2 View PLATE 1 ; see arrow), while in C. barbara sp. nov. it is barely distinguished and 1.2× longer than in C. mariana sp. nov. (Pl. 15: Fig. 3 View PLATE 1 ; see arrow).

Description. Male ( Pl. 3 View PLATE 3 : Figs 13–14 View PLATE 2 , Pl. 10: Fig. 13 View PLATE 2 ). Forewing length: 14–15 mm, wingspan: 31–33 mm. Epiphysis present.

Male genitalia (Pl. 15: Fig. 3 View PLATE 1 , Pl. 19: Fig. 13 View PLATE 2 ). Saccus with its posterior margin straight, mesal portion barely 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. 12 View PLATE 1 ). Forewing length: 24 mm, wingspan: 51 mm. Epiphysis present.

Female genitalia. Not dissected.

Distribution. Known from the Serra Geral in two localities only in the southeastern Santa Catarina and northeastern Rio Grande do Sul, southern Brazil, at altitudes between about 1200 and 1400 m (Pl. 25: Fig. 2 View PLATE 1 ).

Etymology. Homonym in honour of Bárbara P. Sicuro, feminine. It is treated as a noun in the nominative singular in apposition.

Remarks. As for the previous species, it is relatively scarce considering the efforts applied to discovering its distribution. It is sympatric and synchronic with C. monoargenteus and C. ybyra within this species-group and allopatric to its most similar species, C. mariana sp. nov.

c) Species-group: yungas . One species: C. yungas .

Defined by the phallus, everted, as a distal bladder-like vesica with two antero-ventral diverticula (Pl. 19: Fig. 14 View PLATE 2 ). In addition, by: i) male sternite VIII uniformly sclerotised, shield-shaped; ii) tegumen extended beyond articulation with saccus; iii) posterior margin of saccus simple; iv) tergal lobes somewhat flattened, resting over the pseudotegumen; v) pseudotegumen expanded posteriorly, then folded outwards, and expanded mesally; vi) fultura inferior folded inward posteriorly, and; vi) valvae digitiform and ribbed.

Distribution. Bolivia (Pl. 28: Fig. 1 View PLATE 1 ).
