Cibyra bruna, Mielke & Grehan & Koike, 2025

Mielke, Carlos G. C., Grehan, John R. & Koike, Ricardo M., 2025, Review of the genus Cibyra Walker (Lepidoptera: Hepialoidea: Hepialidae) with descriptions of twenty-four new species from Brazil and Argentina, Zootaxa 5709 (1), pp. 1-74 : 59-61

Cibyra pluriargenteus species-group

Three species, with C. bruna sp. nov. allopatric to the south (Pl. 26, Fig. 2 ) and adjacent to the southern limits of C. simone sp. nov. whose range extends north and overlaps the central distribution of C. pluriargenteus (Plate 31, Fig. 1a ). This arrangement is consistent with an originally allopatric divergence of all three species, where C. simone sp. nov. extended along coastal regions while C. pluriargenteus extends further inland and to the north (Plate 31, Fig. 1b ).
