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

Cibyra monoargenteus species-group

Ten species, of which three have parallel southeast-northeast distributions, with C. monoargenteus nested within the slightly more extended distributions of C. stigmatica (to the northwest), and C. tessellata (to the northeast). At the southern end of C. monoargenteus and C. stigmatica is a cluster of two more localized species— C. ybyra ( 1,000 –1,400 m) and C. barbara sp. nov. ( 1,200 –1,400 m) that together comprise a track between the Serra Geral of southeastern Santa Catarina and northeastern Rio Grande do Sul. Further northeast of C. tessellata are two allopatric clusters, each comprising species that are sympatric with each other at least part of their respective ranges of two overlapping species in each: C. elyana sp. nov. and C. mariana sp. nov., and C. jane sp. nov. and C. regina sp. nov. (Pl. 30, Figs 2a–b ). In this species-group there is both allopatry and geographic overlap, the latter indicating considerable range expansion for the widespread species and more localized range expansion for the localized species under an allopatric speciation model. This geographic dispersion notwithstanding, the distributions are consistent with original allopatry of species as indicated in Pl. 30. Fig. 2b .
