Rosalba mediofasciata   ; Breuning, 1960: 174 (cat.); 1971: 231; Monné & Giesbert, 1994: 190 (checklist); Monné, 1994: 7 (cat.); 2005: 310 (cat.); Monné & Hovore, 2006: 229 (checklist); Monné, 2017: 271 (cat.).

Breuning (1971) separated R. bucki   ( Fig. 54 View FIGURES 49–63 ) from his R. mediΟfasciata ( Fig. 71 View FIGURES 64–76 ) in the key as follows (translated): “Third antennal segment slightly longer than scape… mediofasciata   BREUN. / Third antennal segment shorter than scape…… bucki   MELZ.” Actually in the redescription of R. bucki   he pointed out that the antennomere III is slightly shorter than scape. Actually, the information on the length of the antennomere III was not reported in the original description and the angle of the photo of the holotype does not allow seeing the proportions between it and the scape. The range from “slightly shorter” to “slightly longer” is controversial, and can reflect only sexual dimorphism or even specific variations. For example, in the “ typus ” of R. bucki   , the antennomere III is slightly shorter than scape, while in the “cotypus” they have the same length. As we did not find any difference comparing the descriptions and types of R. bucki   with photograph of the holotype of R. mediΟfasciata, we consider the latter as a junior synonym of the former. As strengthening this opinion, the examination of a specimen identified as R. mediΟfasciata in the MZSP collection, that is practically identical to the holotype of the species in color and shape of elytral drawings, has the antennomere III slightly shorter than scape.
