Aletretia peraffinis Breuning, 1940: 153 . Syn. nov.

Rosalba peraffinis; Breuning, 1960: 174 (cat.); 1971: 228; Monné, 2005:310 (cat.); Monné et al., 2010: 247 (distr.); Monné et al., 2012: 56 (distr.).

Breuning (1971) separated R. apprΟximata from R. peraffinis in his key as follows (translated):

“9. The outer apical angle of the elytra sometimes spiny, but not stretched in lobe…10 [conducting to R. peraffinis] / This angle stretched into a lobe sometimes very small… 14 [conducting to R. apprΟximata].”

Nevertheless, examination of the type series of R. apprΟximata and several specimens belonging to MZSP collection, as well as photograph of the holotype of R. peraffinis, show that the difference pointed out by Breuning (1971) is just specific variation. There are no other differences separating these species. Thus, we synonymize R. peraffinis with R. apprΟximata.
