Pergalumna (Bigalumna) rimosa ( Mahunka & Mahunka-Papp, 2009) comb. nov.

The subgenus Galumna (Bigalumna) was proposed by Mahunka and Mahunka-Papp (2009) with Galumna (Bigalumna) rimosa ( Mahunka & Mahunka-Papp, 2009 as type species from Kenya. These authors included this subgenus in the genus Galumna Heyden, 1826 . However, all representatives of the latter genus have lamellar setae inserted between lamellar and sublamellar lines. We studied the morphology of paratypes of G. (B.) rimosa and clarified that lamellar setae are inserted between lamellar lines, and generally, this species has all typical characteristics of the genus Pergalumna Grandjean, 1936 . Based on the above statement and generic diagnosis of Pergalumna (see Ermilov et al. 2013), we propose the following taxonomic alterations: a) Pergalumna (Bigalumna) Mahunka & Mahunka-Papp, 2009 stat. nov., b) Pergalumna (Bigalumna) rimosa ( Mahunka & Mahunka-Papp, 2009) comb. nov.
