Systematic placement of some taxa in the family Galumnidae (Acari, Oribatida) Author Ermilov, Sergey G.

(Fig. 6) The species Acrogalumna brevisetosa was described by Bayartogtokh and Weigmann (2005) from Mongolia . The authors included it in the genus Acrogalumna Grandjean, 1956 . However, representatives of Acrogalumna differ from those of Allogalumna by the presence of sexual dimorphism in the morphology of medial pore (versus sexual dimorphism absent). We studied the morphology of the holotype and paratypes of Ac. brevisetosa and established that medial pore always absent absolutely in female and male. Hence, based on our research and generic diagnosis of Allogalumna (see Ermilov et al . 2013 ), we propose the following change: Allogalumna brevisetosa ( Bayartogtokh & Weigmann, 2005 ) comb. nov. In the original description, Bayartogtokh and Weigmann (2005) stated that the sublamellar line is present, weakly developed, but the authors did not show it in the illustration ( Fig. 1 b; p. 90). Therefore, we studied the type specimens again, and clarified that line S is clearly developed in this species.
