With a strongly developed last whorl and an ovoid aperture. Operculum red. … Penis long, with a very prolonged, pointed top and a weak outgrowth on the left side, which is hardly visible in many specimens.” That the shape of the penes of distinct species-groups look different in Grossuana spp. has already been depicted by Georgiev et. al . (2015). They all have in common the tapered penis-tip which is much slimmer than the rest of the penis (e.g. Fig. 3.2 ). In the southern part of the Bulgarian Rhodope Mountains occurs Grossuana angeltsekovi Glöer & Georgiev 2009 and G. slavyanica Georgiev & Glöer 2013 , thus we have to compare the new species with these ones.
