This subspecies has been characterised both morphologically and genetically by Albrecht et al. (2008). We examined the copulatory apparatus of two specimens and found that its structure is typical for the genus. Both praeputium and penis sheath are light-coloured; praeuputium is substantially larger than the penis sheath (see Fig. 8M), the ratios between their lengths are 1.42 and 1.46, respectively.

A. r. relicta inhabits Ohrid Lake (Albania and Macedonia), as well the Drin system, at least upstream to the dam Globočičko, approximately 15 km N of the lake (Albrecht et al. 2008).
