Specimens of Baetis (Rhodobaetis) braaschi Zimmermann, 1980 from the three distant geographic regions (Crimean Peninsula, Eastern Ukraine and Caucasus) are investigated and compared using a methodological approach combining morphological and molecular (partial mtDNA COI sequences) data. Intraspecific variability in several morphological characters is recognized and described, whereas COI sequences are found to be very uniform. The amount and distribution of the changes of COI sequences do not follow the pattern of morphological variability and/or geographic origin of the specimens. This indicates that analysis of the changes in the COI sequence can contradict the pattern of morphological characters commonly used for the discrimination of the individual Rhodobaetis species. As a basis for the future taxonomic changes concerning subgenus Rhodobaetis, it is advised (where possible) to critically evaluate both molecular and morphological data.
