Editorial note On the publication “On the current state of taxonomy of the Baikal Lake amphipods (Crustacea, Amphipoda) and the typological ways of constructing their system” by V.V. Takhteev In this issue we present an extensive article prepared by Prof. Vadim V. Takhteev, which is based on his long time effort in the study of diversity of amphipods in Lake Baikal and its watershed. This paper is highly polemical and may even seem either archaic or heretical in the time of domination of the phylogenetic paradigms in systematics. The author advocates classical morphological taxonomy, which own tradition, methods (disregarding whether we call it typology or not) and the language are significantly older than the modern phylogenetic approach.
