. The new subgenus name (defined as feminine) is dedicated to the crustacean biologist Victor Vladimirovich Petryashov (19562018). He studied taxonomy and biogeography of mysids and other groups of malacostracan crustaceans, and particularly contributed to the biogeographic division of the cold and moderate waters of the World Ocean, based on the distribution of mysids.

. The subgenus is found in both hemispheres, in the North Atlantic, Indian Ocean and South Pacific, and can probably be considered as bipolar-tropical. However, it has not been yet recorded from the Antarctic.All species have been collected at somewhat shallower localities, from epi- to mesopelagic zones, and have not been found in the bathypelagial.
