On the distribution and taxonomic limits of Lumbricillus pagenstecheri (Oligochaeta, Enchytraeidae).

- Abstract
Lumbricillus pagenstecheri (Ratzel, 1869) is the most widely distributed and euryhaline representative of a large, mostly littoral, group of Lumbricillus spp. with distinct glandular cover on the ectal spermathecal duct, and a rosette of glands at its ectal end. It is the only species in this group that has been recorded from the shores of both the Atlantic and Pacific oceans and from soil. A freshwater, maybe landlocked, population lives in Lake Kuril'skoe (Far East). It is not identical with L. kamtschatkanus Michaelsen (1929), which was previously reported from the same lake. Lumbricillus pagenstecheri as currently recognized is morphologically different from the rich assemblage of related species from marine littoral of the North Pacific while no clear differences are found between its own marine and freshwater populations.
