TI  Review of the species if the genus Micronephthys (Polychaeta:
Nephthyidae) from the White Sea.
SO  Zool. Zh., 75, 6:831-840 (in Russian, with English summary).
AB The examination of numerous specimens of Micronephthys spp. from the
White Sea shows, that M.neotena (Noyes, 1980) is present besides M.minuta
Theel, 1879 in the material. The species can be easily distinguished under
binocular both in living and preserved condition. In M.minuta branchiae
usually start from 7th-8th segments, pharynx with 20, more seldom 18
regular rows of subterminal papillae. In M. neotenus branchiae usually
start from 6th segment; there are 20 subterminal papillae distally, i.e.
originally there are 20 rows as well, but proximally part of rows joined
and in the middle part of pharynx always there are 16 rows only. Both
species are re-described (no complete and correct description of M.minuta
exists until now). Besides the morphological difference they occupy
separate niches (live at different depths and temperatures, have different
spawning time). The complete review of literature data on biology and
distribution is given.
