ABSTRACT from "Trichotropidae" by R.Egorov, D.Alexeyev, 1998.
"Species of the family Trichotropidae are mostly distributed in cold and
subtropic waters of both hemispheres. Presently, 26 species from 7 genera
are known for seas of Russia and adjacent regions. Three species are
described as new. A new subgenus, Ovotropis subgen. nov., is isolated in
the genus Iphinoe. The taxonomic position of the genus Trichamanthina is
specified: it has been previously assigned to the family Capulidae
(Golikov, 1986: 12). The character of periostracum, the presence of
operculum, and the structure of radula indicate, in our opinion, that
this monotypic genus belongs to the family Trichotropidae. The highest
species diversity was recorded in the Okhotsk Sea: from Kamchatka to
northern shores of Japan. Most species usually occur at 70 to 250
m; representatives of the family from cold and temperate waters of
northern hemisphere are distrubuted from upper intertidal zone
(Turritropis insignis) to the depth of 944 m (Ariadnaria borealis, after
Golikov, 1986: 22).
As a result of studying rich collections stored in the
Zoological Institute of Russian Academy of Sciences
(St.-Petersburg), Zoological Museum of Moscow State University
and Institute of Oceanology of Russian Academy of Sciences
(Moscow), as well as private collections (a total of about 1800 specimens),
and based on analysis of literature, we supplemented data on
ecology and distribution of trichotropids, and specified diagnoses of
genera and some rare species. An analysis of original description and
examination of type material allowed to revise the taxonomic position of
some species and their synonymy."
