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."
