Overview

Abstract

  • A study of the type material of Antarctic species of conoideans described by Herman Strebel revealed that four species, all originally described in the genus Bela Gray, 1847 (Mangeliidae), are referable to the superfamily Buccinoidea based on radular morphology. Three of the species: B. fluvi cans, B. minor, and B. anderssoni are transferred to the genus Falsimohnia, which is here reviewed. The new buccinoidean genus Strebela is proposed for the species originally described as Bela notophila. Of the five species of the conthologically similar genus Pareuthria Strebel, 1905 that have been recorded within the Antarctic Convergence, two, Pareuthria innocens (Smith, 1907) and P. hoshiaii Numanami, 1996, are transferred to the genus Falsimohnia based on radular morphology. The appropriate generic allocation of Pareuthria plicata Thiele, 1912 is not yet clear; however, major differences in radular morphology exclude it from the genus Pareuthria. The taxa Pareuthria valdiviae (Thiele, 1925) and Pareuthria turriformis Egorova, 1982 are presently known only from their shell morphology. We suggest that they will be referred to other genera when anatomical material becomes available, and that the genus Pareuthria will be limited to the Magellanic region.
