This work is the continuation of the study of the Pyramidellidae from deep waters in the Central and Tropical South Pacific collected by IRD and MNHN in numerous campaigns over the years. In this work the species belonging to the tribes Eulimellini and Syrnolini have been included. In total 154 species have been studied, 8 of which were previously known (but one with a non valid name), whereas the remaining 146 proved to be new to science. The type material of the already known species is displayed and micrographs to the scanning electron microscope of the material of the new species have been shown. In the tribe Eulimellini, a total of 110 species have been studied; they belong to six genera: Hamarilla, Ebalina, Eulimella, Raoulostraca, Bouchetmella (new genus) and Careliosis. The great majority of species (92) were included in the genus Eulimella. In the tribe Syrnolini, 44 species have been studied, belonging to 6 genera: Iphiana, Syrnola, Puposyrnola, Colsyrnola, Styloptygma and Aghata; most species (35) were included in the genus Syrnola. In the Conclusions and Comments part, information about the number of specimens collected for each species, its geographical distribution and bathymetry area are mentioned. A new name is given to Eulimella angusta (Saurin, 1959) non Watson, 1886. |
