The purpose of this application, under Article 23.9.5 of the Code, is to conserve the specific name Pleurotoma scabriuscula Brugnone, 1862 (currently Mangelia scabriuscula, conidae) originally published as Pleurotoma scabriusculum, a junior primary homonym of Pleurotoma scabriuscula Edwards, 1861 (currently Crassispira scabriuscula, turridae). Both names are in use, even though the latter is infrequently reported in the literature, and they have not been considered congeneric since 1899 and are unlikely ever to be treated as congeneric again. We propose that the name Pleurotoma scabriuscula Brugnone, 1862 (which does not have junior synonyms) be conserved by ruling that it is not invalid by reason of being a junior primary homonym.
