Abstract

The type species of Brachytoma Swainson, 1840, Pleurotoma strombiformis Sowerby, 1839 [= P. stromboides Sowerby, 1832] is considered a nomen dubium, its purported type specimen being of unknown origin and status. The genus Brachytoma and the subfamily Brachytominae Thiele, 1929, must thus be rejected as of doubtful application. The genus Ptychobela Thiele, 1925, is referred to the Crassispirinae on radula characters. The earliest available name for its type species, Pleurotoma [= Clavatula] crenularis Lamarck, 1816 (o.d.), is Murex nodulosus Gmelin, 1791, for which a neotype is designated. Pleurotoma crenularis Kiener, 1840 (non Lamarck, 1816) and Brachytoma vexillium Habe & Kosuge, 1966a (= B. vexillum Habe & Kosuge, 1966b) are synonyms of Drillia suturalis Gray, 1838. Pleurotoma sumatrensis Petit de la Saussaye, 1852, is shown to be a valid species, and a lectotype is designated and descriptionbed. Ptychobela opisthochetos sp. n. from Mozambique is descriptionbed. Types figured: Drillia suturalis Gray, 1838, C. griffithii Gray in Griffith & Pidgeon, 1834 (holotypes); Pleurotoma sumatrensis (lectotype); Murex nodulosus (neotype).
