Abstract
The neogastropod family Pseudolividae Cossmann, 1901, is a Late Cretac eous to Recent group of about one hundred species characterized by a s piral groove (pseudolivid groove) on the lower half of the last whorl, a labral tooth on the outer lip at the end of this groove, a posterio r notch at the adapical end of the outer lip, spiral sculpture increas ing in prominence toward the base, and an indeterminate, sharp-edged, planar outer lip. A genus-level revision based on shell characters sup ports previous anatomical studies in recognizing the Pseudolividae as a taxon distinct from other neogastropod families. I recognize fourtee n genera in the Pseudolividae: Benthobia Dall, 1889 (Recent, low-latit ude bathyal and abyssal oceans); Fulmentum Fischer, 1884 (Recent, West and South Africa); Fusopsis Ravn, 1939 (Paleocene, Denmark); Fusulcul us Bouchet & Vermeij, 1997 (Recent, New Caledonia); Hubachia Etayo Ser na, 1979 (Paleocene, Colombia); Luizia Douville, 1933 (Early Miocene t o Recent, West Africa); Macron H. & A. Adams, 1853 (Early Miocene to R ecent, warm-temperate North Pacific and Caribbean); Naudoliva Kilburn, 1989 (Recent, southeastern Africa); Pseudoliva Swainson, 1840 (Early Miocene to Recent, West Africa); Sulcobuccinum d'Orbigny, 1850 (Late C retaceous (Campanian) to Early Oligocene, warm seas worldwide); Sulcol iva, new genus (type species: Pseudoliva monilis Olsson, 1928; Eocene, Peru); Testallium Vermeij & DeVries, 1997 (Early Miocene to Late Plio cene, western South America); Triumphis Gray, 1857 (Early Miocene?, Re cent, tropical eastern Pacific); and Zemira H. & A. Adams, 1853 (Late Eocene to Recent, Australia). I designate Buccinum fissuratum Deshayes , 1835, the type species of Sulcobuccinum, of which the following taxa are subjective junior synonyms: Buccinorbis Conrad, 1865; Calorebama Squires, 1989; Pegocomptus Zinsmeister, 1983; and Popenoeum Squires, Z insmeister & Paredes-Mejia, 1989. The genus Sylvanocochlis Melvill, 19 03, is a junior subjective synonym of Fulmentum. Pseudoliva guppyi Man sfield, 1925, from the Late Miocene of Trinidad, is assigned to Fusulc ulus With great hesitation. I propose Sulcobuccinum multinodulosum as a replacement name for Pseudoliva chavani Glibert, 1973, non Tessier, 1952. Macron meleani is a new species described from the Recent fauna of the Gulf of California. Genera removed from Pseudolividae include A ustrosphaera Camacho in Furque & Camacho, 1949 (Late Cretaceous to Pal eocene, Argentina); Seymourosphaera Oleinik & Zinsmeister, 1996 (Early Paleocene, Seymour Island, Antarctic Peninsula); and the Late Cretace ous genera Fulgerca Stephenson, 1941, Hydrotribulus Wade, 1916, and Pt ychosyca Gabb, 1877, all from the Gulf Coastal Plain of the United Sta tes. These taxa are not reassigned to other families, but belong to ba sal buccinoids. Nicema Woodring, 1964, which has sometimes been consid ered a subgenus of Triumphis, is a Late Miocene to Recent tropical Ame rican genus here assigned to the buccinid subfamily Photinae. The Plio cene to Recent South African genus Melapium H. & A. Adams, 1853, may b elong to the largely Paleogene family Strepturidae.
