Abstract: Eleven genera of Borsoniinae occur in southern Africa and Mozambique. Of these, one genus (Tropidoturris, type-species Pleurotoma scitecostata Sowerby, 1903) is new; another (Mitrel/atoma Powell, 1942) is the first non-fossil record, and Maorimorpha Powell, 1939, is recorded outside New Zealand for the first time. Maoritomella Powell, 1942, and Pulsarella Laseron, 19S4, are treated as full genera. Helenella Casey, 1904, Apaturris Iredale, 1917, and Cymakra Gardner, 1937, are synonyms of Mitrolumna Bucquoy, Dautzenberg & Dollfus, 1883, which is regarded as a subgenus of Mitromorpha Carpenter, 1865. 45 species are reported; of these, 24 species and two subspecies are new, viz. Bathytoma (ParabathYlOma) prodicia, B. (Micantapex) arbucklei; Tropidoturris anaglypta, T. fossata notialis, T. planilirata, T. simplicicingula pondo; Tomopleura oscitans; Maoritomella tarrhion, M. granilirata, M. c/upeispina, M. densecostulata, M. megalacme, M. leptopleura; Microdrillia dinos; Mitrel/atoma milra; Mitromorpha (Mitrolumna) kennel/yi, M.(M) chelonion, M.(M.) brevispira, M.(M.) iridescens, M (M.) rotundicostata, M. (M.) tenuilirata, M. (M.) nodilirata, M. (M.) ustulata, M. (M.) maraisi, M (M) amphibolos, M (M.) platacme. New combinations: Cominella? sulcata Sowerby, 1892, is a Maorimorpha; Pleurotoma fultoni Sowerby, 1888, and Oligotoma clevei Jousseaume, 1883, belong to Pulsarella Laseron, 1954; Be/a eva Thiele, 1925, and Drillia pleonastica Barnard, 1958, are Maoritomella; Acrobela acus Barnard, 1958, belongs to genus Teretia Norman, 1888 (subfamily Raphitominae); Mitromorpha veneris Barnard, 1964, belongs to Charitodoron Tomlin, 1932 (family Mitridae). New records: Tomopleura nivea (Philippi, 1851), Microdrillia patricia (Melvill, 1904), M. circumver tens (Melvill & Standen, 1901).

TL;DR: Seven Mediterranean species of the genus Mitromorpha Carpenter, 1865 as currently conceived, are here described as new, all included conservatively in the subgenus Mitrolumna Bucquoy, Dautzenberg & Dollfus, 1883.
Abstract: The Mediterranean species of the genus Mitromorpha Carpenter, 1865 as currently conceived, are herein reviewed. The genus is represented in the Mediterranean Sea by eleven species, of which seven are here described as new, all included conservatively in the subgenus Mitrolumna Bucquoy, Dautzenberg & Dollfus, 1883: Mitromorpha (Mitrolumna) columbellaria (Scacchi, 1836), Mitromorpha (Mitrolumna) olivoidea (Cantraine, 1835), Mitromorpha (Mitrolumna) karpathoensis (Nordsieck, 1969), Mitromorpha (Mitrolumna) wilhelminae (van Aartsen, Menkhorst & Gittenberger, 1984), Mitromorpha (Mitrolumna) alyssae n. sp., Mitromorpha (Mitrolumna) bogii n. sp., Mitromorpha (Mitrolumna) cossyrae n. sp., Mitromorpha (Mitrolumna) nofronii n. sp., Mitromorpha (Mitrolumna) mariottinii n. sp., Mitromorpha (Mitrolumna) mifsudi n. sp., and Mitromorpha (Mitrolumna) tricolorata n. sp. Neotypes are designated for: Mitra columbellaria Scacchi, 1836, [currently Mitromorpha columbellaria (Scacchi, 1836) comb. nov.], and Mitrolumna algeriana Pallary, 1900 ex Monterosato ms. [currently Mitromorpha algeriana (Pallary, 1900) comb. nov.] considered as a synonym of Mitromorpha columbellaria (Scacchi, 1836). The latter is the oldest available name for the most common and widespread Mediterranean species of Mitromorpha. A lectotype is selected for Mitra leontocroma Brusina, 1866 [currently Mitromorpha leontocroma (Brusina, 1866) comb. nov.], previously considered as a junior synonym of Mitromorpha olivoidea (Cantraine, 1835) but here considered as a junior synonym of Mitromorpha columbellaria (Scacchi, 1836). Mitromorpha melitensis (Mifsud, 1993) is a synonym of Mitromorpha olivoidea (Cantraine, 1835). Mitromorpha mediterranea Mifsud, 2001 is a synonym of Mitromorpha columbellaria (Scacchi, 1836).
TL;DR: A new species of Conidae is described from Brazilian waters, with two unnamed Brazilian species being diagnosed as possessing strong axial ribs, second spiral cord on the body whorl more pronounced and yellowish-brown spiral bands.
Abstract: A new species of Conidae is described from Brazilian waters. Mitromorpha santosi sp. nov. from the Continental Slope off the state of Rio Grande do Norte (north-east Brazil: 04°50'60"-04°51'40"s 35°06'01"-35° 06'46"W) is compared with M. biplicata (western Atlantic), M. usta (eastern Atlantic), M. dalli (north-eastern Atlantic), M. popeae (West Indies), M. undulate (West Indies) and two unnamed Brazilian species being diagnosed as possessing strong axial ribs, second spiral cord on the body whorl more pronounced and yellowish-brown spiral bands. In addition, a lectotype for Mitromorpha undulata, is designated herein.
TL;DR: The species belongs to the Columbellidae; however, it is different from all existing genera, and a new taxon is erected for the species, Minipyrene.
Abstract: Columbella dormitor Sowerby, 1844, was placed by the malacologists in the genera Columbella, Pyrene, Parametaria (all Columbellidae), and in Mitromorpha (Turridae). It is a rare species, living in deeper water in the southern Caribbean. The species belongs to the Columbellidae; however, it is different from all existing genera. A new taxon is erected for the species, Minipyrene.
