Leucozonia and related genera of fasciolariid gastropods: Shell-based taxonomy and relationships

Abstract On the basis of shell characters, we review the eight Recent and two fossil species of the fasciolariid neogastropod genus Leucozonia Gray, 1847. These are L. nassa (Gmelin, 1791), type species, from the tropical western Atlantic, a geographically variable species; L. cerata (Wood, 1828) from the tropical eastern Pacific; L. leucozonalis (Lamarck, 1822) from the western Caribbean; L. ocellata (Gmelin, 1791) from the western Atlantic; L. ponderosa Vermeij and Snyder, 1998, from Ilha Trindade, Brazil; L. rudis (Reeve, 1847) from the eastern Pacific; L. triserialis (Lamarck, 1822) from the Cape Verde Islands in the eastern Atlantic; L. tuberculata (Broderip, 1833) from the Galapagos and Cocos Islands in the eastern Pacific; L. rhomboidea (Gabb, 1873) from the Gurabo Formation (early Pliocene) of the Dominican Republic; and L. striatula Vermeij, 1997, from the Cercado (late Miocene) and basal Gurabo Formations of the Dominican Republic. We review species named as or assigned to Leucozonia. The new genus Psammostoma (type species: Mazzalina costata Dall, 1890, early Miocene, Florida) may be related to the ancestry of Leucozonia. In shell characters, Leucozonia appears to be most closely related to the Indo-West Pacific genera Latirolagena Harris, 1897, and Latirus Montfort, 1810, in the latters narrow sense. These three genera, together with Psammostoma and several others, have in common the unusual trait of beaded or discontinuous spiral ridges (lirae) on the adaxial side of the shells outer lip. On biogeographic grounds we argue that beaded lirae evolved at least twice in the Fasciolariidae. The labral tooth of L. nassa and six other species of Leucozonia is a derived feature within the genus and evolved independently of that in three other fasciolariid groups: Benimakia Habe, 1958; Dennantia Tate, 1888; and Opeatostoma Berry, 1958. Genus novum: Psammostoma Vermeij & Snyder.

The fasciolariid gastropod genus Benimakia: New species and a discussion of Indo-Pacific genera in Brazil

Abstract Benimakia Habe, 1958, is a distinctive genus of Fasciolariidae. Its type species, the Indo-West Pacific Recent B. rhodostoma (Dunker, 1860), is distinct from Turbinella fastigium Reeve, 1847, which is here also assigned to Benimakia and with which B. rhodostoma was often confused. We describe B. delicata n. sp. from Samoa and tentatively assign the Brazilian Latirus ogum Petuch, 1979 to Benimakia. At least two Indo-Pacific genera of gastropods besides Benimakia (Caducifer and Quimalea) also contain isolated Brazilian species. How and when these genera reached Brazil, and why many Indo-Pacific genera that have invaded the eastern Pacific do not occur in Brazil, remain unanswered questions. Species nova: Benimakia delicata.

Tapparone-Canefri's Type Material of Fasciolariid Gastropoda (Mollusca) at the Genoa Natural History Museum

ABSTRACT. Types of species nominally belonging to the family Fasciolariidae (Mollusca: Gastropoda) described by C. M. Tapparone-Canefri and housed in the Museo Civico di Storia Naturale in Genoa, Italy are examined and figured. Of nine type lots represented, six represent fasciolariids, two are buccinids and one is a muricid. Lectotypes are selected for Fusus bruijnii Tapparone-Canefri, 1876, Latirus carotianus Tapparone-Canefri, 1880, Peristernia castanoleuca Tapparone-Canefri, 1879, Latirus concinnus Tapparone-Canefri, 1880, Latirus forskalii Tapparone-Canefri, 1875, Latirus scabrosus var. nigritellus Tapparone-Canefri, 1882, Peristernia elegans var. papuensis Tapparone-Canefri, 1879 and Latirus fischerianus Tapparone-Canefri, 1882.

A new genus and nine new species in the Fasciolariidae (Gastropoda: Buccinoidea) from southern California and western Mexico

ABSTRACT. Some fasciolariid species of the eastern Pacific Ocean from western Mexico to Alaska are discussed, with the description of the new genus Araiofusus gen. nov. and nine new species: Fusinus edjanssi sp. nov. from Cedros Island, Pacific coast of Baja California to San Hipolito Point, Pacific coast of Baja California Sur, Mexico; Fusinus laticlavius sp. nov. from deep water off Danzante Island, western Gulf of California, Baja California Sur, Mexico; Fusinus seriatus sp. nov. from the Pacific coast of Baja California Sur, Mexico; Fusinus euekes sp. nov. from the eastern Gulf of California, Mexico; Araiofusus araios sp. nov. from deep water in Monterey Bay to the Gorda Bank off Cabo San Luca, Mexico; Araiofusus eueides sp. nov. from Monterey Bay to Orange County and Catalina Island, south to Cedros Island, Pacific Baja California, Mexico; Harfordia chucksnelli sp. nov. from the Channel Islands and off Santa Barbara; Harfordia mcleani sp. nov. from Monterey County throughout the Channel Islands and south to Cedros Island and Barbarofusus guadalupensis sp. nov. from Guadalupe Island, Pacific Baja California, Mexico. A new name, Hesperaptyxis meridionalis, is proposed to replace the homonymous name Latirus melvilli Dall and Ochsner 1928 non Schepman, 1911, a Pliocene species from the Galapagos Islands. A lectotype is selected for the Recent species Fusus luteopictus Dall, 1877, and a neotype for the Pleistocene species Fusus barbarensis Trask 1855, the type species of Barbarofusus. Types of the previously-named species here assigned to Araiofusus, Harfordia and Barbarofusus are illustrated. Four new combinations are introduced: Araiofusus colpoicus (Dall, 1915), Harfordia arnoldi (Cossmann, 1903), H. robusta (Trask, 1855) and Barbarofusus kobelti (Dall, 1877). Most of the smaller fusinine species from this area not dealt with here were assigned to the genus Hesperaptyxis in a previous paper (Snyder and Vermeij, 2016).

Fasciolaria guyanensis, a new species of Fasciolariidae (Gastropoda: Neogastropoda) from northeastern South America

ABSTRACT. Fasciolaria guyanensis n. sp. is described and differentiated from its nearest congeners F. hollisteri Weisbord, 1962 and F. tulipa Linnaeus, 1758 and from other congeners by its enlarged protoconch lacking axial riblets. The new species is known from Guyana, Suriname, Guyane and northeastern Brazil. A lectotype is designated for F. tulipa concolor Kobelt, 1876, which is considered a junior subjective synonym of F. tulipa.

Species named in Fasciolariidae by Tapparone-Canefri and their types (Mollusca: Gastropoda)

ABSTRACT. In a previous paper (Snyder and Callomon, 2010) the types of the fasciolariid species described by C. M. Tapparone-Canefri and held in the Museo Civico di Storia Naturale in Genoa, Italy were examined and figured. Here we review the material held in the Museo Zoologico de “La Specola” at the Universita degli Studi in Firenze (Florence), Italy, and select lectotypes. Peristernia kobeltiana Tapparone-Canefri, 1879 is here transferred to Benimakia and maintained as a junior synonym of Benimakia rubens (Lamarck, 1822) comb. nov. Fusus xantochrous Tapparone-Canefri, 1880 is here transferred to Latirus.

Rediscovery and redescription of Latirus vexillulum (Reeve, 1842) (Gastropoda: Fasciolariidae: Peristerniinae)

ABSTRACT. Latirus vexillulum (Reeve, 1842), described without locality, is redescribed and reported from Caroline Island in the Southern Line Islands, Kiribati, central Pacific. Specimens of L. vexillulum found at the Academy of Natural Sciences of Drexel University and previously reported as L. amplustre (Dillwyn, 1817) are here distinguished from that species.

The Recent Species of Granolaria (Gastropoda: Fasciolariidae), with Clarification of the Identity of Murex salmo Wood, 1828

ABSTRACT. Murex salmo Wood, 1828 and Fasciolaria granosa Broderip, 1832 are shown to be conspecific. The first available name for a different species often identified as Pleuroploca or Fasciolaria salmo is Fasciolaria valenciennesii Kiener, 1840, which Deshayes (1843) incorrectly treated as a synonym of P. salmo. In the last several decades, authors who presumably intended to use the name Pleuroploca salmo sensu Deshayes have inadvertently illustrated true P. salmo. Since usage of the names is not consistent, we follow strict priority and synonymize Fasciolaria granosa with Murex salmo. The currently valid names for these species are Granolaria salmo (Wood, 1828) and Granolaria valenciennesii (Kiener, 1840).

On Some Fusinus from the East and South China Seas (Mollusca: Gastropoda: Fasciolariidae), with Description of a New Species

ABSTRACT. Four species in the fasciolariid genus Fusinus obtained by Chinese commercial fishing boats are identified and compared with material from the Philippines and Japan. One is here described as new to science, Fusinus marisinicus n. sp. Phenotypic variation in Fusinus salisburyi, F. forceps and F. diandraensis is discussed, and various forms are figured with their intergrades. Further descriptive details of F. diandraensis are given, and new comparisons are made with sympatric congeners including F. perplexus and F. flavicomus. New taxon: Fusinus marisinicus Callomon and Snyder
