Abstract
ABSTRACT. The geographical distribution of Bathoxiphus ensiculus (Jeffreys, 1877) and Cadulus platensis Henderson, 1920 is greatly extended based on new records, the former being registered for the first time in the southwestern Atlantic. The type materials of both species are figured and an updated diagnosis of Bathoxiphus Pilsbry & Sharp, 1897 is presented. A new deep-sea species of Cadulus is described, Cadulus victori sp. nov., known from only empty shells collected in the Northeast Brazil (off Alagoas and Bahia states) and distinguished from his congeners mainly by the strongly inflated shell, general outline and dimensions. The present study reinforces that although recent taxonomic revisions have been performed on the Scaphopoda from the southwestern Atlantic, there are still unknown or unrecorded species in museum collections, mostly from poorly sampled areas, especially in the deep sea.

The geographical distribution of Bathoxiphus ensiculus (Jeffreys, 1877) and Cadulus platensis Henderson, 1920 is greatly extended based on new records, the former being registered for the first time in the southwestern Atlantic
The present study reinforces that recent taxonomic revisions have been performed on the Scaphopoda from the southwestern Atlantic, there are still unknown or unrecorded species in museum collections, mostly from poorly sampled areas, especially in the deep sea
In the present study we report new occurrences of Cadulus platensis Henderson, 1920 and Bathoxiphus ensiculus (Jeffreys, 1877), and describe a new species of Cadulus Philippi, 1844
Summary
The material examined is housed in different malacological collections and consists exclusively of empty shells. Most samples from Brazil were collected by two different projects: 1) MARSEAL: “Caracterização Ambiental da Bacia de Sergipe-Alagoas” [Environmental Characterization of Sergipe and Alagoas Basin], between 5 and 4300 m, coordinated by PETROBRAS/CENPES; 2) “Crostas Cobaltíferas da Elevação do Rio Grande”. The number inside the brackets in the examined material indicates the number of shells present in each lot. Ratios based on previous measurements were calculated following Caetano et al (2010): L/Max; Hd/Wd; Hv/Wv. Institutional abbreviations used : MCZ: Museum of Comparative Zoology, Harvard University, Cambridge, Massachussetts, USA; MNHN-IM: Muséum national d’Histoire naturelle, Paris, France; MNRJ: Museu Nacional, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil; NHMUK: Natural History Museum of the United Kingdom, London, England, United Kingdom; USNM: Smithsonian Institution’s National Museum of Natural History, Washington DC, USA; CZUFS SCA: Universidade Federal de Sergipe, São Cristóvão, Sergipe, Brazil. Due to the fire in the “Museu Nacional” (Zamudio et al, 2018), some vouchers housed or on loan at this collection were destroyed and are here indicated with a dagger (†) aside the catalog number
