Benthonellania agastachys Bouchet & Warén, 1993 (Fig. 8 A-D) MATERIAL EXAMINED. — 84 sh., DW130. REMARK Hernández et al. (2011) reported Benthonellania oligostigma Bouchet & Warén, 1993 from the Canaries, and illustrated a specimen (from the private collection of Winfried Engl, Germany) collected in 330 m depth off Fuerteventura. However B. oligostigma , originally described from off Madeira in 990 m depth, has a much more conical, not cyrtoconoid spire, has about half as many axial ribs as the species found in the Canaries, does not have a thickened outer lip and has a much more blurry spiral sculpture. Conversely, both our specimens and that illustrated by Hernández et al. adjust to Benthonellania agastachys , described from a single juvenile specimen collected in 500 m between Fuerteventura and Cape Juby, Morocco (actually in Moroccan waters but very close to the divide). Benthonellania agastachys was abundant in DW130 and a fully adult shell, with well-developed outer lip, is here figured. : Published as part of Ortega, José Rafael & Gofas, Serge, 2019, The unknown bathyal of the Canaries: new species and new records of deep-sea Mollusca, pp. 513-551 in Zoosystema 41 (26) on page 524, DOI: 10.5252/zoosystema2019v41a26, http://zenodo.org/record/3726028 : {"references": ["BOUCHET P. & WAREN A. 1993. - Revision of the Northeast Atlantic bathyal and abyssal Mesogastropoda.
