Description
Summary:Alvania sp. (Figs 19 I–K) Material examined. Canary Islands?: Imprecise data, 1 sh (Monterosato coll. ex Mac Andrew, MCZR-M-30074). Remarks. The single shell examined (Fig. 19 I–K) was in the same lot with several shells of A. canariensis , a species ranging from Canary Islands to Selvagens and Madera. We can, therefore, only guess an origin from Canary Islands (considering that Mac Andrew studied particulary that fauna). The shell is similar to A. pizzinii n. sp. in the angled outline and the wide subsutural ramp devoid of spiral sculpture. It differs by the semitransparent whitish colouration, with small brownish spots on the periphery vs translucent yellowish with large quadrangular subsutural brownish blotches (or monochrome yellowish-orangeish or brownish) in A. pizzinii . It also resembles A. suroiti Gofas (2007), a deep-water species from the Azores (470–480 m depth), which differs in the lack of a distinct microsculpture on both the protoconch and the teleoconch (whereas this shell has distinct spiral sculpture visible on the protoconch). : Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on page 447, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979 : {"references": ["Gofas, S.
