Pseudomurex meyendorffi var. caprensis Bellini, 1929a: 38

Type locality: Capri Island (Naples, Tyrrhenian Sea, Italy) .

Original description: “la forma di Capri, non rara a profondità, è corta, rigonfia e differisce da quella non solo tipica, ma di altre località mediterranee” [the variety from Capri—of Coralliophila meyendorffii (Calcara, 1845) , reported as Pseudomurex meyendorffi Calcara —, not rare at depths, is short and swollen, and differs from both the typical shells and the ones from other Mediterranean localities].

Remarks: having been instituted as a geographic race, we rank it subspecific, and thus available ( ICZN 2012: Art. 10, glossary). Listed as a simple variety or a synonym of Coralliophila meyendorffii (Calcara, 1845) by several authors ( Sabelli et al. 1992; Fasulo 2012), despite no figures ever being published by Bellini (1929a). Spano et al. (2002) listed it as a valid species, “ C [oralliophila] caprensis ”, but with no further comment or description. The original description may easily fit other Mediterranean taxa than C. meyendorffii , the closer ones being Coralliophila brevis (Blainville, 1832) and Coralliophila panormitana (Monterosato, 1869) due to original description and declared depth. Thus, it is considered a nomen dubium ( ICZN 2012: glossary).
