Raphitoma pumila (Monterosato, 1890) is redescribed and Cordieria cordieri var. hispida, Monterosato, 1890 is raised to species level and transferred to the genus Raphitoma, hence requiring the creation of a replacement name (R. hispidella nomen novum) due to secondary homonymy with R. hispida Bellardi, 1877. KEY WORDS Raphitomidae; revision; taxonomy; nomen novum. Received 10.01.2019; accepted 13.03.2019; published online 30.03.2019 INTRODUCTION The Raphitomidae are currently considered as a well-supported clade of the Conoidea (Bouchet et al., 2011), worthy of family ranking. It is probably the most diverse family of Conoidea, in terms of species richness, ecological range and anatomical disparity (Kantor & Taylor, 2002), and are therefore considered as potentially ideal candidates for toxin discovery (Puillandre et al., 2017). We are currently revising the Raphitomidae of the Mediterranean Sea and adjacent Atlantic coasts. We provisionally estimated ca. 50 Mediterranean extant species, some of which still undescribed. The taxon Raphitomidae Bellardi, 1875 is based on the genus Raphitoma Bellardi, 1847 which was introduced as comprising 34 fossil and recent species (Bellardi 1847: 85), previously classified in various genera (such as Pleurotoma and Clathurella). During this revision, we have found a quite rare species of Raphitoma described by Monterosato (1890) as a variety of the so called Cordiera reticulata (= Raphitoma echinata). In our opinion it is a good species having its own peculiar characteristics MATERIAL AND METHODS Our approach was exclusively based on shell morphology due to the almost total lack of anatomical data. Specimens studied come from private collections (see Abbreviations). Light photographs were taken (if not otherwise stated) by Stefano Bartolini using a Canon EOS 400D digital photocamera, with standard objective 50 mm + adapted lens (25 and 12.5 mm) for 16 58 RICCARDO GIANNUZZI-SAVELLI and 8 mm vintage cine camera and by Yves Lafontaine.

Monterosato (1890): “Cordieria reticulata var. pumila Monts. - Più corta; si direbbe una forma nana, spesso incolore, reticolazione più fitta, bocca fortemente dentata - Funnazzi, Algeria, Lipari etc.” (shorter; it would seem a dwarf form, often colorless, denser cross-linking, strongly toothed mouth - Funnazzi, Algeria, Lipari etc.) TYPE MATERIAL. MCZR-M 16774: Lectotype from Algeria (14 x 6.3 mm, labelled “tipo”) and paralectotypes from Palermo (16.7 x 7.8 mm and 14.3 x 7.5 mm). According the ICZN art. 72.4.7 the term “tipo” of the labels is not necessarily an evidence that this specimen is the “holotype”. However we respect the indication of Monterosato and fix this specimen as a lectotype. TYPE LOCALITY. Algeria. ExAMINED MATERIAL. The type material and: France.

Teleoconch of 5.5–7.5 [6.5] rounded whorls, stout, suture incised, sculpture robust. Densely disseminated microgranules in the surface. Axial sculpture of 14–18 [16] orthocline (occasionally slightly opisthocline or prosocline), equidistant ribs, and interspaces larger than the ribs in the last whorl, narrower in the others. Spiral sculpture above the aperture of 5 to 6 [6] cordlets. Sometime 1 or 2 supplementary small cordlets can occur. Cancellation rectangular, with strong, elongated and acute tubercles at the intersections. Subsutural ramp large, with one or two small spiral cordlets. Columella simple, slightly sinuous anteriorly. Outer lip thick with 9–12 strong inner denticles [12], the 2 most anterior more robust and delimiting the short but wide and conical siphonal canal. Siphonal fasciole with 6–9 [7] nodulose cords with first 3 more strong. Colour uniformly light straw sometime with a pale brownish band around the suture and on the low part of the last whorl. Occasionally comma-shaped white spots on the subsutural ramp. Sometime there are whitish chevron among axial ribs of the last whorl. Soft parts unknown. DISTRIBUTION.

In square brackets the data of the lectotype.

Teleoconch of 5.5–7 [6] convex whorls, fusiform and thin, suture thin, sculpture raised. Scattered microgranules in the surface of part of the first teloconch whorl. Axial sculpture of 11–14, mean: 12, DS: 0.98 [13] orthocline, equidistant ribs, and interspaces three times wider than the ribs.

Siphonal channel long and open that sometime can be twisted. Outer lip thin with 9–12 mean 10 [peristome not complete] weak inner lyrate denticles. Siphonal fasciole with 8–9 cords [8]. Colour variable from uniformly yellow straw in the background (from ligth to dark), up to bright brown. On the last whorl is present a darker subsutural band. Comma-shaped white spots on the darker subsutural ramp. Enterely white specimens are known. The darker specimens are typical in the coralligenous biocenosis. Soft parts unknown. DISTRIBUTION. Mediterranean Sea and atlantic coasts of Portugal, Spain and France in the circalittoral zone. REMARKS. Cordieria cordieri var. hispida Monterosato, 1890 is a valid taxon, which we deem deserving the rank of a species (and is an available name under art. 45.6.4 of the ICZN), although belonging to the genus Raphitoma, hence Raphitoma hispida (Monterosato, 1890) n. comb. The new combination makes the name hispida Monterosato, 1890 a secondary homonym (ICZN art. 59) of R. hispida Bellardi, 1877 (see Bellardi, 1877) so a new name is necessary and we propose hispidella nomen novum, diminutive adjective of the Latin word “hispida”. In the original description Monterosato (1890) compares this “variety” with Cordieria reticulata (= Raphitoma echinata) stating that this has a “revolute apex” (paucispiral). A rather surprising statement because Monterosato (1884: 131) describes it instead with “apice conico, acutissimo, composto 65 di tre giri di spira punteggiati” (conical apex, very acute, composed of three punctuated whorls). We believe this so-called variety is a good species. It differs constantly, without intermediates, by R. cordieri (Payraudeau, 1826) for: always smaller dimensions (max 16.3 vs. 25); very large and arched subsutural ramp vs. large and inclined; different size of protoconch (600 x 509 µm vs. 475 x 350 µm) and different number of whorls (3 vs 2.3); for their yellow straw/witish protoconch vs. milk white; more bristly and scaled profile versus less brittle and regular; shorter and open siphonal channel; lack of supplementary cordlets sometimes present in R. cordieri; rectangular cancellations vs. subquadrate; siphonal fasciole with less strong and closer nodules; siphonal fasciole with 8–9 nodulose cordlets vs. 6–7; thin, lirates and well-spaced teeth vs, lirates, evidents with some cordlets rather strong. Raphitoma hispidella could be confused with some morphs of R. echinata but the last have a shorter siphonal channel, stronger inner denticles and is more robust. Raphitoma horrida (Monterosato, 1884) resemble in some way to R. hispidella but can be easily separated having only 4 cordlets above the aperture, the shorter siphonal channel and more rounded and low aperture.
