ABSTRACT
Two poorly known species of genus Raphitoma Bellardi, 1847 (Gastropoda Conoidea) are
revised. 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.

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

Cordieria pumila Appolloni et al., 2018: 66
ORIGINAL DIAGNOSIS. 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. Saint-Raphaël, port du Poussaï, Le Dramont, 1 sh (LAF).

DESCRIPTION. In square brackets the data of the
holotype. Shell biconic squat, of medium size for
the genus, height: 9–17 mm, mean: 13.9, SD: 2.41
[14]; width: 5–8.6 mm, mean: 6.9, SD: 1.12 [6.3];
H/W: 1.91–2.22, mean: 2.02, SD: 0.11 [2.22].
Protoconch multispiral, rust brown in colour, of
2.75 convex whorls, height 483 µm, width 460 µm,
protoconch I of 1.1 whorls, covered by thin cancellations, protoconch II with a diagonally cancellated
sculpture starting after a zone under the suture with
fine axial threads. The last whorl shows a keel before the onset of the teleoconch. Protoconch-teleoconch boundary slightly flexuose, opisthocline.
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. This quite rare species seems to
occur only in the Western and Central Mediterranean.
COMPARATIVE NOTES. This species is quite similar to one of the morphotypes of R. echinata (Brocchi, 1814) (Figs. 8–10) but differs having a lower

A revision of the Mediterranean Raphitomidae 8: on two less well-know species, R. pumila and R. hispidella n. nov.
DESCRIPTION. In square brackets the data of the
lectotype. Shell fusiform, of medium size for the
genus, height 7–16.5 [10] mm, mean: 10.8, DS:
2.98 [10]; width 3.3–6.6 mm, mean: 4.76, DS: 1.17
[4.4]; H/W 2.12–2.47, mean 2.25, DS: 0.11 [2.27].
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. Spiral
sculpture of 5–6 mean [5] cordlets thinner than the
axial ribs, above the aperture. Cancellation rectangular, with strong and sligthly acute spines at the
intersection of axials and spirals. Subsutural ramp
wide, inclined and slightly arched. Columella simple, “s” slightly sinuous or almost straight anteriorly, angled posteriorly. 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.
