A new species of Clelandella 
Text Figure 3 : Scatter plot for height (H) and width (W) 
examined specimens of C. miliaris. 
Clelandella artilesi n. sp. is also rather close to 
Jujubinus catenatus Ardovini, 2006 from Sicily, but 
this similar in size species has a more elevated spire 
(with a greater H/W ratio of about 1.50), a slightly 
cyrtoconoidal shape, a transversely elongated flared 
aperture, thinner spiral cords on the base and a 
different coloration with reddish brown cords on a 
light green background. 
The new species may also be compared to 
Clelandella madeirensis Gofas, 2005 (Figs 5-6) from 
Madeira, but this species is slightly greater (height up 
to 8.3 mm for a similar number of whorls), has a 
different ontogeny of the cords (S3 appearing first, S2 
later and 2 tertiary cords appearing and growing to 
reach the same size as the other cords, giving 9 spiral 
cords on the last whorl ol the holotype), lacks the 
axial threads between the spiral cords and has more 
numerous (up to 12 or 13), uneven and thinner spiral 
cords on the base. 
Etymology. After Miguel Artiles, collector from 
Arinaga, South East of the Island of Gran Canaria, 
interested in the marine malacofauna of the entire 
world and occasional collaborator of the third author 
for the study of land shells from Canarias.
