Pliocene (Zanclean to Piacenzian): Mediterranean Sea ( Italy, Spain).

Pleistocene: (Gelasian to late Pleistocene): Mediterranean Sea ( Italy).

Present-day: NE Atlantic (incl. Cape Verdes, Canary Islands, Morocco, Mauritania); Mediterranean Sea. ( Malaquias et al. 2003; Landau et al. 2003; Nolf & Verstraeten 2013)

Genus Clelandella Winckworth, 1932

Type species. Trochus clelandi Wood, 1828 [= Clelandella miliaris ( Brocchi, 1814) ], OD (Winckworth 1932: 220). Pliocene, Mediterranean Sea.

Diagnosis. Conical, jujubiniform shells about as high as broad; whorls outline straight. Sculpture comprising beaded spiral cords; periphery of last whorl with peripheral angle, usually with peripheral rim. Umbilicus absent or minute. Aperture strongly prosocline with nacreous surface inside ( Gofas 2005).

Remarks. The genus is distributed in the Mediterranean Sea and NE Atlantic, represented by several insular endemics ( Gofas 2005). The earliest known records come from the late Miocene of the NE Atlantic and the Mediterranean Sea. An early Miocene occurrence from Italy, mentioned by Sacco (1896) needs confirmation.
