Pliocene: Netherlands , France , Sicily ( Pouyet & Moissette 1992 ), Algeria (Haddadi-Hamdane 1996), Tunisia ( Buge 1956 ). Pleistocene:Rhodes ( Moissette & Spjeldnaes 1995 ). This fossil species has mostly been recorded from the Mediterranean and Paratethys basins. It has been recovered in a few instances together with deep-water bryozoan faunas: Messinian of western Algeria ( Moissette 2000 ) and Pleistocene of Rhodes ( Moissette & Spjeldnaes 1995 ). DESCRIPTION Vinculariiform colony. Dichotomous branches mostly flattened. Frontal smooth, zoecial tubes indistinct, quincuncially arranged and isolated, with well-developed sub-circular peristomes. Dorsal slightly convex, with thin transversal growth lines and perforated by small pseudopores.Gonozooid enlarged, also perforated by small pseudopores, occupying the whole width of a branch and encompassing up to ten zoecial tubes. Ooeciostome with flared, transverse and convoluted rim.
