Paraprionospio tamaii Delgado-Blas, 2004: 191 –193, figs 1A–K.

Type locality. Lake Worth, Florida, USA (26º36´N, 80º 03´W), muddy sand, 2.5– 13 m.

Type material. Holotype (LACM-AHF POLY 2139), paratypes (UMML 22.717, 22.718, 22.719, ECOSUR (0049).

Records. Only known from type locality.

Remarks. Yokoyama (2007) synonymized Paraprionospio tamaii and P. yokoyamai Delgado-Blas, 2004, with P. alata (Moore, 1923) from off Point Pinos Lighthouse, Monterey Bay, California, 102 m. However, we do not agree with these synonymies since P. tamaii, P. yokoyamai and P. alata have different notopodial and neuropodial lamellae. These features have been used to separate other members of the genus. Their geographic distributions are remarkably different too: P. tamaii is found on the Atlantic Ocean side of Florida and perhaps northwards, while P. yokoyamai occurs in the Gulf of Mexico towards the south Caribbean. Therefore both species are considered as valid and P. alata, originally described from southern California, is not present in the Grand Caribbean (Delgado- Blas 2009).
