Guadaloupe ( Gillet 1987, Amoureux 1985). Trinidad and Tobago: Oropuche ( Gobin 1990).   Remarks.This species is easily distinguished by having five pairs of branchiae, three of which have digitiform pinnules, and by the extremely large posterior pair of prostomial eyes. Foster (1971a)proposed the synonymy of  Prionospio heterobranchia texana Hartman, 1951, and P. h. newportensis Reish, 1959, with  P. heterobranchia,and this was followed by Maciolek (1985). The record of  P. heterobranchiain the Grand Caribbean is questionable, requiring comparison with the typematerial.
