In past, sometimes treated as conspecific with P. cahow, but molecular studies indicate that the two are separate species#R#R. Commonly considered conspecific with P. caribbaea (which see). May divide into two taxa, possibly at species level, given differences in morphology, timing of records at sea, and genetics#R#R. Monotypic.

Distribution:

Caribbean Sea and W Atlantic Ocean, breeding in Hispaniola (SW & SE Haiti and SW Dominican Republic, from Massif de la Hotte and Massif de La Selle E to W end of Sierra de Bahoruco)#R, on Dominica and possibly in SE Cuba (Sierra Maestra)#R. May have nested in Martinique and formerly bred commonly in Guadeloupe, where now believed extinct.
