Abstract(s)

Descreve-se brevemente a ocorrência das seguintes espécies de invertebrados marinhos das águas açoreanas: os moluscos Pleurobranchus testudinarius, Aplysia fasciata, Diaphorodoris luteocincta, Discodoris atromaculata, Platydoris argo, Polycera elegans, Tambja ceutae, os crustáceos Lysmata nilita, Eualus occultus, Aristaeomorpha foliacea, Aristeus antennatus, Cycloes cristata, Pilumnus hirtellus, Polybius henslowii, o foronídeo Phoronis cf. hippocrepia, o equinoderme Brissus unicolor, sendo todos novos registos para a Região. Fizeram-se também algumas observações sobre: o bivalve Pteria hirundo, os crustáceos Plesiopenaeus edwardsianus, Liocarcinus marmoreus, Plagusia depressa, Inachus phalangium, Albunea carabus, o equinoderme Centrostephanus longispinis e o tunicado Clavelina lepadiformis. Os 16 novos registos confirmam o conceito bem estabelecido de a fauna e flora litoral dos Açores terem "características Mediterrâneas".

ABSTRACT: We briefly comment on the occurrence of the following marine invertebrate species in Azorean waters: the molluscs Pleurobranchus testudinarius, Aplysia fasciata, Diaphorodoris luteocincta, Discodoris atromaculata, Platydoris argo, Polycera elegans, Tambja ceutae, the crustaceans Lysmata nilita, Eualus occultus, Aristaeomorpha foliacea, Aristeus antennatus, Cycloes cristata, Pilumnus hirtellus, Polybius henslowii, the phoronid Phoronis cf. hippocrepia, the echinoderm Brissus unicolor are all new records. Some notes are also made on the bivalve Pteria hirundo, the crustaceans Plesiopenaeus edwardsianus, Liocarcinus marmoreus, Plagusia depressa, Inachus phalangium, Albunea carabus, the echinoderm Centrostephanus longispinis, and the tunicate Clavelina lepadiformis. The 16 new records confirm the well established concept of the "Mediterranean character" of the littoral fauna and flora of the Azores.
