Laomedea pseudodichotoma Vervoort, 1959 (Hydrozoa, Campanulariidae) and Stegopoma bathyale Vervoort, 1966 (Hydrozoa, Tiarannidae), two new records from the Bay of Biscay

Abstract

Two thecatae hydrozoan species, Laomedea pseudodichotoma (Campanulariidae) and Stegopoma bathyale (Tiarannidae) previously known from the west African coast and several south Iberian localities (Cadiz, Cape Sao Vicente), are recorded for the first time in the Bay of Biscay. Observations were made on material collected from three stations (depth range 172-893 m) located along the Central Cantabrian coast off Asturias (southern Bay of Biscay). The recording of these species in the Bay of Biscay waters shows that their distribution extends further to the north in the temperate Atlantic than previously known.
