- Cirripedia of MadeiraPublication . Wirtz, Peter; Araujo, Ricardo; Southward, Alan J.We give a list of Cirripedia from Madeira Island and nearby deep water, based on specimens in the collection of the Museu Municipal do Funchal (Historia Natural) (MMF), records mentioned in the literature, and recent collections. Tesseropora atlantica Newman and Ross, 1976 is recorded from Madeira for the first time. The Megabalanus of Madeira is M. azoricus. There are 20 genera containing 27 species, of which 22 occur in depths less than 200 m. Of these shallow water species, eight are wide-ranging oceanic forms that attach to other organisms or to floating objects, leaving just 13 truly benthic shallow water barnacles. This low diversity is probably a consequence of the distance from the continental coasts and the small area of the available habitat. No endemic species have been found.
- First record of the genus Periclimenaeus borradaile, 1815 (decapoda : palaemoniidae : pontoniinae) in the northeastern Atlantic, with the description of a new species, Periclimenaeus auraePublication . Dos Santos, Antonina; Calado, Ricardo; Araujo, RicardoA new species of Periclimenaeus is described from Madeira Island, in the northeastern Atlantic Ocean. It is closest to P. pearsei Holthuis, 1951 from the western Atlantic, but it can be distinguished by the shape of rostrum, the size of exopod in relation to endopod in third maxilliped, the relation between the carpus and the chela of pereiopod 1, the relative size of second pereiopod minor chel a, and the number of setae on appendix masculina. This is the first record of the genus Periclimenaeus in the eastern Atlantic.
