Revision of the genus Goodallia (Bivalvia: Astartidae) with the description of two new species

Abstract

A revision of the Recent species of the genus Goodallia (Astartidae) is presented. Adult shell and prodissoconch morphology of all the species are described and figured. In total, five species are recognized: G. triangularis (Montagu, 1803), G. pusilla (Forbes, 1844), G. macandrewi (Smith, 1881), G. micalii new species, and G. gofasi new species. G. triangularis and G. pusilla are widespread distributed in the Atlantic coasts of Europe and North Africa, and in the Mediterranean. G. macandrewi is restricted to the type locality in the Canary Islands, while what has been called G. macandrewi from the Mediterranean corresponds to an undescribed species here named G. micalii, distributed in the Central and Eastern Mediterranean. A second undescribed species from off the Atlantic Moroccan coast is named G. gofasi, and is known only from the type material of station B33 of the expedition CINECA CHARCOT III. The named forms, variability and distribution of G. triangularis are discussed.
