New species in Galeommatoidea (Bivalvia) from Namibia

Four new species in the superfamily Galeommatoidea (Bivalvia) were found in sediment samples from the continental shelf and upper bathyal slope off Namibia, SW Africa: Kurtiella namibiensis n. sp., Bornia walvisensis n. sp., Scacchia aartseni n. sp. and Scacchia huberi n. sp. One live specimen of Bornia walvisensis n. sp. was brooding. A commensal relationship is likely between Bornia walvisensis n. sp. and the decapod host Kraussillichirus kraussi (Stebbing, 1900).
