The larval development of Actumnus setifer (de Haan, 1835) (Brachyura: Xanthoidea: Pilumnidae) described from laboratory reared material

Abstract

The complete larval development of Actumnus setifer is documented with three zoeal stages and one megalopa being described. The zoeas differ from the only other known larval description from this speciose genus, A. squamosus, in several carapace and abdominal features. These differences may suggest that the two species are not congeneric. A pilumnid larvae bibliography of 31 species is tabulated.
