Abstract

Two new species of the little-known scolecitrichid genus Macandrewella are described from southern Japan. Macandrewella chelipes sensu Wilson (1950) from the southern Pacific is also revealed to be new to science. The generic diagnosis is partly emended. Macandrewella seems to be distributed exclusively in the hyperbenthic zone of the tropical/subtropical Indo-Pacific region. A gut content analysis of the two new species from Japan disclosed that Macandrewella is a specialized detritivore, feeding mainly on small crustacean carcasses and/or sloughs, whereas other scolecitrichids are general detritivores. This specialization in feeding may be associated with the presence of a single cephalic lens in species of the genus.
