The present material closely resembles the type material of M. mullawa , except subacicular hooks occur from chaetigers 26−36, which is just outside the range of 37−45 given by Hutchings & Karageorgopolous (2003) for the type material. However, the early appearance of the hooks is accountable by the smaller size of the present specimens ( 2.8−3.5 mm wide). As none of the specimens are posteriorly complete we were unable to determine the types of pectinate chaetae in far posterior chaetigers; however, in the material at hand, pectinate chaetae in mid-posterior chaetigers had about 22 teeth—the coarse-tooth types were not observed. The most complete specimen with about 250 chaetigers lacks entirely any limbate capillaries in the subacicular bundle. Marphysa mullawa belongs to the Sanguinea-group of species, which lack limbate capillaries in the subacicular bundle. Apart from M. sanguinea the group also includes M. orientalis Treadwell, 1936 from Amoy, China and M. elityeni Lewis & Karageorgopolous, 2008 from South Africa . Another species that may belong to this group is M. tamurai Okuda, 1934 , but information on the presence or absence of limbate capillaries in this species is lacking. Habitat. Intertidal to 10 m ; muddy sediments and amongst invertebrate fouling communities in protected coastal embayments including harbours and estuaries. Distribution . Northern Australia from Kimberley, Western Australia in the west to Moreton Bay, Queensland in the east.
