Remarks
. 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.
