Remarks.
This species was originally described from
Japan
. The only record of this species from
Australia
is by
Monro (1924)
. In this paper he considered
E. grubei
Gravier, 1900
, described from the Red Sea, a junior synonym of
E. microprion
. Both species were reviewed and considered valid by
Fauchald (1992)
. The
type
of
E. grubei
is incomplete;
E. microprion
was not represented by the
types
, but by other, complete specimens identified by Marenzeller from near the
type
locality (
Fauchald 1992
). The size of the specimens of the two species is similar. The two species resemble each other in that both have dark aciculae and subacicular hooks, branchiae present before chaetiger 10, and articulated antennae, palps and peristomial cirri. The notopodial cirri are articulated in anterior chaetigers in
E. grubei
and throughout the body in
E. microprion
.
The two species can be separated perhaps most easily by the distribution of the branchiae, which are present from chaetiger
3 in
E. grubei
and from chaetiger
7–8 in
E. microprion
and by the shape and distribution of the subacicular hooks. These are single and present from about chaetiger
24 in
E. grubei
and usually double, sometimes triple, and present from about chaetiger
40 in
E. microprion
. No examined material could be identified as
E. microprion
or
E. grubei
.
Thus, we suggest that
E. microprion
does not occur in Australian waters.
