Colour.
Carapace and abdominal somites 2–4 pale orange/ pink. Rostrum red, supraocular spines white or red and white on distal half. P1 pale orange/pink with white fingers, P2–4 pale orange on meri and carpi, white on propodi, dactyli white with red tips.
Genetic data.
COI and 16S; see
Table 1
.
Remarks.
Munida compacta
is very close to
M. rubridigitalis
Baba, 1994
, and
M. julumunyju
sp. nov.
from eastern and western Australia, respectively, and
M. rhodonia
, from
New Caledonia
. These species can be distinguished by:
- the dactylus of P2 is similar in length (0.8–1.0) to the propodus in
M. compacta
and distinctly shorter (0.8) in
M. rhodonia
- chelipeds with well-developed spines on the dorsal face of the palm in
M. compacta
, which are instead very small in
M. rhodonia
.
While the length of the distomesial spine of the P1 merus was used to differentiate these species (Baba, 1997), we found that that the length of this spine varied in our specimens of
M. compacta
and did not always overreach the midlength of the carpus. Also, the P2 dactylus in
M. compacta
is described as clearly shorter than the propodus, but in our specimens, the P2 dactylus was 0.8–1.0 times the propodus length.

The sequences of
M. compacta
from north-western
Australia
and
M. rhodonia
from
New Caledonia
were 1.2% divergent for COI and 0.2% divergent for 16S.
The present specimens represent the first confirmed records of
M. compacta
from
Australia
.
