Distribution.
Previously known from Sibuyan Sea, Davao Gulf off Southeastern Mindanao,
Ternate
,
Moluccas
, Sulu Archipelago,
Indonesia
, Southwestern
Australia
;
37–
100 m
. Now also known from South
China
Sea;
6.7–
79 m
. The present record extends the bathymetric range of the species from 37–100 to
6.7– 100 m
Remarks.
The specimens agree essentially with the description of
Galathea consobrina
De
Man
, 1902
, with the exceptions of features of the Mxp3 merus: most of the specimens examined have two stout spines on the extensor margin, but the male of MBM215139 has a very small spine between the two stout spines. Three hepatic spines are consistently present in most of the specimens examined, as in the
holotype
, but one male (MBM 215213) has five spines. This is the first record for the species from the Chinese waters.
