Distribution.
Previously known from East
China
Sea,
Japan
, East of Masbate, Sulu Archipelago, Eastern of Rockhampton, Queensland, Southwestern
Australia
;
31–
382 m
. Now also known from South
China
Sea;
78–
194 m
. The present report extends the bathymetric range of the species in the East
China
Sea from
84–130 m
to
55–
139 m
.
Remarks.
The specimens agree well with the descripton of
Miyake & Baba (1964)
, with the exception of the Mxp3 merus in three males (MBM
150262
). The three male specimens have three spines on the flexor margin, in which the proximal spine is strong and the distal and median spines are much smaller than the proximal. The
holotype
of
G. balssi
has two spines on the flexor margin of the Mxp3 merus, the distal of which is smaller.
