, stn AGT-4, off Antofagasta (

,

), “
PUCK
” expedition, RV “Sonne",
April–May 2001
.
Description
. Rostrum short, directed upwards as strong spine (
Fig. 2
b), overreaching distal part of antennal peduncle, flanked by 2 lateral spines. Carapace subpentagonal densely covered by simple and scale-like tubercles; gastric region armed with strong, long spine of almost half postorbital carapace length; 2 other minor spines on anterior epigastric region (
Fig. 2
a); antennal spines absent; anterolateral spines strong, reaching base of cornea.
Cheliped short, length almost as long as postorbital carapace length, palm slightly shorter than fixed fingers, covered by scale-like tubercles (
Fig. 2
c) as also carpus (
Fig. 2
d). Pereiopods as long as one and one-half times carapace length, surface covered by scale-like tubercles, dactyl armed ventrally by row of more than 15 spines (
Fig 2
e).
Remarks
. The specimen collected by the “PUCK” expedition without doubt belongs to this species, because
G. rostrata
is easily distinguishable from all other species of the genus (
Macpherson 2007
).
The report of
G. rostrata
from Juan Fernandez archipelago is erroneous (see above as
G. bellis
).
Khodkina (1975)
reported
G. rostrata
from stn 220, 254 from shores of north of
Chile
and from stn 1968. Thus, this constitutes a new record to
Chile
.
