Material examined
. Seven specimens.
TALUD
XV, St. 17 (
26º20'24"N
114º13'07"W
),
July 31, 2012
, 3 M (CL
7.6–8.9 mm
) and 3 F (CL
7.2–9.1 mm
), BS operated at
2111–2136 m
(EMU–10880).
TALUD
XVI–B St. 25 (
31º48'N
116º55'28"W
),
May 26, 2014
, 1 M (CL
8.9 mm
), BS operated at
807–814 m
(EMU–10881).
Distribution
. Cosmopolitan. In the eastern Pacific, it is known from off the west coast of the Baja California Peninsula,
Mexico
(25ºN), to Lobos de Tierra Island,
Peru
, and Clarion Island (
Burkenroad 1938
;
Hendrickx & Estrada-Navarrete 1996
).
Guzman (2008)
reported it from off
Chile
. Based on the material examined herein the northernmost distribution limit is extended to
31º48'N
116º55'28"W
.
Distribution in western
Mexico
. As in the case of the two previous species,
G. scutatus
has been reported only in the California Current area, but in this case it had not been previously collected from the northern cooler portion of this current in western
Mexico
(
Hendrickx & Estrada-Navarrete 1996
). The material examined herein however, provide one record in that cooler portion of the California Current (see
Fig. 1
).
Remarks
. Records in the eastern Pacific are very scarce. The record from
Peru
was provided by
Méndez (1981)
and there is a doubtful record from off
Panama
(
Boone 1930
).
