Gennadas scutatus Bouvier, 1906

Gennadas scutatus .— Burkenroad, 1936: 83, fig. 59; 1938: 59. Hendrickx & Estrada-Navarrete, 1989: 107; 1996: 32, figs. 9, 17, 22 D. Guzmán & Wicksten, 2000: 929. Guzmán, 2008: 29.

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).
