TALUD VII, St. 36 (25°42’37”N, 110°04’35”W), June 9, 2001, 1M, 1F, MN from surface to 1390 m (TD, 2400 m) (ICML-EMU-12879) GoogleMaps   .

Distribution. Pacific Ocean, in the Kuroshio Current and near Nasca Ridge ( Vinogradov et al. 1996). In the eastern Pacific from the Gulf of California (north to 25°42’37”N) to off Gorgona Island, Colombia, and in the vicinity of the Nasca Ridge ( Vinogradov et al. 1996, Valencia & Giraldo 2012, present study).

Remarks. Found at eight localities during this study although always in very low numbers, A. muratus   had not been reported previously from the Gulf of California or from western Mexico. It features a remarkably wide distribution range, with the original description referring to material from the North Pacific (Kuroshio Current) and off Chile (Nasca Ridge). Considering present records and the material reported by Valencia & Giraldo (2012) off Gorgona Island, about 28 km off the coast of Colombia, A. muratus   appears to occur consistently in the eastern

Pacific.
