Distribution. Indian and Pacific Oceans (Vinogradov et al. 1996). In the eastern Pacific from British Colombia, Canada, to the southern tip of the Baja California Peninsula, Mexico (García Madrigal 2007).
Remarks. Phronimopsis spinifera has been reported by Siegel-Causey (1982) in the central and southern Gulf of California, occasionally abundant but little frequent. Recorded between surface and to 300–500 m depth (Vinogradov et al. 1996, García Madrigal 1982). Related to the California Current system (Bowman 1973, Lavaniegos 2014).
