Not recorded previously by Siegel-Causey (1982) in the Gulf of California, Streetsia steenstrupi has been previously reported from the Mexican portion of the California Current (Lavaniegos & Hereu 2009, Lavaniegos 2014). During our survey it was recorded only in one locality in the Gulf of California (Fig. 5).
