Distribution. Circumtropical and in the Mediterranean Sea. In the eastern Pacific from California to Costa Rica, Panama, Colombia, and Chile (Vinogradov et al. 1996, García Madrigal 2007, Valencia & Giraldo 2009, Valencia et al., 2013, Violante-Huerta et al. 2021, this study).
Remarks. Oxycephalus clausi is easily recognized for the presence of a medial tooth on the ventral margin of pleonites 1‒3, and by the shape of the anterodistal corner of the carpus gnathopods 1 and 2 which are produced in a sharp point.
Siegel-Causey (1982) reported Oxycephalus clausi as common in the Gulf of California, where it was collected in the northern, central and southern Gulf. Our results indicated a similar pattern (Fig. 2). In the Mexican portion of the California Current, it has been reported as rare by Lavaniegos & Hereu (2009) and by Lavaniegos (2014; 7.5% of the samples). It inhabits predominantly in surface waters (Zeidler 1999).
