Material examined. 2M, 3F in three localities ( Fig. 5 ).

TALUD V. St. 5 (22°00’57”N, 106°40’00”W), December 13, 2000, 1M , MN from surface to ca. 1400 m (TD> 1600 m (ICML-EMU-12977) . TALUD VI. St. 7 (22°21’39”N, 107°01’42”W) , March 14, 2001,1M, 2F, MN from surface to 1305 m (TD, 2100 m) (ICML-EMU-12978) . TALUD VII. St. 29 (25°17’31”N, 109°24’30”W), June 8, 2001, 1F , MN from surface to 1335 m (TD, 2080 m) (ECOSUR-10562) .

Distribution. Circumtropical, usually between 30°N and 30°S. In the eastern Pacific from Mexico to Colombia and Ecuador (García Madrigal 2007, Guillén Pozo, 2007, Valencia & Giraldo 2012, this study).

Remarks. The five known species of Streetsia are distinguished mainly by the length of the double urosomite, the shape and structure of the gnathopod 2 and pereopod VI, and the cuticular pores on the epimeral plates.

Another species of oxycephalid rarely collected. Also rare in the Gulf of California, where Siegel-Causey (1982) found it only in the southern Gulf, where our material was also collected ( Fig. 5 ). It has been found in the Mexican portion of the California Current by Lavaniegos & Hereu (2009).
