TALUD XII, St. 13 (17°45'16''N, 102°00'29''W), Mar 30, 2008, 1 male (CL 36 mm), BS operated at 1199– 1100 m (ICML-EMU-12303). TALUD XV, St. 5C (23°16'42"N, 110°54'55"W), Aug 5, 2012, 1 juv.

TALUD XVI-B, St. 19 (30º38'N, 116º31'40"W), May 25, 2014, 1 female (CL 55 mm), BS operated at 1385–1433 m (ICML-EMU-12302); St. 22 (30°56'N, 116°40'33"W), May 27, 2014, 1 juv. (CL 16 mm), BS operated at 1296–1340 m (ICML-EMU-12304A); St. 27 (31°42'21"N, 117°13'W), May 27, 2014, 1 juv. (CL 27 mm), BS operated at 1394–1397 m (ICML-EMU-12304B). Distribution. Cosmopolitan in temperate and tropical zones (Atlantic, Pacific and Indian Oceans) (Ibarra Rivera & Hendrickx 2008; Meland & Ass 2013). While reviewing the western Mexico material of the SIO and of the Mazatlán collection, Ibarra Rivera & Hendrickx (2008) mostly found material from within the Gulf of California (Ibarra Rivera & Hendrickx 2008: fig. 22). The material reported herein is from six localities along the west coast of the Baja California Peninsula, ranging roughly from 22°N to 32°N (Fig. 5). Additional material from SW Mexico examined herein add a new record (17°45’16”N) for this species in this area (see Ibarra Rivera & Hendrickx 2008).
