Elsia indica Giles, 1890: 250‒251 .

Material examined. 1M in one locality ( Fig. 1 ).

TALUD IV. St. 22 (24°17’20”N, 108°50’30”W), August 26, 2000, 1M , MN from surface to 1325 m (TD, ca. 1800 m) (ICML-EMU-12945) .

Distribution. Circumtropical, from 30°N to 40°S; Mediterranean and Red Seas ( Vinogradov et al. 1996). In the eastern Pacific from California to the Galapagos Islands (García Madrigal 2007, this study).

Remarks. Only two species of Glossocephalus are known to date, and the male reported herein fits well with the characteristics of G. milneedwardsi , including the typical eyes of this species.

Another rare species in the Gulf of California, reported by Siegel-Causey (1992) from both the northern and southern Gulf, but only in the southern Gulf in our study ( Fig. 1 ). Lavaniegos & Hereu (2009) reported this species from the Mexican portion of the California Current .
