Material examined. Holotype: male cl 16.8 mm, cw 26.9 mm ( CNCR 309 ), 36 km N of San Gabriel Mixtepec (approximately 16°20’42.19”N, 97°05’21.61”W; 858 m asl), municipality of San Gabriel Mixtepec, Oaxaca, Mexico, coll. W. J. Schaldach, 10 December 1964.

Remarks. The only specimen existent of E. mixtepensis is the holotype, since its collection in 1964, there have been no new samplings in the type locality, although in some nearby streams, crabs of the species Pseudothelphusa sulcifrons Rathbun, 1898 , have been captured.
