Eremorhax fuscus (Muma 1986) combination restored

Eremorhax fuscus Muma 1986: 2 –3, figs. 1–7

Eremocosta fuscus (Muma 1986): Harvey 2002: 451.

Type material. Male holotype from Tutla, Oaxaca, México . Collected 13 December 1948 by E.S. Ross. Deposited at CAS. Female paratype collected from 4 miles north Cuernavaca, Morelos, México , 8 December 1948, collected by E.S. Ross and also deposited in the collection of CAS. Photos of type examined.

Discussion. The shape of the flagellar groove and lack of a VDC (Muma, 1986: fig. 2, p. 25) places this species in the genus Eremorhax . Presence of ctenidia also differentiate it from Eremocosta (see Muma, 1986: fig. 4, p. 25).
