Over the past three decades, they have been placed variably in the genera Dusicyon ( Clutton-Brock, et al., 1976 ; Wozencraft, 1989 ), Canis ( Langguth, 1975 ; Van Gelder, 1978 ), Pseudalopex ( Berta, 1987 ; Wozencraft, 1993 ; Tedford et al., 1995 ), and Lycalopex ( Zunino, 1995 ; Wozencraft, 2005 ).

As Pseudalopex and Lycalopex have largely come to describe the same genus, either classification is acceptable, although modern practice is to give Lycalopex prominence.

Current usage lists Pseudalopex ( literally: " false fox ") as synonymous with Lycalopex (" wolf fox "), with the latter taking precedence.

The IUCN, for instance, retains the use of Pseudalopex while also acknowledging Lycalopex as a legitimate alternative.

They were later reclassified to Lycalopex ( via Pseudalopex ) by Langguth in 1975.
