The genus was first described in 1942, by E. S. Riggs, who identified the sister genus
Zodiolestes at the same time, and assigned to the family
Mustelidae. It belongs to the subfamily
Oligobuninae. Five species have been identified in the genus:
Promartes darbyi,
P. gemmarosae,
P. lepidus,
P. olcotti, and
P. vantasselensis, three of which were originally identified as members of
Oligobunis. ==Notes==
