Pantomorus fulvus belongs to the Pantomorus auripes species group, revised by Lanteri et al. (1991). It differentiates from Pantomorus auripes mainly because the vestiture is brown, scales are oval instead of round, and setae are longer than in P. auripes.
Pantomorus fulvus is a rare species, endemic to Córdoba province and probably parthenogenetic (Lanteri 1995b, Lanteri & Normark 1995).
Probably associated with vegetation typical of the Espinal biogeographic province.
