Like other muntjac taxa, there is some taxonomy uncertainty about this species. No recent reviewer (e.g. Ma et al. 1986, Grubb 1977, Groves and Grubb 1990) appears to have examined the holotype; even Grubb (1977) had only photographs of the skull on which to work (P. Grubb pers. comm. to R.J. Timmins, 1997). However, with the recent discovery of several muntjac species in nearby parts of southeast Asia, re-examination of the M. feae holotype is needed, to clarify the species' diagnostic characters, and to verify that captive animals in various Thai collections (including the Dusit Zoo) and a few specimens in the Natural History Museum, London (particularly # 24.1.6.2) truly are M. feae (Grubb 1977, Groves and Grubb 1990).
