Fea's muntjacs, Muntiacus feae, are similar in size to Indian muntjacs, Muntiacus muntjak, which measures 57 cm at shoulder height. Unlike Indian muntjacs, in which males are taller than females, Muntiacus feae females are taller than males by 6 to 7 cm. The average weight of an adult Muntiacus feae is 22 kg. This small deer is uniformly brown in colour with light stripes down the back of the legs and yellow hair at the crown of the head and around the pedicles. Tufts of hair on the forehead may be lighter in colour. The relatively long tail is fringed with white hair. The elongated pedicles of males' antlers converge and each has a black line running up its center. The antlers are slightly longer than those of other barking deer (e.g. black muntjac Muntiacus crinifrons, which has antlers that do not exceed 60 mm in length). The long pedicles of muntjacs may be an adaptation to minimize the energy required to regrow antlers after they are shed, as the tropics are relatively nutrient-poor. Males have tusk-like canines that are 1 to 2 cm long.
