The single species, N. hainanensis, is known only from Hainan Island off southern China. The back is rusty brown with gray, and there is a long, black middorsal stripe. The sides are washed with olive-yellow, and the underparts are pale gray or yellowish white. The ears, feet, and tail are nearly naked, having only minute, scattered hairs.
Females have two pectoral and four abdominal mammae.
From Hylomys, Neohylomys is distinguished by larger size, a relatively much longer tail, and a more pronounced dorsal stripe. The Johns Hopkins University Press. All rights reserved.
