Specimens of a small flying squirrel, Petinomys, recently collected in northern Thailand and West Malaysia show great similarity and appear to belong to a single species. Those from northern Thailand are similar to the holotype of Petinomys morrisi (Carter, 1942). Specimens collected south of the Isthmus of Kra are similar to the holotype of Petinomys setosus (Temminck and Schlegel, 1845). On the basis of color and color patterns, body and skull measurements, and other characteristics the specimens from northern Burma and northern Thailand are considered to represent a slightly larger subspecies of Petinomys setosus, thus becoming P. s. morrisi (Carter, 1942). The smaller, nominate subspecies occurs south of the Isthmus of Kra. Additional material from Borneo is needed to establish whether the latter taxon should be further divided.
