Pithecheir parvus Kloss, 1916 . J. Fed. Malay St. Mus., 6:250.

TYPE LOCALITY: Malay Peninsula, Selangor, Bukit Kutu, near Kuala Kubu, 3,400 ft .

DISTRIBUTION: Malay Peninsula (Pahang and Selangor).

COMMENTS: Originally described as a subspecies of P. melanurus, but is a distinctive species endemic to Malay Peninsula (Musser and Newcomb, 1983; Muul and Lim, 1971). Karyotype has same diploid number as Hapalomys longicaudus, but is uninformative about inferring phylogenetic relationships (Yong, et al., 1982). Spermatozoal morphology very distinctive (no apical hook), unlike that of any other Sundaic endemic (Breed and Yong, 1986), and resembles sperm of Sulawesian Lenomys and Eropeplus (Breed and Musser, 1991) .
