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) .
