Notes on Southeast Asian Porcupines (Hystricidae, Rodentia) III. On the taxonomy of the subgenus Thecurus Lyon, 1907 (genus Hystrix Linnaeus, 1758)

The characters of the short-tailed porcupines with small nasals from Sumatra, Borneo and the Philippines, genus Hystrix Linnaeus, 1758, subgenus Thecurus Lyon, 1907, have been studied. As a result three species are recognized, namely: H. crassispinis Günther, 1877, H. pumila Günther, 1879, and H. sumatrae (Lyon, 1907). Evidence is brought forward for the valid specific status of these forms and data are presented to supplement the scarce information known about these species.
