17 Sumatran rhinos were sequenced for 953 bases of 12S and 16S mitochondrial sequences. The 17 rhinos came from Sumatra (6), Borneo (4) and West Malaysia (7). Four haplotypes were identified. Only one haplotype was found in the samples from Borneo, one haplotype in samples from West Malaysia, and two haplotypes from Sumatra animals. Four sites were variable, position # 133, 179, 194 in the 12S sequence and position # 313 in the 16S sequence. The Borneo haplotype differed by 2 positions from Sumatran and 3 positions from Malaysian. West Malaysia and Sumatra vary by one position for one of the Sumatran haplotypes and by two positions for the other Sumatran haplotype. This supports the subspecies designation by Groves (1967) placing the Malayan and Sumatran populations together as D.s.sumatrensis and the Borneo population as D.s. harrissoni.
