Abstract
Semnopithecus schistaceus Hodgson, 1840 belongs to subfamily Colobinae, family Cercopithecidae. This species was once mixed with S. entellus. The conservation status of this species is Least Concern (LC) in IUCN. In China, this species has been considered as Critically Endangered (CR) by the Red List of China's vertebrates. In this study, the complete mitogenome of S. schistaceus was determined. The mitogenome is a circular molecule of 16,534 bp in length, containing 13 protein－coding genes, 2 ribosome RNA genes, 1 light strand replication origin (OL), 22 transfer RNA genes, and 1 non－coding region. We reconstructed a phylogenetic tree based on Bayesian inference for 19 primates species. The Cyt b p-distance is 0.029 between S. schistaceu and S. entellus. Thus, the taxonomic status of these two species remains to be further studied.
