Abstract

• Natma Taung (Mount Victoria) is the highest mountain in the Chin State of the northern part of Myanmar and its elevation is about 10,500 feet. The small mammals are more diverse at Natma Taung National Park. In the present study, seven newly recorded species were selected from Natma Taung National Park in Northern Myanmar. The two species, Apodemus ilex (wood mouse) and Ethenomys eleusis (oriental-vole), were sequenced to investigate the phylogeographic distribution of mouse species at different study sites of Natma Taung National Park using the mitochondrial cytochrome b gene. One species Episoriculus caudatus (brown-toothed shrew) was studied based on phylogenetic analysis of the mitochondrial Cytb gene partial (669 bp). The newly recorded species Apodemus ilex had 0.02% genetic distances with AY389018 China Gen bank references. Ethenomys eleusis was 0.03% with KT899700 and Episoriculus caudatus was 0.04% with Gen bank of MK962210 from China. The mt Cytb gene sequences analysis showed that Natma Taung National Park had high species diversity and genetic variation. The study of genetic distances and the phylogenetic relationships of the species will support a better understanding of the ecology, species diversity, and geographic distribution of the species.
