摘要

The tube-nosed bat genus Murina is widely distributed across the tropical and subtropical forests of Asia, with many species exhibiting overlapping ecological niches and distribution ranges. Among them, M. annamitica and M. walstoni have been documented in several forest types (including semi-evergreen and deciduous forests) throughout the Indo-China Peninsula. During a bat survey conducted at Xishuangbanna, China (April-May 2019), fifteen medium-sized Murina specimens were collected and subsequently identified through an integrative taxonomic approach as M. annamitica and M. walstoni. These specimens represent the first documented records of both species in China and the broader East Asian region. To improve the systematics and phylogenetics of Murina, we generated the complete mitogenomes of both species, with 17,116 bp for M. annamitica and 16,738 bp for M. walstoni. Both mitogenomes contain the typical set of 37 mitochondrial genes, and the predominance of heavy-strand-encoded genes is consistent with previously reported Murina mitogenomes. Prior to this study, 31 Murina species had been recorded from China. The discovery of M. annamitica and M. walstoni raises the total number of Murina species recorded in China to 33. These findings suggest that the true species diversity of Murina in China is likely underestimated and underscore the importance of increased geographic sampling in specialized habitats such as tropical rainforests of southwestern China and the Qinghai-Tibet Plateau.
