New records of Crocidura dongyangjiangensis and Crocidura anhuiensis in Jiangxi Province

doi:10.16829/j.slxb.150723

Abstract

Abstract:

In June 2022, four specimens of Crocidura were collected from Wuyi Mountain, Yanshan County, Jiangxi Province. Morphological and phylogenetic analyses showed that one specimen is C. dongyangjiangensis, and the other three are C. anhuiensis. Both species are the first records in Jiangxi Province. The specimen of C. dongyangjiangensis exhibits a light gray-brown color, has a small body type head-body length of 63 mm, tail length of 40 mm, cranial length of 16.57 mm, and a narrow skull. These morphological features are consistent with the description of specimens from Dongyangjiang, Zhejiang Province. The maximum likelihood (ML) tree based on Cytochrome b (Cyt b) gene showed a monophyletic group between this specimen and C. dongyangjiangensis, and the genetic distance (p-distance) between them ranged from 0.6% to 1.8%. The other three specimens identified as C.anhuiensis from Jiangxi are medium-sized shrews. They have head-body length of 75 ? 87 mm and tail length of 52 ? 62 mm (68% ? 77% of head-body length), which are consistent with the morphology of the specimens from Huangshan, Anhui Province. The ML tree showed these three specimens formed a monophyletic group with the C. anhuiensis from Anhui, and their genetic difference (p-distance) was 1.2%.
