On February 2,2021,a bat was captured in an air-raid shelter in Huidong County,Huizhou City,Guangdong Province,south China.The morphological and skull features of the specimen were measured using electronic digital cali-pers.Based on cyt b gene sequences,the phylogenetic tree was reconstructed using maximum likelihood method.The main diagnosis characteristics of the specimen are as follows.The specimen has a medium body size,with head and body length of 53.37 mm,forearm length of 51.60 mm,and weight of 12.70 g.The body hair is vivid and the whole body is golden.The ears are long and narrow,slightly oval.Tragus straight,narrow and pointed.Thumbs,hind-feet and ear edges are brown rather than black.The wings have a special pattern of orange and black.The maximal length of skull is 18.70 mm,and the height of braincase is 7.29 mm.Skull has distinctly elevated frontal region,braincase is globose,the rostrum is broad and short,the lacrimal projections are well developed,and the trend of rostrum to braincase is gentle gradient.Sagit-tal crest and lambdoidal crests are weakly developed.The result of phylogenetic analysis based on the cyt b gene sequence showed that the specimen was clustered with Myotis formosus.Combining morphological and molecular data,the bat is identified as M.formosus,the first record for Guangdong Province.The specimen is deposited in the Institute of Zoology,Guangdong Academy of Sciences.
