摘　　要：2015年8月在湖南省炎陵县用蝙蝠竖琴网采集到森林型蝙蝠3只,其主要特征:体型较大,鼻孔管状,体毛厚密,后肢、翼膜与尾膜均覆盖棕色绒毛,前臂长47.8~52.2 mm,颅全长20.66~22.21 mm,雄性个体较雌性小.经鉴定为翼手目蝙蝠科管鼻蝠亚科的毛翼管鼻蝠(Harpiocephallus harpia),为湖南省蝙蝠分布新纪录.同时,通过Max Ent生态学模型对毛翼管鼻蝠在中国潜在分布区进行建模与预测,结果提示低温是影响该物种分布的重要限制因子,该种在中国的潜在分布区域集中于华南沿海地区,海南分布区有待进一步验证.In August 2015, through harp traps forest-habitated bat was collected from Yanlin county, Hunan province. Three specimens are medium-sized with distinct tubed nostrils and thick red-brown pelages; the hind legs, wing membrane and uropatagium membrane are covered with fine hair. The forearm ranges from 47. 8 mm to 52. 2 mm, while the greatest skull length is 20. 66 ？22. 21 mm. Although our sampling is limited, the males are smaller than the female, which is consistent with pervious conclusion of sexual dimorphism. They were iden-tified as Harpiocephalus harpia, a new chiropteran record in Hunan province, China. Meanwhile, MaxEnt eco-logical model was used to predict the potential distribution of H. harpia within China. Our results indicate that low temperature is a key limiting factor that influences its distribution and coastal area of South China is its main distribution area. Furthermore, the predicted distribution within Hainan province needs to be further verified in future.
