摘要
于2013年分别在广西北流大容山和江西井冈山用蝙蝠竖琴网分别采集到1只和9只蝙蝠标本,主要特征为：体型中型,鼻部前端呈短管状,背部毛基黄褐色,毛尖褐栗色,头骨和牙齿均粗壮。在室内使用Pettersson D500X超声波接收仪录制其静止和飞行状态下的回声定位信号,其超声波为FM型,飞行状态下主频率51.3~59.0 k Hz。根据形态特征鉴定该蝙蝠为毛翼管鼻蝠Harpiocephalus harpia,是广西和江西两省翼手目分布新纪录。对该种蝙蝠雌雄标本进行对比发现,6项外部形态和头骨指标上的差异有统计学意义,支持该种具有性二型现象。标本现保存于广州大学。
In 2013, one forest bat was collected in Darongshan Mountain National Nature Park, Guangxi, and nine bats were collected in Jinggangshan Mountain National Nature Reserve, Jiangxi by using the harp trapping. All specimens were medium size, short tubes nostrils; yellowish-brown pelage base ; brown chestnut pelage tip; and with strong skull and teeth. Using DS00X ultrasound detector, the echolocation sounds of bats were recorded in resting state and flying state, respective- ly, and the main frequency was 51.3 -59.0 kHz in flying state （FM type）. According to the external and skull characteristics, these bats were identified as lesser hairy-winged bat Harpiocephalus harpia, which represented the first record in Guangxi and Jiangxi. Significant morphological differences between different sexes （t-test） indicated an occurrence of sexual di- morphism within this species. The specimens above were deposited in Guangzhou University.
