广东发现泰坦尼亚彩蝠及其回声定位声波特征

Discovery of Titania′s Woolly Bat(Kerivoula titania) in Guangdong Province(China) and Its Echolocation Calls

于2014年4月在广东封开黑石顶省级自然保护区,使用竖琴网采集到4只体形较小的雌性蝙蝠样本,其形态特征为无鼻叶结构,具漏斗状耳廓和披针形耳屏,前臂长32.30~34.11 mm,胫骨长16.47~17.72 mm;头骨较扁平,颅全长13.99~14.59 mm,脑颅高4.66~5.17 mm;齿式为2.1.3.3/3.1.3.3=38。经鉴定为泰坦尼亚彩蝠（Kerivoula titania）,是广东省翼手目分布新纪录。首次报道了该种蝙蝠的回声定位声波特征,声波类型属于调频（FM）型,峰频（114.3±3.9）k Hz,带宽（117.8±12.3）k Hz,脉冲持续时间（1.7±0.3）ms,脉冲间隔时间（12.9±1.3）ms。标本现保存于广州大学生命科学学院。

This study present a new record of bat distribution in Guangdong Province, China. Four small female bats were collected by harp traps in evergreen forest mixed with sparse bamboo in Nature Reserve of Guangdong Fengkai Heishiding in April, 2014. They were identified as Titania′s woolly bat（Kerivoula titania） by checking their pelage colour, external morphology, skull and dental characteristics. Their dorsal surface hairs are greyish, with black in basal, light grey in mid-parts and dark grey on tips. The ventral surface hairs are black-brown, with black in roots and grey-brown on tips with funnel-shaped ears and long-lanceolated tragus and no extra noseleaf structure. Their body is small with forearm length 32.30﹣34.11 mm and tibia length 16.47﹣17.72 mm. The greatest length, of their flattened skull is 13.99﹣14.59 mm with the height of 4.66﹣5.17 mm. The dental formula of specimens is 2.1.3.3/3.1.3.3 = 38（Fig. 1, Fig. 2, Table 1）. Petterson D500x（Sweden） was used to record the echolocation calls in free flying status indoor and data analyse was conducted by Bat Sound v.4.1.4 use SPSS v.19 software. Their echolocation calls were frequency modulated（FM） with high main frequency 114.3 ± 3.9 k Hz, long frequency bandwidth 117.8 ± 12.3 k Hz with time duration 1.7 ± 0.3 ms and interval 12.9 ± 1.3 ms（Fig. 3, Table 2）. This was the first time to describe the echolocation calls for this species. The discovery of K. titania in Nature Reserve of Guangdong Fengkai Heishiding added a new species record in Guangdong province, China. The specimens were preserved in School of Life Sciences, Guangzhou University.
