中文摘要: |
2019年7月于海南岛儋州市石花水洞网捕到1只蝙蝠,形态特征、头骨特征及线粒体Cyt b基因序列鉴定证实其为长舌果蝠(Eonycteris spelaea),该物种为海南岛蝙蝠分布新记录种。其主要鉴别特征为:中等体型,前臂长69.6 mm;第二指无爪;有一短尾,尾长12.9 mm,明显突出于股膜之后;肛腺发达;头骨较大,头骨和吻部相对较长,颅全长35.2 mm,吻长11.4 mm。本文报道了海南岛长舌果蝠的外部形态、头骨特征以及基于Cyt b基因序列的系统发育树结果,并与该物种已报道的数据进行了比较。 |
英文摘要: |
In July 2019, a bat was captured at Shihua Cave in Danzhou of Hainan Island and identified as Eonycteris spelaea by morphological measurements, skull characteristics and analysis on mitochondrial Cyt b gene. It is medium-sized bat with a forearm of 69.6 mm and without a claw on the second finger of the forelimb (Table 1). A short tail of 12.9 mm is prominent behind the femoral membrane and the bat has well-developed anal gland (Table 1 and Fig. 1). The greatest length of skull (GTL) is 35.2 mm and the rostral length (RL) is 11.4 mm (Table 1). The phylogenetic relationships of E. spelaea with its close species inferred from Cyt b gene sequences display that the Hainan bat and E. spelaea cluster a branch in high bootstrap value (Fig. 2). This is the first record of this species in Hainan Island. In the present study, morphological characters, the skull characters and the phylogenetic tree based on Cyt b gene sequences were represented detailedly. Comparisons were also performed between our findings and published data about the species recorded in other areas. |
