四川七种蝙蝠的核型

本报道了四川地区7种蝙蝠的核型。菊头蝠科2种，即角菊头蝠(Rhinolophus comutus)的核型为2n=62，FN=60；栗黄菊头蝠(R．ssinicus)的核型为2n=36，FN=60。蹄蝠科1种，即大蹄蝠(H．armiger)的核型为2n=32，FN=60。蝙蝠科3种，即伏翼(Pipistrellus abramns)的核型为2n=26，FN=44；南蝠(Iaio)的核型为2n=50，FN=48；山蝠(Nyctalus velutinus)的核型为2n=36，FN=50。犬吻蝠科的皱唇蝠(Tadarida teniotis)的核型为2n=48，FN=62。南蝠的核型为首次报道，但栗黄菊头蝠的核型2n=36与安徽张维道报道相同，而与印度和斯里兰卡同种R．rouxii的核型2n=56迥异。分布在中国的栗黄菊头蝠R．sinicus应为独立种而不是R．rouxii的中国亚种。另5种蝙蝠的核型与前人研究结论基本一致。

Karyology of Seven Species Bats from Sichuan, China

The karyotypes of seven species bats from Sichuan, China were examined(namely:Rhinolophus cornutus, Rhinolophus sinicus, Hipposideros armiger, Ia io, Pipistrellus abramus, Nyctalus velutinus, and Tadarida teniotis). It is essentially identical to those previour reports about the karyotypes of Rhinolophus cornutus (2n = 62, FN = 60),Hipposideros armiger (2n = 32, FN = 60), Ia io (2n = 50,FN = 48),Pipistrellus abramus (2n = 26, FN = 44), Nyctalus velutinus (2n = 36, FN = 54), and Tadarida teniotis (2n = 48, FN = 62). R. sinicus should be named as a species instead of a subspecies of R. rouxii. The karyotype of Ia io is reported for the first time.
