摘　　要：云南大窑大百草岭和永德大雪山分布的具有溪流繁殖习性的小型蟾蜍是2种新的未描述蟾蜍新种,它们都与哀牢蟾蜍(Parabufo Bufo ailaonica)有相似的形态和习性:(1)体型较小;(2)无鼓膜;(3)蝌蚪口部无吸盘;(4)产卵于山区溪流。因此,我们为其建立了1个新属(Parabufo gen.nov.),并将这2个新种分别命名为Parabufo baicaolingensis sp.nov.和Parabufo xueshanensis sp.nov.,将哀牢蟾蜍(Parabufo Bufo ailaonica)移入该新属。3个种之间有明显的形态差异:(1)体型大小:雄性的百草岭蟾蜍45.0~50.2 mm,雪山蟾蜍53.1~62.0 mm,哀牢蟾蜍41.1 mm,雌性的百草岭蟾蜍66.0~70.5 mm,雪山蟾蜍(缺少样本),哀牢蟾蜍52.0~55.0 mm;(2)皮肤:百草岭蟾蜍皮肤较为粗糙并密布大小不一的疣粒和痣粒(尤其雌蟾),雪山蟾蜍背部皮肤较光滑且疣粒很少,哀牢蟾蜍背部皮肤较为光滑但疣粒明显且大小较一致。There are two new undescribed species of small-sized toads with stream-breeding habits which distributed in Dayao Dabaicaoling mountain and Yongde Daxueshan mountain in Yunnan province of China.Both of these two species of toads have similar morphology and habits to the Ailao mountain toad Parabufo Bufo ailaonica:(1)smaller body size;(2)absence of tympanic membrane;(3)absence of suckers at the mouth of tadpoles;(4)spawning in mountain streams.Accordingly,we establish a new genus Parabufo gen.nov.for them.Besides,the two new species of toads were named as Parabufo baicaolingensis sp.nov.and Parabufo xueshanensis sp.nov.respectively.Concurrently,the Parabufo Bufo ailaonica was moved into this new genus Parabufo gen.nov..These three species have obvious morphological differences from each other:(1)body size:45.0~50.2 mm for P.baicaolingensis males,53.1~62.0 mm for P.xueshanensis males,41.1 mm for P.ailaonica males,and 66.0~70.5 mm for P.baicaolingensis females,lack for P.xueshanensis females,52.0~55.0 mm for P.ailaonica females.(2)Skin:The skin of the P.baicaolingensis is rough and densely populated with warts and moles of different sizes(especially in females),the back of P.xueshanensis is smooth and has few warts,and the back of P.ailaonica is smooth but with obvious warts of consistent size.
