摘要
[目的]探讨安龙仙鹤坪产斑腿泛树蛙的形态特征。[方法]从贵州安龙仙鹤坪自然保护区采获20雄13雌斑腿泛树蛙标本,腹腔注射10%的甲醛溶液保存,对其形态特征进行观察。[结果]安龙产斑腿泛树蛙属于泛树蛙属(Polypedates),与道真、台湾产斑腿泛树蛙的形态特征相似。安龙产斑腿泛树蛙指间无蹼,第四趾外侧蹼达远端第二、第三关节下瘤之间;多数标本体背面有"X"形花斑,股后均有较细密的网状花斑。雄性具一对咽侧下内声囊。其栖息环境颇广泛,白天多隐蔽,黄昏时出来活动。产卵季节颇长,以5、6月为繁殖盛期,一般当年完成变态,以陆栖为主。[结论]该研究为斑腿泛树蛙的进一步研究奠定了基础。
[Objective] The aim was to discuss the morphological characteristics of Polypedates megacephalus distributing at Xianhe flat of Anlong.[Method] The P.megacephalus samples,20 male adults and 13 female adults,were collected from Xianhe flat nature reserve of Anlong in Guizhou Province and conserved with 10% formaldehyde solution injected into abdomen,their morphological characteristics were observed.[Result] The P.megacephalus distributing at Anlong belonged to Polypedates and its morphological characteristics were similar to that of P.megacephalus distributing at Daozhen and Taiwan.There was no web among fingers P.megacephalus distributing at Anlong and the web outside its fourth toes reached between the second and third subarticular tubercle.The body dorsum of most samples had X variegation and there all had more fine reticular variegation behind its thigh.The male adult had a pair of internal vocal sac under corpora allata.Its habitat was wide and it used to hide in day and activate from dusk.It had long oviposition period and its thriving propagation season was in May and June.It usually accomplished metamorphosis in current year.It was mainly lived on land.[Conclusion] The research laid the foundation for further study on P.megacephalus.
