昆嵛林蛙胚后发育的初步观察

Preliminary Observations on Postembryonic Development of Rana kunyuensis

摘要: 昆嵛林蛙(Rana kunyuensis，Lu et Li 2002)是新近在山东文登昆嵛山发现的蛙科(Ranidae)蛙属(Rana)林蛙群(Wood-frogs) 的一新种。我们在23.7-26.0℃的条件下，观察了其胚后发育全过程中的形态变化。该蛙胚后发育可划分为19期，历时约49 d。唇齿式多为Ⅰ∶1-1/Ⅲ、少数Ⅰ∶1-1/Ⅱ∶1-1，为昆嵛林蛙这一新种的确立提供了形态学依据。

Abstract: Rana kunyuensis,Lu et Li 2002 was newly founded in Mt.Kunyu,Shandong Province.Its postembryonic development was observed with microscopes in laboratory at 23.7-26.0 ℃.It took about 49 days to develop from operculum completion to metamorphosis completion,experiencing 19 stages.The labial teeth formula of tadpoles was mainly Ⅰ∶1-1/Ⅲ,and occasionally Ⅰ∶1-1/Ⅱ∶1-1,which were different from R.chensinensis,R.japonica,R.chaochiaoensis and R.huanrenensis,but similar to R.amurensis.The latter further confirmed that Lu and Lis finding.
