摘要
昆嵛林蛙 (Ranakunyuensis,LuetLi 2 0 0 2 )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 2 3 7～ 2 6 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 4 9d。唇齿式多为Ⅰ∶1- 1/Ⅲ、少数Ⅰ∶1- 1/Ⅱ∶1- 1。
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.
