Several recent studies have demonstrated that a tremendous amount of biological diversity can be masked by phenotypic similarity in a cryptic species complex. It has been speculated that the widely distributed and relatively common Southeast Asian frog Limnonectes kuhlii represents a complex of multiple species. The phylogeny within the L. kuhlii Complex is estimated in this study based on approximately 2400bp of mtDNA data (tRNA(Phe), 12S, tRNA(Val), and 16S genes) from 244 individuals representing multiple populations from throughout the known distribution of this anuran. Analyses are conducted using parsimony, maximum likelihood and Bayesian methods. The results suggest that what has been recognized historically as a single species is a complex of more than 22 distinct evolutionary lineages, 16 of which are currently subsumed under the nominal L. kuhlii. Several cases of sympatric lineages were detected, and in all cases co-occurring lineages were not each other's closest relatives.
几项最近的研究表明，在一个隐存种复合体中，大量的生物多样性可能被表型相似性所掩盖。有人推测，广泛分布且相对常见的东南亚青蛙 Limnonectes kuhlii 代表了多个物种的复合体。本研究基于来自 244 个个体的约 2400bp 的 mtDNA 数据（tRNA(Phe)、12S、tRNA(Val)和 16S 基因），估计了 L. kuhlii 复合体的系统发育。使用简约法、最大似然法和贝叶斯法进行分析。结果表明，历史上被认为是单一物种的物种实际上是由 22 个以上不同进化谱系组成的复合体，其中 16 个谱系目前归入名义上的 L. kuhlii 之下。检测到了几个同域谱系的情况，在所有情况下，共存的谱系并不是彼此最亲近的近亲。
