本文对马达加斯加石龙子属Madascincus的一组分类学上混淆的密切相关物种进行了研究，目前包括名义种M。polleni，M. intermedius和M. stumpffi。基于线粒体和核DNA序列（ND 1和RAG 2基因，分别）的综合分析，和形态学检查，我们提供的证据，在这个复杂的存在至少四个不同的进化谱系：Madascincus stumpffi; Madascincus arenicola sp. nov. from北方马达加斯加;和两个神秘的物种形态学上类似的命名类型的M. polleni和M.中间体后两个物种，虽然遗传上不同，似乎是无法区分的形态和它们的分类地位不能解决，直到更好的采样将是可用的。
The present paper constitutes a study on a taxonomically confusing group of closely related species belonging to the Malagasy skink genus Madascincus, currently encompassing the nominal species M. polleni, M. intermedius and M. stumpffi. Based on combined analyses of mitochondrial and nuclear DNA sequences (ND1 and RAG2 genes, respectively), and morphological examination, we provide evidence for the existence of at least four distinct evolutionary lineages within this complex: Madascincus stumpffi; Madascincus arenicola sp. nov. from northern Madagascar; and two cryptic species morphologically similar to the name-bearing types of M. polleni and M. intermedius. The two latter species, although genetically distinct, appear to be morphologically indistinguishable and their taxonomic status cannot be resolved until a better sampling will be available.
