最近的更高层次的系统发育分析蜥蜴属Lepidodactylus发现了一系列未被识别的物种多样性，特别是在菲律宾群岛。多位点数据集的新系统发育分析表明，多达五个，以前未描述的，物种水平的鳞趾壁虎谱系发生在北方部分的群岛。在这里，我们评估的Lepidodactylus yami-balius沼泽地的Lepidodactylus物种多样性和描述四个新的森林物种吕宋岛和周围的小岛群。有趣的是，这些物种是第一个特有的Lepidodactylus分类群描述吕宋岛和周边岛屿。在这第一次审查菲律宾鳞趾壁虎的多样性在近半个世纪，我们使用一套形态特征沿着与分子数据来划定进化谱系。本文中描述的所有物种都可以通过一系列离散的外部特征与同类物区分开来;所有物种也都是单系群，在我们的线粒体ND 2基因系统发育分析中分离。这项研究将菲律宾已知的鳞趾壁虎数量从7只增加到11只，这可能仍然低估了这个未被充分研究的沼泽地的物种多样性。
Recent higher level phylogenetic analyses of gekkonid lizards of the genus Lepidodactylus uncovered an array of unrecognized species diversity, particularly within the Philippine archipelago. Novel phylogenetic analyses of multilocus data sets suggest that as many as five, previously undescribed, species-level lineages of Scaly-toed Geckos occur in just the northern portions of the archipelago. Here, we evaluate Lepidodactylus species diversity in the Lepidodactylus yami-balioburius Glade and describe four new forest species from Luzon Island and surrounding minor island groups. Interestingly, these species are the first endemic Lepidodactylus taxa described from Luzon proper and peripheral islands. In this first review of Philippine Scaly-toed Gecko diversity in nearly half a century, we use a suite of morphological characters along with molecular data to delimit evolutionary lineages. All species described in this paper can be distinguished from congeners by an array of discrete external traits; all are also monophyletic groups, separated in our phylogenetic analyses of the mitochondrial ND2 gene. This study increases significantly the number of known Scaly-toed Geckos in the Philippines from 7 to 11, which is likely still an underestimate of the species diversity in this understudied Glade.
