Abstract

Abstract: 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 clade 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 clade.

标题菲律宾北部鳞趾壁虎(爬行纲:鳞趾壁虎科:鳞翅目)分类订正及四新种记述
摘要:最近对鳞翅目蜥蜴属的gekkonid蜥蜴进行了更高级别的系统发育分析,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。对多点数据集的新系统发育分析表明,多达五个以前未描述的鳞趾壁虎物种级谱系仅出现在群岛的北部。在这里,我们评估了亚马细趾虫-巴廖布里虫分支中的细趾虫物种多样性,并描述了吕宋岛和周围小岛群的四个新森林物种。有趣的是,这些物种是在吕宋岛和周边岛屿上描述的第一个特有的鳞翅目分类群。在近半个世纪以来对菲律宾鳞趾壁虎多样性的首次综述中,我们使用了一套形态学特征和分子数据来界定进化谱系。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种区分开来;所有这些也是单系群,在我们对线粒体ND2基因的系统发育分析中是分离的。这项研究显著增加了菲律宾已知的鳞趾壁虎的数量,从7只增加到11只,这可能仍然低估了这个研究不足的分支的物种多样性。
