We review the recent discovery of multiple populations of the enigmatic, semi-aquatic Sphenomorphus Group skink, Parvoscincus leucospilos Peters, and investigate the morphological and genetic diversity of isolated, allopatric populations of this unique skink. Our investigations support the recognition of four unique evolutionary lineages distributed across Luzon Island in the Philippines, three of which are herein described as new species (P. tikbalangi sp. nov., P. manananggalae sp. nov., and P. duwendorum sp. nov.). All four recognized species are genetically divergent in both mitochondrial and nuclear DNA sequences, and morphologically distinct. The description of three new Luzon Island endemic species adds to the growing body of literature suggesting that mechanisms driving the accumulation of vertebrate diversity in the Philippines may vary regionally across the archipelago.
我们回顾了近期对神秘的半水生棱蜥属石龙子——白纹小棱蜥（Parvoscincus leucospilos Peters）多个种群的发现，并研究了这种独特石龙子隔离的异域种群的形态和遗传多样性。我们的调查支持了对分布在菲律宾吕宋岛的四个独特进化谱系的识别，其中三个在此被描述为新物种（新物种提克巴朗棱蜥、马尼南加拉棱蜥和杜温多棱蜥）。所有四个被认可的物种在线粒体和核DNA序列上都存在遗传差异，且形态各异。对吕宋岛三个新特有物种的描述丰富了不断增长的文献资料，表明驱动菲律宾脊椎动物多样性积累的机制可能在整个群岛的不同区域有所不同。
