最近对壁虎的系统发育研究揭示了壁虎属间出人意料的广泛的同源和多系关系，不清楚的属界，以及在地理上广泛分布的“多面手”支系中表现出特化的、非同形的形态的分类群的嵌套的趋势。这在澳大拉西亚尤其如此，在那里，单系的壁虎受到了关于卢珀龙属的表型华丽的瓣腿壁虎、假壁虎的菲律宾假壁虎的质疑，甚至是Ptychozoon属精心制作的“衍生”降落伞壁虎的质疑。在这里，我们使用针对5060个超服务元素(UCES)的序列捕获来推断42个具有代表性的类群壁虎蜥蜴分类群之间的系统发育关系。我们使用串联的最大似然法和多物种合并方法分析了不同完备度的多个数据集(分别用4715、4051、3376、2366和772个UCE完成10%、50%、75%、95%和100%)。我们的抽样方案解决了这一组中的四个长期存在的系统问题：(1)AreLuperosaurus和Ptychozoon单系进化，这些命名的物种中是否有任何一个真正嵌套在Gekko中？(2)Sulawesi‘s l.的先前系统发育估计。Iskandarias是Melane sianG的姊妹分类单元。我们基因组规模的数据集支持的是什么？(3)是高海拔L。巴拉望岛的古拉特正确地放置在壁虎中吗？(4)最后，神秘的紫杉木在哪里？沙棘属(RhacophorusandL.)棕色瀑布在较高级别的壁虎类系统发育中？我们解决了这些问题；在强有力的支持下，确认了一些先前推断的发现(Ptychozoatia在Gekko内的位置；L。Iskandariandg.Vittatus)；解决未放置分类群的系统位置(L.Gulat，和L.Browni)；和转移L。Iskandari、L.Gulat、L.Browni和Ptychozous的所有成员都在壁虎属上。我们出人意料和新奇的系统推断表明，该物种并不像先前所预期的那样与Ptychozoon或Luperosaurus归为一类，但实际上可能与印度支那的几个壁虎物种关系最近。根据我们已解决的和强有力的支持的系统发育，我们提出了一个新的分类，强调了这60个分类单元最具包容性的原始属名(Gekko)，并将其划分为7个亚属。
Recent phylogenetic studies of gekkonid lizards have revealed unexpected, widespread paraphyly and polyphyly among genera, unclear generic boundaries, and a tendency towards the nesting of taxa exhibiting specialized, apomorphic morphologies within geographically widespread “generalist” clades. This is especially true in Australasia, where monophyly ofGekkoproper has been questioned with respect to phenotypically ornate flap-legged geckos of the genusLuperosaurus, the Philippine false geckos of the genusPseudogekko, and even the elaborately “derived” parachute geckos of the genusPtychozoon. Here we employ sequence capture targeting 5060 ultraconserved elements (UCEs) to infer phylogenomic relationships among 42 representative ingroup gekkonine lizard taxa. We analyze multiple datasets of varying degrees of completeness (10, 50, 75, 95, and 100 percent complete with 4715, 4051, 3376, 2366, and 772 UCEs, respectively) using concatenated maximum likelihood and multispecies coalescent methods. Our sampling scheme addresses four persistent systematic questions in this group: (1) AreLuperosaurusandPtychozoonmonophyletic, and are any of these named species truly nested withinGekko? (2) Are prior phylogenetic estimates of Sulawesi’sL. iskandarias the sister taxon to MelanesianG. vittatussupported by our genome-scale dataset? (3) Is the high-elevationL. gulatof Palawan Island correctly placed withinGekko? (4) And, finally, where do the enigmatic taxaP. rhacophorusandL. brownifall in a higher-level gekkonid phylogeny? We resolve these issues; confirm with strong support some previously inferred findings (placement ofPtychozoontaxa withinGekko;the sister taxon relationship betweenL. iskandariandG. vittatus); resolve the systematic position of unplaced taxa (L. gulat,andL. browni); and transferL. iskandari,L. gulat,L. browni, and all members of the genusPtychozoonto the genusGekko. Our unexpected and novel systematic inference of the placement ofPtychozoon rhacophorussuggests that this species is not grouped withPtychozoonor evenLuperosaurus(as previously expected) but may, in fact, be most closely related to several Indochinese species ofGekko. With our resolved and strongly supported phylogeny, we present a new classification emphasizing the most inclusive, original generic name (Gekko) for these ~60 taxa, arranged into seven subgenera.
