盾叶蜈蚣在多足类系统学中占有重要地位，是其他所有儿童足类的姊妹类群，但自一个世纪前Verhoef的形态研究以来，其内部系统发育还没有得到全面的评价。根据对5个分子标记(完整的18S rRNA、2.2kb的28S rRNA片段、16S rRNA、细胞色素C氧化酶亚基I、组蛋白H3)和33个组内形态特征的约5.5kb序列数据的综合分析，推断了盾片形目三个家族之间的关系。分子数据来自19个组末端，分别代表14个形态种，包括Scutigerina属、Madagassophora属(Scutigerinidae科)、Sphendononema属(Pselliodidae科)、Scutigera属、Thereuopoda属、Thereuonema属、Parascutigera属(Scutigeridae科)。形态分析表明，南部非洲-马达加斯加盾叶蝉科为所有其他盾叶虫目的姊妹种，而新热带-非洲热带盾叶蝉科与盾叶蝉科+盾叶蝉科或盾叶蝉科+盾叶蝉科之间的姐妹群关系通过分子分析和组合分析得到了解决。Scutigeridae和Thereuonminae的单色性在广泛的分析参数范围内是稳定的。海龙亚科由两个稳定的支系组成：一个异足亚科+Parascutigera群，以及一个海龙亚纲，Thereuonema和Thereuopodina群。分子和组合分析将Scutigerina属和形态种Scutigerina weberi解析为副反应，在这两种情况下，马达加斯加分支都排除了来自南部非洲的种群。
Scutigeromorpha ('house centipedes') play a pivotal role in myriapod systematics in being the sister group to all other chilopods, but their internal phylogeny has not been comprehensively appraised since K. W. Verhoeff's morphological investigations a century ago. Relationships between the three families of Scutigeromorpha are inferred based on a combined analysis of approximately 5.5 Kb of sequence data from five molecular markers (complete 18S rRNA, a 2.2- Kb fragment of 28S rRNA, 16S rRNA, cytochrome c oxidase subunit I, histone H3) and 33 ingroup morphological characters. Molecular data are available for 19 ingroup terminals representing 14 morphospecies that include the genera Scutigerina, Madagassophora (family Scutigerinidae), Sphendononema (family Pselliodidae), Scutigera, Thereuopoda, Thereuopodina, Thereuonema, Allothereua and Parascutigera (family Scutigeridae). Morphology resolves the southern African-Malagasy Scutigerinidae as sister to all other Scutigeromorpha, whereas rival sister-group relationships between the Neotropical-Afrotropical Pselliodidae and Scutigerinidae + Scutigeridae or Pselliodidae + Scutigerinidae and Scutigeridae are resolved by the molecular and combined analyses. Monophyly of Scutigeridae and Thereuoneminae are stable across a broad range of analytical parameters. Thereuoneminae is composed of two stable clades: an Allothereua + Parascutigera group, and a grouping of Thereuopoda, Thereuonema and Thereuopodina. Molecular and combined analyses resolve the genus Scutigerina and the morphospecies Scutigerina weberi as paraphyletic, in both cases with a Malagasy clade excluding populations from southern Africa.
