Abstract

We present the most comprehensive molecular phylogeny of scuttle flies (Diptera: Phoridae) to date based on seven genetic loci—four protein‐coding genes: arginine kinase (AK), carbamoylphosphate synthase 2 domain of CAD (rudimentary; CAD2), cytochrome oxidase I (CO1), NADH1 dehydrogenase (ND1) and three ribosomal DNAs: 12S, 18S and 28S. Our analyses include 122 species including nine outgroup taxa and 113 phorids (representing 61 genera). Phylogenetic relationships based on the approximately 5.3 kb of sequence data were inferred by maximum likelihood and Bayesian methods. Results are broadly congruent with recent morphological phylogenies of the group, with some significant exceptions. Our data support the monophyletic Sciadocerinae as sister to the remainder of the family. However, we found Ctenopleuriphora Liu to be sister to Phorinae with low support, and subfamilies Chonocephalinae and Termitoxeniinae are placed deep within Phorinae, and their monophyly is not consistently recovered. Our dating analyses indicate a lower Cretaceous origin of Phoridae at 120.8 Ma (125.4–111.2 Ma).

锹形蝇（双翅目：蝇科）的分子系统进化揭示了与形态学结果的广泛一致性和引人入胜的差异

我们基于七个基因位点--四个蛋白质编码基因：精氨酸激酶（AK）、CAD 的氨基甲酰磷酸合成酶 2 结构域（原始；CAD2）、细胞色素氧化酶 I（CO1）、NADH1 脱氢酶（ND1）和三个核糖体 DNA，提出了迄今为止最全面的鞘蝇类（双翅目：鞘蝇科）分子系统发育：12S、18S 和 28S。我们的分析包括 122 个物种，其中包括 9 个外群类群和 113 个噬菌体（代表 61 个属）。通过最大似然法和贝叶斯法，根据约 5.3 kb 的序列数据推断出了系统发生关系。结果与该类群最近的形态学系统发育大致吻合，但也有一些明显的例外。我们的数据支持单系的 Sciadocerinae 成为该科其余部分的姊妹。然而，我们发现 Ctenopleuriphora Liu 与 Phorinae 是姊妹科，但支持率较低，Chonocephalinae 亚科和 Termitoxeniinae 亚科被置于 Phorinae 的深处，它们的单系性没有得到一致的恢复。我们的年代分析表明，Phoridae起源于下白垩世，时间为 120.8 Ma (125.4-111.2 Ma)。
