Abstract

Representatives of the cockroach superfamily Corydioidea are less sampled than members of the two other cockroach superfamilies (Blaberoidea and Blattoidea) due to the difficulty of collecting them in the field, accentuated by a general lack of knowledge on their biology. Their evolutionary relationships have not yet been investigated with a relevant sampling and are therefore poorly known. Here, we assess the phylogenetic relationships of 35 Corydioidea species with mitochondrial genomes and two nuclear gene fragments. Our sampling for Corydiidae comprises Corydiinae and Euthyrrhaphinae representatives, whereas our sampling for the remaining Corydioidea includes species belonging to genera Beybienkonus Qiu, Wang and Che, Compsodes Hebard, Ctenoneura Hanitsch and Nocticola Bolívar. We further infer their divergence times with molecular dating analyses relying on five fossil calibrations. We also carry out reconstructions of ancestral character states for 11 phenotypic and one biological traits. Our results recover two major Corydioidea clades, one consisting solely of Corydiidae (except Latindiinae) and the other of all remaining Corydioidea taxa. Based on the results of phylogenetic analyses, an updated classification of extant Corydioidea is proposed, where Latindiinae Handlirsch stat.rev. and Ctenoneurinae Qiu and Che, subfam.nov. are assigned to the family Nocticolidae Bolívar sensu nov. A new genus Pseudoeupolyphaga Qiu and Che, gen.nov. is also established within Corydiinae. Both the origin of crown Corydioidea and the divergence of the two major lineages are estimated to have occurred during the Triassic–Jurassic boundary. Ancestral character state reconstruction analyses also suggest an adaptive relationship between phenotypic characteristics and habitat preferences.

蝶形目(双翅目:蜚蠊科)的系统发育重建为 Latindiinae 的定位提供了新的见解,并支持了 Ctenoneurinae 新亚科的提议
与其他两个蟑螂超科(Blaberoidea 和 Blattoidea)的成员相比,蜚蠊超科(Corydioidea)的代表蟑螂取样较少,这是因为在野外采集它们很困难,而且对它们的生物学知识普遍缺乏了解。它们的进化关系尚未通过相关取样进行研究,因此知之甚少。在此,我们利用线粒体基因组和两个核基因片段评估了 35 个堇菜科物种的系统发育关系。我们对堇菜科(Corydiidae)的取样包括堇菜科(Corydiinae)和堇菜属(Euthyrrhaphinae)的代表物种,而我们对其余堇菜科(Corydioidea)的取样包括属于Beybienkonus Qiu、Wang和Che属,Compsodes Hebard属,Ctenoneura Hanitsch属和Nocticola Bolívar属的物种。我们根据五种化石的校准,通过分子测年分析进一步推断了它们的分化时间。我们还重建了 11 种表型特征和 1 种生物特征的祖先特征状态。我们的研究结果发现了两个主要的 Corydioidea 支系,一个支系仅由 Corydiidae(Latindiinae 除外)组成,另一个支系则由所有剩余的 Corydioidea 类群组成。根据系统发育分析的结果,提出了现存 Corydioidea 的最新分类,其中 Latindiinae Handlirsch stat.rev. 和 Ctenoneurinae Qiu and Che, subfam.nov. 被归入 Nocticolidae Bolívar sensu nov.科。新属 Pseudoeupolyphaga Qiu and Che,gen.nov. 也在 Corydiinae 内建立。据估计,冠毛目(Corydioidea)的起源和两大支系的分化都发生在三叠纪-侏罗纪边界。祖先特征状态重建分析也表明了表型特征与生境偏好之间的适应关系。
