The subgenus Amblypteraca Mas-Peinado, Buckley, Ruiz García-París, 2018 of Pimelia Fabricius, 1775, is restricted to the southern Iberian Peninsula and western Maghreb (northern and western Morocco). The distribution of Amblypteraca throughout the African-European edges overlaps largely with the geographic range of the subgenus Amblyptera, which is sister to the clade grouping subgenera Amblypteraca and Ecphoroma Solier, 1836. Delimiting species boundaries in the speciose genus Pimelia is often challenging, and the taxonomic status of some groups within the aforementioned subgenera is still a matter of debate. Here, we aim to stabilize some of the available names in Amblypteraca, and to correct some previous misidentifications. For that purpose, we discuss the composition and taxonomic structure within Amblypteraca by (i) assessing the phylogenetic congruence between mitochondrial and nuclear markers, and (ii) examining external morphological traits in 568 Amblypteraca specimens under the light of the phylogenetic hypotheses proposed here. Based on our results, Amblypteraca consists of three species: P. rotundipennis Kraatz, 1865, P. fairmairii Kraatz, 1865 and P. chrysomeloides Pallas, 1781. Both molecular and morphological data revealed four lineages within P. chrysomeloides: P. chrysomeloides chrysomeloides, distributed on both sides of the Strait of Gibraltar; P. chrysomeloides fornicata Herbst, 1799 from Portugal (Troia region); P. chrysomeloides bathyglypta Antoine, 1949, restricted to a narrow strip between Larache and Arbaoua (northern atlantic Moroccan coast), and P. chrysomeloides subris Koch, 1941 from Kenitra-La Mamora forest (Morocco). We designate a neotype of Tenebrio chrysomeloides Pallas, 1781 and propose the synonymy of P. chrysomeloides (Pallas, 1781) = P. obesa Solier, 1836 syn. n. Pimelia tristis Haag-Rutenberg, 1875, previously misidentified and included in Amblypteraca, is now transferred back to Amblyptera. Further studies with ad hoc sampling designs and analytical tools would be in need to delimit the exact geographic ranges of these taxa, and to analyse the patterns of diversity within and among species and subspecies.
安布利佩特拉亚属（Amblypteraca）Mas-Peinado、Buckley、Ruiz García-París，1818 年，仅限于伊比利亚半岛南部和马格里布西部（摩洛哥北部和西部）。安布利佩特拉亚属在非洲-欧洲边缘的分布与安布利佩特拉亚属（Amblyptera）的地理范围大部分重叠，后者是与 Amblypteraca 和 Ecphoroma Solier，1836 亚属聚类的姐妹群。在特提斯属（Pimelia）中划分物种边界通常具有挑战性，上述亚属内的一些群体的分类地位仍然存在争议。在这里，我们旨在稳定安布利佩特拉亚属中一些可用的名称，并纠正一些先前的错误鉴定。为此，我们通过以下两种方法来评估安布利佩特拉亚属内的组成和分类结构：（i）评估线粒体和核标记之间的系统发育一致性，（ii）根据这里提出的系统发育假设，检查 568 个安布利佩特拉亚属标本的外部形态特征。基于我们的结果，安布利佩特拉亚属由三种物种组成：P. rotundipennis Kraatz，1865，P. fairmairii Kraatz，1865 和 P. chrysomeloides Pallas，1781。分子和形态数据都揭示了 P. chrysomeloides 中的四个谱系：P. chrysomeloides chrysomeloides，分布在直布罗陀海峡两岸；P. chrysomeloides fornicata Herbst，1799 来自葡萄牙（特罗亚地区）；P. chrysomeloides bathyglypta Antoine，1949 仅限于拉腊什和阿尔巴乌阿（摩洛哥北部大西洋海岸）之间的狭窄地带，以及 P. chrysomeloides subris Koch，1941 来自肯尼特拉-拉马莫拉森林（摩洛哥）。我们指定了 Tenebrio chrysomeloides Pallas，1781 的正模标本，并提出了 P. chrysomeloides（Pallas，1781）=P. obesa Solier，1836 syn. n. 的同义词。以前被错误鉴定并归入 Amblypteraca 的 Pimelia tristis Haag-Rutenberg，1875 现在被转回 Amblyptera。需要进一步的专门采样设计和分析工具的研究来限定这些类群的确切地理范围，并分析种内和种间多样性的模式。
