The monophyly of the North and South American endemic subtribe Blapstinina (Tenebrionidae: Opatrini) is tested through phylogenetic analyses using five molecular markers [nuclear ribosomal 28S (28S), cytochrome oxidase subunit II (COII), arginine kinase (ArgK), carbamoyl‐phosphate synthetase domain of rudimentary (CAD), wingless (wg)]. Representatives of several opatrinoid subtribes were taken into consideration, including other geographically overlapping endemic genera, namely Ammodonus, Ephalus and Pseudephalus (all previously considered representatives of Ammobiina). A comparative study of morphology was performed to assess resulting phylogenetic hypotheses. Analyses support the monophyly of Blapstinina; however, they also strongly indicate that Ammodonus should be included within the subtribe. Mecysmus is nested within Blapstinus and therefore, a new synonymy, Blapstinus (= Mecysmus syn.n.), and the following combinations are introduced: Blapstinus advena comb.n., B. angustus comb.r., B. laticollis comb.n., B. parvulus comb.n., B. tenuis comb.n. Morphological analysis showed a close affiliation between Ephalus and Pseudephalus. Based on these results, Pseudephalus is synonymized with Ephalus [Ephalus (= Pseudephalus syn.n.)], and the following combination is introduced: Ephalus brevicornis comb.n. Recovered topologies also strongly support transferring Ephalus stat.n. into Opatrina, making the distribution of Opatrina amphi‐Atlantic.

对 Blapstinina 系统发育的分子见解（鞘翅目：Tenebrionidae：Opatrini）

使用五种分子标记[核糖体 28S (28S)、细胞色素氧化酶亚基 II (COII)、精氨酸激酶 (ArgK)、氨基甲酰磷酸酯，通过系统发育分析测试北美和南美特有亚部落 Blapstinina (Tenebrionidae: Opatrini)基本合成酶域（CAD），无翼（wg）]。考虑了几个类鸦片亚部落的代表，包括其他地理重叠的地方性属，即 Ammodonus、Ephalus 和 Pseudephalus（以前都被认为是 Ammobiina 的代表）。进行了形态学的比较研究以评估由此产生的系统发育假设。分析支持 Blapstinina 的单一性；然而，他们也强烈表明 Ammodonus 应该被包括在亚部落中。Mecysmus 嵌套在 Blapstinus 内，因此，一个新的同义词 Blapstinus (= Mecysmus syn.n.)，并引入了以下组合：Blapstinus advena comb.n.、B. angustus comb.r.、B. laticollis comb.n.、B. parvulus comb.n ., B. tenuis comb.n. 形态学分析显示 Ephalus 和 Pseudephalus 之间有密切的联系。基于这些结果，Pseudephalus 与 Ephalus 同义 [Ephalus (= Pseudephalus syn.n.)]，并引入以下组合：Ephalus brevicornis comb.n。恢复的拓扑也强烈支持传输 Ephalus stat.n。进入 Opatrina，使 Opatrina 两栖大西洋的分布。形态学分析显示 Ephalus 和 Pseudephalus 之间有密切的联系。基于这些结果，Pseudephalus 与 Ephalus 同义 [Ephalus (= Pseudephalus syn.n.)]，并引入以下组合：Ephalus brevicornis comb.n。恢复的拓扑也强烈支持传输 Ephalus stat.n。进入 Opatrina，使 Opatrina 两栖大西洋的分布。形态学分析显示 Ephalus 和 Pseudephalus 之间有密切的联系。基于这些结果，Pseudephalus 与 Ephalus 同义 [Ephalus (= Pseudephalus syn.n.)]，并引入以下组合：Ephalus brevicornis comb.n。恢复的拓扑也强烈支持传输 Ephalus stat.n。进入 Opatrina，使 Opatrina 两栖大西洋的分布。
