隐翅虫亚科是隐翅虫中最具多样性的亚科之一，但其进化历史仍然知之甚少。这是由于系统发育研究的数量有限，这些研究要么在较浅的分类学水平上寻求答案，要么包括有限的分类取样。特别有问题的是罕见的新热带族droxystini的位置，形态上最令人困惑的群体之一。该类群在亚科的系统发育位置从未被了解，尽管其在分类中的地位已经被移动了两次。我们组装的分子和形态数据矩阵采样从所有目前公认的亚族，包括两个属的Droxystini，并使用这些数据来估计系统发育关系，使用贝叶斯推断。共分析了76个类群的123个形态特征和4,631 bp的核（28 S、TP、Wg、CADA、CADC、ArgK）和线粒体（COI）序列。目前的部落Aproxystini被解决为一个单门内的部落Lathrobiini作为姐妹属Pseudolathra，并在一起，他们是姐妹所谓的'Medonina和有关类群'林地。根据这些结果，我们将阿屈斯汀族降级回亚部落级别，恢复阿屈斯汀族的地位，现在有了一个已知的姐妹群。这是迄今为止该亚科中最大的一个，并为建立该类群的自然分类奠定了基础。
Paederinae is one of the most diverse subfamilies among rove beetles, yet their evolutionary history remains poorly understood. This is attributed to the limited number of phylogenetic studies, which either sought answers at a shallower taxonomic level or included limited taxon sampling. Especially problematic is the position of the rare Neotropical tribe Cylindroxystini, morphologically one of the most puzzling groups of Paederinae. The phylogenetic position of this group within Paederinae was never understood, though its rank in the classification has already been shifted twice. We assembled molecular and morphological data matrices sampled from all currently recognized Paederinae subtribes, including both genera of Cylindroxystini, and used these data to estimate phylogenetic relationships using Bayesian inference. A total of 123 morphological characters and 4,631 bp of nuclear (28S, TP, Wg, CADA, CADC, ArgK) and mitochondrial (COI) sequences were analyzed for 76 taxa. The current tribe Cylindroxystini was resolved as a monophylum within the tribe Lathrobiini as sister to the genus Pseudolathra, and together they are sister to the so-called 'Medonina and allied taxa' Glade. Based on these results, we downgraded Cylindroxystini back to the subtribal level, Cylindroxystina status reinstated, now with a known sister group. The resulting phylogeny is the largest of the subfamily Paederinae to date and lays the foundation for establishing a natural classification of the group.
