This study aims to rectify the taxonomy of Pholidopterini (Orthoptera, Tettigoniidae, Tettigoniinae) using a phylogenetic approach. To this end, DNA sequences of three mitochondrial and two nuclear genes were produced and analysed. Reconstructed phylogenetic trees were consistent with the limits of the tribe and internal generic clades. However, the relationship among genera could not be resolved. Based on these trees and previous publications, we draw the following conclusions. Pholidopterini is monophyletic and consists of nine internal clades corresponding to generic level taxa. Pholidoptera, Eupholidoptera, Parapholidoptera, Apholidoptera, Uvarovistia and Exopholidoptera were previously given in the tribe, and Psorodonotus is transferred from Platycleidini. Aparapholidoptera Çıplak gen. n. and Spinopholidoptera Çıplak gen.n. are two new genera in the tribe. Additionally, the macro‐evolutionary pattern of the tribe was evaluated by correlating the tempo of radiation and the homology/homoplasy status of morphological characters used in generic descriptions/diagnoses. Results indicated that rapid radiation periods prior to achievement of lineage monophyly may leave their signature as instability or polytomy in present phylogenetic reconstruction, and cause the evolution of homoplasic characters and reticulate character sharing among the units in a lineage. This pattern may explain why genera in the Pholidopterini are definable by non‐unique character combinations.

回顾Pholidopterini(直翅目,Tettigoniidae):快速辐射会引起同质性和系统发育不稳定性

这项研究的目的是通过系统进化方法对凤尾蝶科(直翅目,T蝶科,T蝶科)进行分类。为此,产生并分析了三个线粒体和两个核基因的DNA序列。重建的系统发育树与部落和内部普通进化枝的限制一致。但是,属之间的关系无法解决。基于这些树和以前的出版物,我们得出以下结论。hol翅目是单生的,由九个内部进化枝组成,对应于一般级别的分类群。PholidopteraEupholidopteraParapholidopteraApholidoptera,UvarovistiaExopholidoptera以前在部落中被给予,而假单胞菌则从Platycleidini转移而来。伞形虫Çıplakgen。。和鞘翅目Çıplakgen.n. 是部落中的两个新属。此外,通过将辐射的速度与一般描述/诊断中使用的形态特征的同源性/同质性状态相关联,来评估部落的宏观进化模式。结果表明,在实现谱系单亲之前的快速辐射期可能会在当前的系统发育重建中留下其不稳定或多义性的特征,并导致谱系内同质性状的进化和网状性状的共享。这种模式可以解释为什么Popteridopterini中的属可以通过非唯一字符组合来定义。
