Exoprosopini is one of the largest tribes of bee flies (Diptera: Bombyliidae). It is divided into 21 genera of which only Ligyra has a cosmopolitan distribution. The genus Ligyra s.l. has 111 species, 20 of which have been recorded in the New World. A cladistic analysis was implemented with aims to establish the phylogenetic relationships of Ligyra species and to test the monophyly of the genus. A matrix of morphological characters available in the literature was used. The cladistic analysis had 97 terminal taxa and 207 morphological characters resulting in 12 maximum parsimonious trees (MPTs). Our investigation shows variations in the phylogenetic status of Exoprosopini genera when compared to the previous hypothesis, especially for Euligyra and Ligyra s.s., and the relationships between Euligyra, Hyperalonia, Ligyra s.s. and Litorhina. Cladistic analysis clarified the phylogenetic relationships within Ligyra s.l. The New World fauna previously included in Ligyra are placed in a new genus, herein erected. A novel monophyletic clade is composed of the genera: Euligyra, Hyperalonia, Ligyra s.s. and Nyia gen. nov. Our results also support the resurrection of Anthrax trifigurata from synonymy with Ligyra cerberus and its new combination with the new erected genus as Nyia trifiguratacomb. nov. & stat. rev.

Ligyra sensu lato(Diptera:Bombyliidae)的爬虫分析,并描述了一个新属

Exoprosopini是最大的蜜蜂蝇部落之一(双翅目:Bombyliidae)。它分为21个属,其中只有Ligyra具有世界性的分布。Ligyra sl属有111种,其中20种已在新世界记录。进行了分类分析,目的是建立天牛属的系统发育关系并测试该属的单性。使用了文献中可用的形态特征矩阵。进化分析具有97个末端分类单元和207个形态特征,产生了12个最大的简约树(MPT)。我们的调查显示,与先前的假设相比,埃索弗罗皮尼属的系统发育状态存在差异,特别是对于欧利古拉而言Ligyra ss,以及EuligyraHyperaloniaLigyra ss之间的关系。和Litorhina。进化论分析阐明了Ligyra sl内的系统发育关系。以前包括在Ligyra中的新世界动物群被放置在这里的一个新属中。一个新的单系进化枝由以下属组成:EuligyraHyperaloniaLigyra ss。和Nyia gen。十一月 我们的研究结果也支持了三足炭疽菌的复活,与小cer蛾(Ligyra cerberus)同义以及与新成立的属Nyia trifigurata梳的新组合年11月。&统计。转速
