Pterocallini is one of the largest tribes within Ulidiidae, with more than 130 species described in 27 genera. The great majority of Pterocallini species are endemic to the Neotropics. They are characterised by the wings pictured with dark patterns, but some species of Pterocallini also are recognised by some extraordinary forms of sexual dimorphism, such as stalked eyes. In this study, we propose the first hypothesis of internal relationship of the tribe and tested the monophyly of some of the genera of Pterocallini. Our matrix consisted of 86 morphological characters and 58 terminal taxa that were sampled from 21 genera of Pterocallini and four outgroup genera. We performed a parsimony analysis under implied weighting of the characters, which resulted in one maximum parsimonious tree. Our findings corroborate some of the preceding non-phylogenetic hypotheses of sister relationships within Pterocallini. Our analysis supported the monophyly of the genera Aciuroides, Lathrostigma, Neoacanthoneura, Neomyennis, Plagiocephalus, Pseudopterocalla, Rhyparella, Terpnomyia and Xanthacrona but did not support natural groupings of Apterocerina, Dasymetopa, Megalaemyia, Paragorgopis, Pterocalla and Pterocerina species.

从形态学分析推断出翼缘P翅蝇（双翅目：Ulidiidae）的系统发育关系。

Pterocallini 是 Ulidiidae 中最大的部落之一，在 27 个属中描述了 130 多个物种。大多数 Pterocallini 物种是新热带地区特有的。它们的特征是翅膀上绘有深色图案，但一些 Pterocallini 物种也被一些非凡的两性异形形式所识别，例如被跟踪的眼睛。在这项研究中，我们提出了部落内部关系的第一个假设，并测试了一些 Pterocallini 属的单系性。我们的矩阵由 86 个形态特征和 58 个末端分类群组成，它们是从 Pterocallini 的 21 个属和四个外群属中采样的。我们在字符的隐含权重下进行了简约分析，这导致了一个最大简约树。我们的发现证实了之前关于 Pterocallini 内姐妹关系的一些非系统发育假设。我们的分析支持该属的单一性Aciuroides，Lathrostigma，Neoacanthoneura，Neomyennis，Plagiocephalus，Pseudopterocalla，Rhyparella，Terpnomyia和Xanthacrona但不支持的自然分组Apterocerina，Dasymetopa，Megalaemyia，Paragorgopis，Pterocalla和Pterocerina种。
