本文对隐翅虫属（Empis（Coptophlebia）hyalipennis）类群进行了重新定义、分类和分支系统学分析，并提出了三个新种：土隐翅虫Empis doi，sp. nov.拟棘突舞虻Empis pseudohystricopyga，sp. nov.和拟绒毛突舞虻Empis pseudovillosipes，sp. nov.，描述（分别来自泰国、中国和台湾）。27个成年形态特征的支序分析进行了Empis hyalipennis（Coptophlebia亚属的模式种），和13个新北，东方和古北种假设为密切相关，这导致了一个单一的树的31个步骤（CI = 0.96; RI = 0.98）。单系群的建立是基于雄性下肛的两个形态学特征。根据这些结果和前人对Empis-Coptophlebia复合体在Empis属内亚属的研究，E.（C.）hyalipennis-group似乎在物种上更丰富，表现出更大的形态异质性，并且比预期的分布更广。强烈建议，任何未来的修订亚科Empidinae应适用的名称Coptophlebia只对单系Empis（Coptophlebia）hyalipennis组在这项研究中定义。
The Empis (Coptophlebia) hyalipennis-group is redefined, keyed, cladistically analysed and three new species, Empis doi, sp. nov., Empis pseudohystrichopyga, sp. nov. and Empis pseudovillosipes, sp. nov., are described (from Thailand, China and Taiwan respectively). A cladistic analysis of 27 adult morphological characters was performed for Empis hyalipennis (the type-species of the subgenus Coptophlebia), and 13 Nearctic, Oriental and Palaearctic species hypothesised as being closely related, which resulted in a single tree of 31 steps (CI = 0.96; RI = 0.98). Monophyly of the group was established on the basis of two apomorphic characters of the male hypopygium. Based on these results and previous studies of the Empis-Coptophlebia complex of subgenera within the genus Empis, the E. (C.) hyalipennis-group appears to be much richer in species, exhibit greater morphological heterogeneity and be more widely distributed than expected. It is strongly recommended that any future revision of the subfamily Empidinae should apply the name Coptophlebia only to the monophyletic Empis (Coptophlebia) hyalipennis-group defined in this study.
