Eupitheciini is a diverse cosmopolitan tribe of larentiine moths. The structure and musculature of the male terminalia were described in six Palaearctic and Indo-Australian eupitheciine species from the genera Eupithecia Curtis, Gymnoscelis Mabille, and Pasiphila Meyrick (Lepidoptera: Geometridae: Larentiinae). The tergal flexors of the valvae, muscles m4, running to the medial part of the transtilla or to the membrane dorsad of the transtilla are identified as a potential synapomorphy for the tribe Eupitheciini. The tergal extensors of the valvae, muscles m3(2), running deep into the costa valvae is a possible synapomorphy for the genus Gymnoscelis. The genus Pasiphila does not share all eupitheciine characters, with the tergal flexors of the valvae, muscles m4, extending from the dorsal parts of the vinculum. The Eupithecia haworthiata species-group differs from other species-groups by the shape of the uncus and the sternal extensors of the valvae, muscles m8(3), with lateral fibres longer than the medial ones.
Euphithecini 是一个多样化的世界性小卷蛾族。本文描述了来自 Eupithecia Curtis、Gymnoscelis Mabille 和 Pasiphila Meyrick 属的 6 种古北界和印度-澳大利亚的 Euphithecini 物种的雄性外生殖器的结构和肌肉组织（鳞翅目：尺蛾科：Larentiinae）。 瓣片的背侧弯曲肌，m4 肌，向 transtilla 的内侧部分或向 transtilla 背侧的膜运行，被鉴定为 Euphithecini 族的一个潜在的同源特征。瓣片的背侧伸展肌，m3(2)肌，深入到瓣片 costa 内部，是 Gymnoscelis 属的一个可能的同源特征。 Pasiphila 属并不具有所有 Euphithecini 的特征，瓣片的背侧弯曲肌，m4 肌，从连接索的背侧部分延伸。Euphithecia haworthiata 种组与其他种组的区别在于其小钩的形状和瓣片的胸骨伸展肌，m8(3)肌，其侧纤维比内侧纤维长。
