A new species of Protopedaliodes Viloria & Pyrcz, a satyrine butterfly genus endemic to the highest part of the Guyana Shield, P. arekuna Pyrcz & Stachowicz n. sp., is described from the summit area, ca. 2400 m, of Tramen Tepui, an isolated mountain situated on the Venezuela-Guyana border. It is a remarkable finding as it is probably a narrow endemic, and only the fourth known member of the genus. Morphologically it most closely resembles P. kukenani Viloria & Pyrcz from the Roraima-Kukenán twin peaks. COI barcode analysis shows, however, high genetic distances between these two species, 9-10%. Protopedaliodes taxonomy is briefly revised, from the perspective of the monophyly of the genus based on preliminary molecular and morphological comparative data, including the female genitalia described for the first time for P. kukenani and P. ridouti Viloria & Pyrcz.
一种新的 Protopedaliodes Viloria & Pyrcz 物种，一个特有的天社蛾蝴蝶属，位于圭亚那盾的最高部分，P. arekuna Pyrcz & Stachowicz n. sp.，是从 Tramen Tepui 的山顶地区描述的，海拔约 2400 米，这是一个孤立的山脉，位于委内瑞拉和圭亚那的边界上。这是一个显著的发现，因为它可能是一个狭窄的特有种，而且只是该属的第四个已知成员。形态上它最接近来自罗赖马-库肯南双子峰的 P. kukenani Viloria & Pyrcz。然而，COI 条码分析显示，这两个物种之间存在很高的遗传距离，为 9-10%。Protopedaliodes 的分类学从基于初步分子和形态比较数据的属的单系性角度进行了简要修订，包括首次为 P. kukenani 和 P. ridouti Viloria & Pyrcz 描述的雌性生殖器。
