Abstract

The collection of adults, mature male pupae, and the absence of confusing species at the sampling sites located in the Cevennes and French Alps enabled descriptions of the hitherto unknown larvae of Plectrocnemia cevennensis Coppa 2011 and P. praestans McLachlan 1884 (Trichoptera, Polycentropodidae). We present information on the morphology of the larvae and illustrate the most important diagnostic features. In the context of the larval key to European Plectrocnemia species by Waringer Graf (2020), P. cevennensis keys together with P. scruposa McLachlan 1880, whereas P. praestans keys with P. conspersa (Curtis 1834). These two species pairs are morphologically very close; P. cevennensis and P. scruposa can be separated by the numbers of secondary setae on the last abdominal sternum, but the separation of P. praestans and P. conspersa is not always possible.

摘要

在塞文山脉和法国阿尔卑斯山的采样点采集到的成年雄性蛹和没有混淆物种，这使得我们能够描述 hitherto 未知的 Plectrocnemia cevennensis Coppa 2011 和 P. praestans McLachlan 1884（蜉蝣目，Polycentropodidae）幼虫。我们提供了幼虫形态学信息，并说明了最重要的诊断特征。在 Waringer Graf（2020）的欧洲 Plectrocnemia 物种幼虫关键中，P. cevennensis 与 P. scruposa McLachlan 1880 一起鉴定，而 P. praestans 与 P. conspersa（Curtis 1834）一起鉴定。这两对物种在形态上非常接近；P. cevennensis 和 P. scruposa 可以通过最后一个腹部胸板上的次生刚毛数量来区分，但 P. praestans 和 P. conspersa 的区分并不总是可能的。
