In the Swiss Jura adults of and unknown Drusinae larvae which could not be identified with existing keys were sampled. Based on ripe pupae, the unknown larvae were identified as . The association was confirmed by specimen rearing in aquaria. Based on morphology, larvae of key out together with in existing keys. is separated from the latter species by the shape of the anteromedian metanotal sclerites which are broadly triangular, whereas in the sclerites are almost parallel-sided, resembling a stretched rectangle. In addition, the two species are geographically well separated: is restricted to the confines of Croatia and Slovenia, whereas is only present in Switzerland and eastern France. With this present paper, all Central European Drusinae species except McL, 1901 (France, Switzerland) and Malicky, 1981, an endemic from the Saualpe (Carinthia, Austria), are known in the larval stage.
在瑞士汝拉地区,采集了一些无法用现有检索表鉴定的成年德鲁西纳以及未知的幼虫样本。基于成熟蛹,这些未知幼虫被鉴定为[具体物种名称未给出]。通过在水族箱中饲养标本,证实了这种关联。基于形态学,在现有检索表中,[该物种名称未给出]的幼虫与[另一物种名称未给出]归为一类。[该物种名称未给出]与后一种物种的区别在于中胸背板前中位骨片的形状,前者呈宽三角形,而在[另一物种名称未给出]中骨片几乎平行边,类似拉长的矩形。此外,这两个物种在地理上分隔良好:[该物种名称未给出]局限于克罗地亚和斯洛文尼亚的边界,而[另一物种名称未给出]仅存在于瑞士和法国东部。通过本文,除了1901年的[物种名称未给出](法国、瑞士)和1981年的[物种名称未给出](奥地利卡林西亚州绍阿尔佩的特有种)外,所有中欧德鲁西纳物种的幼虫阶段均已为人所知。
