The Western Balkans are an important hotspot of caddisfly diversity in Europe, with several microscale endemics, many of which were discovered during the recent years. The genus Wallengren, 1891 likely originated and diversified in Europe, with the Balkan Peninsula being one of the most important diversity hotspots.
In this paper, we describe the new species sp. n. from Bjeshkët e Nemuna National Park in the Republic of Kosovo. The new species belongs to the species group and is morphologically most similar to Kumanski, 1999, currently known only from Bulgaria and Klapalek, 1902, known from Bosnia and Herzegovina and Serbia. The male of the new species differs from its most similar congeners mainly in exhibiting: (1) elongated subrectangular superior appendages in lateral view; (2) hardly acuminate, almost rounded apex of intermediate appendages; (3) differently shaped, irregular and higher inferior appendages; (4) narrow spinate area, roughly rectangular in dorsal view, slightly wider at the base and (5) different paramere shape and/or spine pattern. The new species also differs by its considerably smaller size and association with open, high altitude eucrenal zones.The uncorrected interspecific pairwise distance between and other species of the species group is on par with those amongst other recognised species in the group, as well as with the yet ambiguously identified taxa from the Sharr, Rila and Bajgorë Mountains.The new species is most probably a microendemic of Bjeshkët e Nemuna, thus highlighting further this area as an important hotspot of caddisfly biodiversity in Europe.
西巴尔干地区是欧洲毛翅目昆虫多样性的重要热点地区，有几种微观尺度的特有物种，其中许多是近年来发现的。1891年的瓦伦格伦属可能起源于欧洲并在欧洲多样化，巴尔干半岛是最重要的多样性热点地区之一。
在本文中，我们描述了来自科索沃共和国比耶什科特·埃·内穆纳国家公园的新物种sp. n.。该新物种属于物种组，在形态上与1999年的库曼斯基种最为相似，目前仅在保加利亚有记录，以及与1902年的克拉帕莱克种相似，后者在波斯尼亚和黑塞哥维那以及塞尔维亚有记录。新物种的雄性与其最相似的同属物种的主要区别在于：（1）侧视图中细长的近矩形上附肢；（2）中间附肢的顶端几乎不尖锐，几乎呈圆形；（3）形状不同、不规则且更高的下附肢；（4）狭窄的具刺区域，背视图中大致呈矩形，基部稍宽；（5）不同的阳茎形状和/或刺的模式。新物种还因其体型明显较小以及与开阔的高海拔真肾区相关联而有所不同。该物种组中该物种与其他物种之间未校正的种间成对距离与该组中其他已确认的物种以及沙尔、里拉和巴伊戈尔山脉中尚未明确鉴定的分类单元之间的距离相当。新物种很可能是比耶什科特·埃·内穆纳的微观特有物种，因此进一步突出了该地区作为欧洲毛翅目昆虫生物多样性重要热点地区的地位。
