The larva of the Balkan microendemic Isoperla vevcianensis Ikonomov, 1980 (Plecoptera: Perlodidae: Isoperlinae) is described on the basis of larvae associated with adults by means of cox1 sequences similarities. Eggs and everted penis of the male are described for the first time. The larva possessed blunt paraprocts which were previously sharp among Palaearctic larvae of this huge Holarctic and Oriental genus. The commonly pointed paraproct remains as the only distinguishing generic character for the morphologically diverse larvae of Palaearctic Isoperla, but should not be considered as an exclusive character state for the genus. Morphological characters are illustrated in comparison with the sympatric larvae of the Isoperla tripartita species complex.
基于与成虫相关联的 cox1 序列相似性，描述了巴尔干半岛微地方性物种伊科诺莫夫的 Balkan 微地方性的幼体（Plecoptera：Perlodidae：Isoperlinae）。首次描述了卵和雄性的外翻阴茎。幼虫的副突是钝的，而在这个巨大的全北和东洋属的古北地区幼虫中，副突是尖锐的。通常尖锐的副突仍然是形态多样的古北地区的 Isoperla 幼虫的唯一区别属特征，但不应被视为该属的排他性特征状态。形态特征与同域的 Isoperla tripartita 种复合体的幼虫进行了比较说明。
