其他摘要：Root vole consists of 30 subspecies distributed in Holarctic. The subspecies Pannonian root vole (Microtus oeconomus mehelyi Éhik, 1928) is one of the rarest, since it occurs only in isolated areas of Central Europe. This paper brings together some early facts about the subspecies assembled from historical papers, correspondence, and information from the museum collections with the aim to identify and assign the museum specimens to the records. The oldest known specimens, collected by the taxidermist Károly Kunszt at the end of 19th century, come from the vicinity of Šamorín. The exact trapping locality of at least some of them is the Danubian island Helena at the river kilometer 1845. The oldest specimen probably comes from the year 1892; however, the exact date and locality of collection of this specimen have not been stated. The type set originally used to describe the mehelyii subspecies comprised 15 specimens also coming from K. Kunszt. Four of them (1 holotype and 3 paratypes) were identified; the rest of the paratype set could not be identified unambiguously.
