Abstract: | 120 years ago G.G. Jacobson described two species of leaf beetles from the southern Urals that until recently remained little-known. Chrysolina roddi, previously known only from the foothills of the southern Urals, the low Zhiguli Mountains and the limestone cliýs on the Don River, is recorded from the alpine tundra of the Iremel Massif. The host plant of Ch. roddi in the alpine belt is the small alpine lovage, Pachypleurum simplex (Ligusticum mutellinoides), family Apiaceae. Two species of the subgenus Crositops (Ch. roddi and Ch. kabaki) are presently to be regarded as foothill to alpine taxa. The distribution of Ch. poretzkyi, described from the low-montane part of Bashkortostan, also shows a foothill to alpine disjunction. High mountain populations of Ch. poretzkyi are described as a new subspecies Ch. (Arctolina) poretzkyi olschwangi Mikhailov subsp.n. Revision of the type which has long been considered as being lost confirms the assignment of Ch. poretzkyi to the subgenus Arctolina, in disagreement with its previous placement in the subgenus Pleurosticha. Within Arctolina, the identity of Ch. tundralis and its diýerences from Ch. poretzkyi are discussed. © 2018 University of Toronto Press. 120 лет назад Г. Г. Якобсон описал с Южного Урала два вида жуков-листоедов, Chrysolina roddi и Ch. poretzkyi, которые до недавнего времени оставались мало изученными. Ch. roddi, ранее известный только из предгорий и низкогорий Южного Урала, Поволжья и меловых обрывов на Дону, впервые обнаружен в горных тундрах массива Иремель, где питается на Pachypleurum simplex (Apiaceae). Два вида в подроде Crositops (Ch. roddi и Ch. kabaki) отнесены к предгорно-высокогорным таксонам. Так же как и Ch. poretzkyi, чьи высокогорные популяции выделены в новый подвид Ch. (Arctolina) poretzkyi olschwangi Mikhailov subsp. n. На основании изучения типа, который долгое время считался утерянным, подтверждены принадлежность Ch. poretzkyi к подроду Arctolina и ошибочность отнесения этого таксона к подроду Pleurosticha. В подроде Arctolina обсуждается статус Ch. tundralis и его отличия от Ch. poretzkyi. |
