ZOOSYSTEMATICA ROSSICA, 22(1): 114–122 25 JUNE 2013 On the systematics and distribution of some poorly known species of Boletina (Diptera: Mycetophilidae) in northern Europe, with the description of a new species К систематике и распространению некоторых малоизвестных видов рода Boletina (Diptera: Mycetophilidae) в северной Европе, с описанием нового вида A.V. POLEVOI А.В. ПОЛЕВОЙ A.V. Polevoi, Forest Research Institute, Russian Academy of Sciences, Pushkinskaya 11, Petrozavodsk 185910, Russia. E-mail: [email protected] A new Palaearctic species, Boletina palmata sp. nov., is described, and three other species, B. kurilensis Zaitzev, B. jamalensis Zaitzev and B. pinusia Maximova, are redescribed. It is dem- onstrated that many specimens from Fennoscandia formerly identified as B. kurilensis belong to B. palmata, while true B. kurilensis occurs only in northern parts of Murmansk Province in Russia, northern Norway and northern Finland. European specimens previously identi- fied as B. jamalensis are proved to belong to B. pinusia, while another closely-related species, B. struthioides Polevoi et Hedmark, is found to be a junior synonym of B. jamalensis. Описан новый для науки вид – Boletina palmata sp. nov., и переописаны три других палеарктических вида: B. kurilensis Zaitzev, B. jamalensis Zaitzev и B. pinusia Maximova. Установлено, что вид B. kurilensis достоверно зарегистрирован только в северных частях Мурманской области, северной Норвегии и северной Финляндии, в то время как многие экземпляры, ранее отнесенные к этому виду, на самом деле принадлежат к описанному здесь виду B. palmata. Европейские экземпляры, ранее отнесённые к виду B. jamalensis, на самом деле идентичны B. pinusia, а еще один близкий вид – B. struthioides Polevoi et Hedmark – является новым младшим синонимом B. jamalensis.
