New records of Pseudogaurotina magnifica (Plavilstshikov, 1958) (Coleoptera: Cerambycidae: Lepturinae: Rhagiini) in Primorskiy and Khabarovsk regions (Russia), with the description of a previously unknown male

Abstract. New records of one of the rarest longicorn beetle species of the Russian fauna, Pseudogaurotina magnifica (Plavilstshikov, 1958), in Primorskiy and Khabarovsk regions are presented. It was previously known only from three females, including two type specimens. A description of the male of this species that strongly differs from the female by the colouration of the legs and venter is given for the first time. The distribution area of P. magnifica covers at least more than half of the territory of Sikhote-Alin Mountain Range in the meridional direction, from the vicinity of Dalnegorsk in the south to the vicinity of Tumnin village in the north. The locality of the paratype of this species is established (Primorskiy Region, Sikhote-Alin Reserve, Serebryanka River basin, Serebryanyy Stream), while the locality of specimen in question, given by M.L. Danilevsky (Primorskiy Region, Serebryanyy Stream, about 60  km north of Nakhodka), is recognized as fictitious. The type locality of Gaurotina sichotensis Danilevsky, 1988 is designated (Primorskiy Region, eastern macroslope of the Sikhote-Alin, Kema River floodplain between the Gorelaya Polyana and the Yasnaya Polyana natural boundaries), whereas the type locality of this species indicated by M.L. Danilevsky (Primorskiy Region, western slope of the Sikhote-Alin) turned out to be fictitious as well. One of the two collected males of Pseudogaurotina magnifica in the Sikhote-Alin Reserve was found when shaking off a honeysuckle bush (Lonicera sp.). Based on this finding and some other data, it is assumed that this species is ecologically related to honeysuckle like the Carpathian endemic P. excellens (Brancsik, 1874). A strong morphological similarity between males of P. magnifica and males of Gaurotina sichotensis, a species that also inhabits the Sikhote-Alin Mountains, is noted. This fact seems to the authors very curious, although it is not excluded that G. sichotensis may be a synonym of P. magnifica.
