Anastrangalia dubia reyi, widely distributed but in the Central Europe not so abundant submontane/montane taxon, known for long time under name Leptura inexpectata Jansson & Sjöberg, 1928, has been firstly recorded by Claudius Rey in 1885 from Isère region (France) as Leptura dubia race ochracea [❖]. Due to the preoccupation of the name ochracea, Lucas F. Heyden proposed the species name reyi for this taxon in 1889 [✮]. However, this brief mention was forgotten and thus there was a new description of the taxon from Sweden under the name Leptura inexpectata by Anton Jansson and Oscar Sjöberg in 1928 [✳]. In the second half of the 20th century, the mistake was corrected and the name reyi became commonly used.

According to a recent detail DNA and morphological (male genitalia) study by Andrey Zamoroka and his colleagues, A. reyi is only a subspecies of A. dubia [✧]. However, the presented data and the conclusions drawn from them are not entirely convincing, so the position of the taxon reyi remains, in our opinion, still open...

A. dubia reyi larvae develop and pupate in the rotten wood of Pinaceae (Abies, Picea, Pinus). Life cycle 2 years. Adults, active from June to August, are diurnal and anthophilous [✱][❂].

Body length:	♂♂ 7.5 - 12.5 mm / ♀♀ 8.7 - 13.5 mm
Life cycle:	2 years
Adults in:	June - August
Host plant:	conifers (Abies, Picea, Pinus)
Distribution:	Austria, Belarus, Czechia, Estonia, Finland, Grance, Germany, Hungary, Italy, Latvia, Lithuania, Norway, Poland, Russia, Romania, Slovakia, Spain, Sweden, Switzerland, Ukraine, Kazakhstan

The depicted mounted female beetle (14 mm) was collected in Pavlovskaya Sloboda (Павловская Слобода) village environs (Istrinsky district, Moscow oblast, Central Federal District, Russia) on June 8-20, 2014.

Probably the best morphological feature for distinguishing subspecies dubia dubia and dubia reyi is the shape of the head:

• A. dubia reyi - temples short, not cheek-like, not dilated behind
• A. dubia dubia - temples long, strongly cheek-like, dilated behind
