Abstract

Опубликовано Российским государственным педагогическим университетом им. А. И. Герцена. Открытый доступ на условиях лицензии CC BY-NC 4.0. Аннотация. Anax nigrofasciatus Oguma, 1915 -крупный вид коромысел, распространенный в Восточной, Юго-Восточной и Восточной Азии. 19 июня 2021 года зрелый самец данного вида был пойман Е. Емельяновым в Надеждинском р-не Приморского края в окрестностях СНТ «Садко» на искусственном пожарном водоеме (43.4171 N, 131.9327 E). Это первая находка данного вида в Российской Федерации. Фауна России с учетом новой находки на данный момент составляет 157 видов стрекоз.

Molecular Phylogeny of Holarctic Aeshnidae with a Focus on the West Palaearctic and Some Remarks on Its Genera Worldwide (Aeshnidae, Odonata)

“…Some taxonomic inferences at the species level can be made. Anax julius is well separated from A. parthenope in the COI tree (Figure 3) but not in the ITS tree (Figure 2); the former is in favour of there being different species, as proposed earlier [56][57][58][59][60]62]. The lack of divergence of their ITS region could be ascribed to the above-mentioned putative slower evolution of the ITS region in Aeshnidae.…”

“…str., while the East Asian (including the Far Eastern Russian) specimens represent the taxon A. julius Brauer, 1865. Therefore, we assume the latter as a separate species A. julius, as originally described in detail by Brauer [56] and later again supported by different authors [57][58][59][60].…”

“…Actually, their ITS region differs in just two substitutions in the ITS region. It is noteworthy that Onishko et al[23], who raised the taxon A. soneharai to species level based on external characters, behaviour, sympatric occurrence, and differences in the mitochondrial COII sequences, also sequenced the ITS2 spacer and found it to be identical to A. mixta. We now have sequenced the broader ITS region and found that Aeshna soneharai differs in three nucleotide substitutions from A. mixta.Clade 5 includes Aeshna affinis Vander Linden, 1820 only.…”

Aeshna soneharai Asahina, 1988, stat. rev., bona species – an overlooked member of the European fauna? (Odonata: Aeshnidae)

“…Remarkably, according to observations by VVO, in the southern Far East of Russia several species of Aeshnidae usually form mixed foraging swarms in the evening twilight, which often include also Somatochlora and larger Sympetrum spp. (Onishko & Kosterin 2021), but never A. soneharai . It seems that A. soneharai does not share the swarming behaviour of A. mixta and could be a less active flier.…”

“…The sixth author (AS) attracted attention to occurrence of such individuals in A. mixta from Russia, so this fact was finally mentioned in two most recent books on the European dragonfly fauna (Dijkstra et al . 2020; Onishko & Kosterin 2021).…”
