Anax nigrofasciatus Oguma, 1915: 121 View in CoL . Type locality: Okayama; Kyoto , Totomi; Tokyo
[ Japan].
MATERIAL EXAMINED. Russia: Primorskii krai, Khasanskii district , Gamov Peninsula, Vitjaz settl., 42º35'56"N, 131º11'13"E, 14–16.VII 2021, 3♂, leg. Yu. Chistyakov GoogleMaps (2♂
deposited in FCBV; 1♂ was taken alive from a spiderweb and then released).
HABITAT. Collecting site (Fig. 2) is located about 150 m from the sea shore in a boggy valley with sparse spreading trees of Salix caprea , S. udensis , Alnus japonica , A. hirsuta and
Fraxinus mandshurica where there are two rather small, no more than 200 square meters each, 20-year-old artificial ponds. The depth of the ponds is about 2 meters or even less; their banks are occupied by the same vegetation that used to grow in this valley: Calamagrostis langsdorffii , C. extremiorientalis, Lithrum salicaria, Poa pratensis, Carex maackii, C. rhyn-
chophysa, Juncus decipiens , Scirpus asiaticus and others. Shallow areas of the ponds are overgrown with Calla palustris , Phragmites communis and Typha orientalis . The water surface is mostly covered by Nymphoides peltatum .

DISTRIBUTION. The species occurs in Japan except Hokkaido (Sugimura et al., 2001),
in South Korea (Lee, 2001), North, East, South, and Central China (Hua, 2000), Hong Kong
(Reels, 2019), Taiwan (Lieftinck et al., 1984; Wang, 2000), and Vietnam (Cuong & Hoa,
2007). The record from the Philippines is considered doubtful (Wilson, 2009).
COMMENTS. A. nigrofasciatus is easily distinguished from its congeners distributed in Russia by the presence of distinct, bright black T-shaped mark on the horizontal part of frons, by black thoracic sutures on green thorax and black abdomen with 2 pairs of blue
(green in females) lateral spots on tergites 3-10.
