Diagnosis
The apex of each hemitergal lobe of the male tergгum 10 is narrow laterally, bluntly rounded; the apex of the epiproct is narrow, rod-shaped; the lateral stylets are dark, tapering towards the apex and pointed. The supracoxal and submental gills are elongated. The posterior margin of the female subgenital plate is divided by a wide notch into two obliquely cut lobes directed medially backwards (Fig. 6 A-D).
Distribution
Russia, Siberia, Far East (Teslenko and Zhiltzova 2009). Mongolia, North Korea, Japan (DeWalt et al. 2024). The genus Megarcys Klapálek, 1912 and species M. ochracea are recorded for China for the first time.
Notes
Shi (2022) regarded this genus and species as new records from Jiling Province (Mt. Changbai) in his Master’s degree thesis (data are available from CNKI), but it was not published.
