Beschreibungen/Notizen

• A Palearctic water strider, Gerris (Gerris) lacustris (Linnaeus, 1758) has been known to occur as east as the Russian Far East (Amur, Khabarovsk, Primorskij Kray and Sakhalin), and it is very similar but not closely allied to G. latiabdominis Miyamoto, 1958 (originally described as a subspecies of lacustris). Recently, we have recognized the water strider G. lacustris from central and eastern Hokkaido for the first time. In any localities, both G. lacustris and G. latiabdominis are observed to occupy a same marshy pond.
