Remarks: Originally described from North Korea ( VERHOEFF, 1937), this species is widespread all over Korea as well as in the adjacent parts of Primorsky kray (= Maritime Prov.), Russian Far East ( MIKHALJOVA 1998, MIKHALJOVA & LIM 2000), and South Japan. It is a senior subjective synonym of both Epanerchodus dichotomus TAKAKUWA, 1954 and E. bifidus TAKAKUWA, 1954 ( MIKHALJOVA & LIM 2002).

Epanerchodus beroni MIKHALJOVA et KIM, 1993 – 1 m – North Korea, Prov. North Pyongan, Mts. Myohyang-san, Isonnam valley , No. 1393., 24.May 1991., leg. RONKAY L. & VOJNITS. A.

Remarks: The species is known solely from its terra typica, i.e. North Korea ( MIKHALJOVA & Kim 1993). There is no reliable information concerning the find of this species in South Korea. The dentiform caudal process of the gonopod femorite represents the sole difference between this specimen and the holotype, but this variation is obviously infraspecific.

Epanerchodus polymorphus MIKHALJOVA et GOLOVATCH, 1981 – 1 m – Russia, Far East, Primorsky kray, Ussuriyskiy Nature Reserve , hills on the SW part of the territory, 300 m a.s.l., No. 18., 6.July 1990., leg. SZIRÁKI GY.

Remarks: Originally described from the southern part of the Russian Far East (Primorsky kray = Maritime Prov.) ( MIKHALJOVA & GOLOVATCH 1981), this species appears to be quite widespread there and has been recorded in North Korea as well (MIKHALJOVA et al. 2000). The species is polymorphic with two distinct male morphs (forma digitata and forma simplificata), and a continuous variation range of females, all coexisting.
