Material examined: 1 male paratype ( IBSS) from town Maram (20 km NE Phjŏngjang), District Jongsŏng, Prov. Phjŏngjang­si, North Korea, collected 29 May 1965 by M.Mroczkowski et A.Riedel; 1 male, 1 female (ChNU) from Inje, Dogaetang, Gangwondo, South Korea, collected 5 September1998 by K.­Y. Lim; 1male, (ChNU) from litter, Quercus forest, Mt. Jiri, South Korea, collected 23 April 2000 by K.­Y. Lim.

Remarks. Originally described from North Korea ( Mikhaljova et al., 2000), and previously known only from there, hence Angarozonium munsunum is new for the fauna of the South Korea.

This species is the only representative of the genus currently known to occur in Korea. The records of A. bonum ( Mikhaljova, 1979) in North Korea ( Golovatch, 1980, 1981; Mikhaljova & Kim, 1993; Lim, 2001) appear to be misidentifications; these mistakes were revealed by a restudy ( Mikhaljova, 2002) of the formerly misidentified male from North Korea. The identity of the localities proves that Lim et al. (1992) misidentified A. munsunum specimens from Mt. Chiri, South Korea as belonging to A. bonum .

A. munsunum differs from congeners by the inner coxal process of the anterior gonopods being closely adjacent to and finally fusing with the telopodite as well as by a coaxially placed telopodite of the anterior gonopods and by the apex of distal podomere of anterior gonopod telopodite devoid of setae or any processes.

The above material appears to show some variation in gonopod structure. Thus, the anterior gonopod telopodites are placed parallel to main axis in the paratype, being placed under a small angle to the main axis in South Korean males. The size of the anterior gonopod sternite varies as well.

Distribution. North and South Korea.
