The Seoul forest of urban forest park is provide places for relaxation and feeling naturally use inside the city. This study was conducted for investigating diversity of soil microarthropods for Bioblitz. Samples were collected from rose of Sharon in soil. This species was identified as N. harrowi (Collyer), described originally from New Zealand and Austrilia. This is the new record of N. harrowi in Korea. The morphological features of these two species are closely related to each other (N. makuwa (Ehara) and N. harrowi (Collyer)). So, we compared features of this species. Dorsal setae of N. harrowi are generally longer than in N. makuwa. Two posterior seta (Z4, Z5) of N. harrowi are much shorter than in the N. makuwa. In addition, there are some differences in the shape of the spermatheca, the forked atrium is larger in N. makuwa than in the N. harrowi.
