They are one of the most numerically dominant arthropod groups in the organic horizons of most soils (Behan-Pelletier, 1999). Punctoribates Berlese, 1908 is a small genus in the family Mycobatidae, having 26 known species distributed worldwide (Bayartogtokh et al., 2000). Adults are small ball-shaped. They are mostly live in the leaf litter and upper soil horizon in terrestrial ecosystem (Rajski, 1968; Seniczak et al., 2006). However, some of them, such as Punctoribates sellnicki Willmann, 1928 live in wet habitats, including Sphagnum and other mosses at the edge of lakes (Seniczak and Seniczak, 2008). Two species of Punctoribates, P. punctum C. L. Koch, 1839 and P. insignis Berlese, 1910 have been recorded so far in Korea. The first species, P. punctum is mostly found in litter and soil of forest (Jung et al., 1998; Park et al., 1998; Lee et al., 2000), but the second species, P. insignis (=Puntctoribates manzanoensis Hammer, 1958) was reported from rice paddy field (Choi, 1995). We found the third species of Punctoribates collected from litter and soil in Seonginbong, Ulleung Island, Korea (Fig. 1). In this work we present a taxonomic diagnosis of the genus and species, and morphological characteristics with detailed illustration. 79 The Korean Society of Applied Entomology (KSAE) retains the exclusive copyright to reproduce and distribute for all KSAE publications.
