Three coastal species, Aleochara (Emplenota) fucicola Sharp, Atheta (Badura) tokiokai (Sawada) and Cafius histrio (Sharp), were identified and are reported newly from Dokdo island. Their habitus and information about species distribution are provided. Keywords: Coastal Staphylinidae, Dokdo Island, Korea Introduction Dokdo Island as a protected natural area was assigned to no. 336 as a natural monument in 1982. This island is located 87.4 km away from the south east of Ulleungdo Island and consists of two main islands, Dongdo and Seodo. The first report on insect fauna of Dokdo Island was done by Jolivet (1974). After that, several workers reported the survey on insect fauna from Dokdo Island (Lee and Kwon, 1981; Kwon et al., 1996; Lee et al., 2006; Kim and Yeom, 2006; Park et al., 2010). A total of 129 species and 65 families in 11 orders have been recorded in Dokdo Island (Park et al., 2010). But there have been no reports on coastal beetles from Dokdo islands so far. The corresponding author got a chance to survey at Dokdo Island at June, 2012 (Fig. 1) and found three coastal staphylinidae (Aleochara (Emplenota) fucicola Sharp, Atheta (Badura) tokiokai (Sawada) and Cafius histrio (Sharp)) under seaweeds near the dock of Dongdo. We added three coastal species in insect fauna on Dokdo Island. In this survey, the photos of three species are also provided. Korea, this species has habitats in coastal regions of Goseong-gun, Donghae-shi, Samcheok-shi (Gangwondo), Taean-gun (Chungcheongnamdo), Sinan-gun (Jeollanamdo), Pohang-shi (Gyeongsangbukdo), Geoje-shi (Gyeongsangnamdo) and Jejudo Island (Cho and Ahn, 2001; Park and Ahn, 2004). This species was found under seaweeds near the dock of Dondo. Material examined. Korea: Gyeongbuk Province: 29 exs. (HUNHM), Dokdo Is., Ulleung-gun, 27. vi. 2012, Y. B. Cho, under seaweeds. Atheta (Badura) tokiokai (Sawada) This species was reported firstly in Korea by Park et al. (2007) and distributed in Korea and Japan. In Korea, this species has habitats in coastal regions of Jejudo Island (Park et al., 2007). This species was collected under seaweeds near the dock of Dodo. Results Material examined.

This species is distributed in China, Japan and Far East Russia including Korea. In This species was reported firstly by Jeon and Ahn (2002) and distributed in Korea, China and Japan. In Korea, this species has habitats in coastal regions of Goseong-gun, Donghae-shi (Gangwondo), Taean-gun (Chungchengnamdo), Jindo-gun (Jeollanamdo), Yeongdeok-gun (Gyeongsangbukdo), Changwon-shi, Geoje-shi (Gyeongsangnamdo) and Jejudo Island (Jeon and Ahn, 2002). This species was found under seaweeds near the dock of Dongdo. *To whom correspondence should be addressed.

Discussion Two unidentified coastal species, Psammostiba sp. and Myrmecopora sp. of the family Staphylinidae were also found in the same locality of Dokdo Island, but the three species need more time for identification.
