Two fungivorous Korean erotylid beetles-Triplax ainonia Lewis, 1887 and Triplax nagaoi Nakane, 1977 in the tribe Tritomini-were recorded for the first time from Korea. All Korean Triplax members are associated with the fruiting bodies of higher fungi and fungus-grown bark. Re-description, key to the species of Korean Triplax, photographs of adults, and line drawings of diagnostic characters and host fungi records are provided.

As XML is a do facto standard for a data exchange language, there have been several researches on efficient processing XML queries. The most important thing to consider when processing XML queries is how efficiently we can process path expressions in queries. Some previous works make results by performing a sequence of join operations on all records corresponding to labels in the path expression. Others works check the existence of paths in the query using an RDBMS's string comparison operator and make results by extracting the records corresponding to the paths. In this paper we suggested a new query planning algorithm based on path containment relationships and two join operators supporting the planning algorithm. The join operators use only the records related to the paths in a query as input data, scan them only once, and generate result data using a pipelining mechanism. By analysis and experiments, we confirmed that our techniques(a new query planning algorithm and two join operators) achieved significantly higher performance than other previous works.

A total of 34 species belonging to 11 families and 21 genera in the Order Mestostigmata are reported from the Korean Peninsula, of which 20/34 species are new for the fauna of the Korean Peninsula (Lasioseius furcisetus Athias-Henriot, 1959, Cheiroseius nepalensis Evans & Hyatt, 1960, Cheiroseius curtipes (Halbert, 1923), Hypoaspis imitatus Reitblat, 1963, Hypoaspis presternalis Willmann, 1949, Hypoaspis kargi Costa, 1968, Pseudoparasitus placentulus (Berlese, 1887), Gamasiphis novipulchellus Ma & Yin, 1998, Parholaspulus bregetovaae Alexandrov, 1965, Parholaspulus paradichaetes Petrova, 1967, Neparholaspis arcuatus Petrova, 1977, Neparholaspus simplex Evans, 1956, Parholaspulus excentricus Petrova, 1967, Gamasholapis asiaticus Petrova, 1967, Veigaia carpillaris Tseng, 1994, Veigaia anmashanensis Tseng, 1994, Leptogamasus bicorniger Witalinski, 1977, Neogamasus insignis (Holzman, 1969), Iphidinychus kakumeiensis Hiramatsu & Hirschmann, 1992, Trigonuropoda sanguinea Hirschmann & Hiramatsu, 1977). A total of 19 of the previously unreported species were collected in soil samples from the Democratic People's Republic of Korea (DPRK), while 13 species were collected from soil samples from the Republic of Korea (ROK). Only two species were found in both the DPRK and the ROK. Illustrations and short descriptions for previously unreported species provided.

Two smittinid species, Pleurocodonellina signata and Smittina torques, are new to Korean bryozoan fauna. Smittina elongata recorded as a new species from Japan is synonymized with Pleurocodonellina signata, and Smittina torques has been reported only from Hew Zealand so far. The genus Pleurocodonellina is recorded in Korean waters for the first time.

Two crangonid shrimps, Paracrangon abei Kubo, 1937 and Pontocaris sibogae (De Man, 1918), collected from the northeastern and southeastern waters of Jeju Island, are newly recorded into the Korean fauna. The former is the second species and the latter is the only species of each genus recorded in Korea. Morphological and distributional accounts of these two species are briefly discussed.

A faunistic list and distribution of aquatic beetles were given with two newly records, Copelatus parallelus Zimmermann, 1920 (family Dytiscidae) and Scirtes sobrinus Lewis, 1895 (family Scirtidae) from Nohwa and Bogil islands in South Korea. As a result, a total of 30 species belonging to 24 genera and eight families were recognized: 12 Dytiscidae species, eight Hydrophilidae species, three Haliplidae species, two Scirtidae species, two Gyrinidae species, one Noteridae species, one Elmidae species, and one Psephenidae species. Composition and habitus photographs of all collected aquatic beetles, habitats, and the diagnostic characters of C. parallelus and S. sobrinus are provided.

Two species of Phycitinae, Rabiria rufimaculella (Yamanaka, 1993) and Copamyntis martimella Kirpichnikova & Yamanaka, 2002, are reported for the first time from Korea. Rabiria rufimaculella can be recognized by having two reddish-yellow and short bands near the postmedial and antemedial line, and by the bifurcate gnathos and the cornutus which is formed by numerous thorn-shaped sclerites in male genitalia. Copamyntis martimella can be distinguished with the congeners by the uniformly distributed setae on the sacculus and the curved aedeagus in male genitalia and the peanut-shaped signum near the middle of the corpus bursae in female genitalia. The adults and genitalia of the species are redescribed and illustrated.
