Members of Bethylidae are widely distributed from the Tropic to the Subarctic regions around the world. The family contains about 2,216 species worldwide, and the majority of recorded species are found from the tropical regions. From the Oriental region, 368 species of 46 genera in four subfamilies has been recorded up to date. Two species are recognized as new to science and three to the fauna of Cambodia and its adjacent countries in the present study. We provide microphotographs and diagnoses of each species with a general introduction of Cambodian bethylids.

The genus Phymatodes Mulsant (Coleoptera: Cerambycidae) distributes throughout the Holarctic region. Approximately 50 species have been recorded from the world, and four species have been recorded in Korea. In 2010 and 2011, we collected many grape twigs which were severely damaged by unknown larvae of longhorn beetles from Gyeonggi province. They were reared at indoor condition until their emergences in order to see which species inflicted damage on the grape vines. Two species of unknown longhorn beetles were collected. They were identified as Phymatodes jiangi Wang et Zheng and P. zemlinae Plavilstshikov et Anufriev that are new to Korea. The diagnosis and illustrations of P. jiangi and P. zemlinae are provided.

Histeridae is a family of beetles commonly known as clown beetles and hister beetles and approximately 3,900 species in 11 subfamily have been described to date. In Korea, up to days, 53 species of 22 genera of 6 subfamily of them have been recorded. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their elbowed antennae with clubbed ends. Most members of hister beetles are predators and found in most kinds of decaying organic matter, such as droppings, decomposing bodies of animals, compost piles and other decaying plant materials. Some species are also used to control livestock pests that infest dung or to control house flies (Ôhara, 1994). Recently, we have collected several histerid species with Lindgren funner trap for the ecological research on the bark beetles. As a result of this study, we added three newly recorded species, Niponius osorioceps Lewis, 1885, Plegaderus (Plegaderus) marseuli Reitter, 1877 and Trypeticus fagi (Lewis, 1884) to Korean fauna. In this presentation, diagnosis and photographs of characters for each species are presented.

Five erigonine spider species are described with illustrations: a new species, Saitonia pilosus n. sp., and four records new to the Korean spider fauna, Ceratinella brevis (Wider, 1834), Erigone atra Blackwall, 1833, Maso sundevalli (Westring, 1851), and Parasisis amurensis Eskov, 1984. The occurrences of four spider genera, Ceratinella Emerton, 1882, Maso Simon, 1884, Parasisis Eskov, 1984, and Saitonia Eskov, 1992, are also new to Korea.

Two species of the genus Andaspis, Andaspis crawii (Cockerell) and Andaspis kashicola (Takahashi) are newly recorded in the Korean fauna of armored scales (Diaspididae). A key to species of Andaspis, illustrative photographs and information on the distribution and hosts of each species, are also provided to identify the specimens of Andaspis collected in Korea.

The family Bostrichidae contains 9 subfamily and about 580 species. Almost all have adapted to xylophagy, living mainly in sapwood rich in cellulose and many species are considered as serious and onerous technical pests - with increasing export of wooden articles and containers increases also the frequency of introduction of these beetles to various parts of the world, including those of temperate or cold climate (Borowski and Wegrzynowicz, 2007). In Korea, Up to days, 7 species of 5 genera of the family Bostrichidae have been recorded. We added two species, Dinoderus speculifer Lesne, 1895 and Xylothrips pekinensis (Lesne, 1902 - Comb. nov.). And Xylothrips cathaicus Reichardt, 1966 is synonymized with Xylothrips pekineisns (Lesne, 1902 - Syn. nov.). Borowski and Wegrzynowicz (2008) added Xylothrips pekinensis to the Japanese fauna with a photo and mentioned on the possibility of the distribution in the Korean peninsula, but this species had been already recorded to the Japanese fauna by Iwata and Kusakabe (2002).

Three species, Allobethylus tomoae Terayama, Cephalonomia tarsalis (Ashmead), and Laelius yamatonis Terayama of the subfamily Epyrinae are recorded for the first time in Korea. Both sexes of A. tomoae Terayama, C. tarsalis (Ashmead) and female of L. yamatonis Terayama are briefly described with diagnostic morphological illustrations for each species based on the Korean specimens. Male of the genus Allobethylus is discovered for the first time from the word.

Up to days, 31 species of 7 genera of the tribe Xyleborini have been recorded from Korean peninsula. We have collected the bark beetles with Malaise traps from 2007 to 2009 in the central part of the Korean peninsula. As a result of this study, we report 2 species, Xyleborus japonicus Nobuchi, 1981 and X. pelliculosus Eichhoff, 1878, for the first time from Korea with brief descriptions and illustrations of diagnostic characters.

In phyline plant bugs, four genus each with one species are recognized new to Korea: Atractotomoidea castanea Yasunaga, 1999; Moissonia befui Yasunaga, 1999; Monosynamma bohemanni (Fallen, 1829) and Pseudophylus stundjuki (Kulik, 1973). Diagnosis and keys to species are provided with the clear dorsal images and the illustrations of male genitalia. Also the brief biology is discussed.

Aleuroclava aucubae (Kuwana) and Aleuroclava euryae (Kuwana) are newly recorded in the Korean fauna of whiteflies (Aleyrodidae). A key to species of Aleuroclava is also provided with illustrative photographs.

Two species of Miridae, Pachylygus nigrescens (Kerzhner 1977) and Deraeocoris yasunagai Nakatani 1995, are reported for the first time from Korea. The brief information on them is presented with the photos of specimens.

Since Miyamoto & Lee (1966) first recorded three species of Miridae, many species including new species are added to the fauna of Korea by several Korean and foreign taxonomists (Josifov, 1992; Josifov & Kerzhner, 1972; Lee & Kwon, 1991; Lee et al., 1993; Lee et al., 1994). Kwon et al. (2001) collectively arranged the Korean fauna of Miridae into 7 subfamilies, 84 genera, and 209 species, but many species have been believed to remain unrecorded. During recent the recent study of Miridae, we found three unrecorded species, Apolygus roseofemoralis (Yasunaga 1992), Pachylygus nigrescens (Kerzhner 1977), Deraeocoris yasunagai Nakatani 1995. The brief information on them are presented with the photos of specimens. All specimens are deposited in NIAST.
