The Zopheridae Solier consisting of members from three previous families, Zopherinae Solier, Monommatinae Blanchard and Colydiinae Erichson, is considered the taxonomically most challenging group, and comprises more than 1,700 described species worldwide. The members of Zopheridae represent diverse morphological variations, and are difficult to separate morphologically from other tenebrionoid families. Two Zopheridae genera, Colobicus Latreille and Lasconotus Erichson, are identified for the first time in Korea, and two wood-boring species, C. hirtus (Rossi) and L. niponicus (Lewis), are newly reported in the Korean fauna. A key to the genera of Korean Zopheridae, and diagnoses, habitus photographs, and illustrations of diagnostic characters of the two species are provided.

The inhibition of rat lens aldose reductase (AR) in vitro using methanol extracts from Korean folk plants was investigated. Among them, the extracts of Saussurea grandifolia and Rumex crispus showed highest inhibition of AR. $IC_{50}$ values of the extracts from S. grandifolia and R. crispus were demonstrated 0.07 and 0.05 mg/ml, respectively. Korean folk plants such as S. grandifolia and R. crispus has a possibility of new natural resources for the inhibition of AR.

한국산 곡정초과 식물은 Nakai(1911)가 6분류군을 정리한 이래 지금까지 14분류군이 발표된 바 있다. 하지만 분류학적 형질이 총포, 포, 꽃받침, 꽃잎, 종자 등 미세형질에 집중되어 있고, 환경에 따라 식물체의 영양형질 변이가 커서 분류학적으로 어려운 분류군에 속하여 연구가 거의 이루어지지 않았다. 따라서 본 연구는 한반도 곡정초과의 분류학적 연구에 앞서 각 분류군의 과거 표본 기록 및 문헌 자료를 이용해 한반도내 분포 정보를 정리하여 분류군별 분포 범위를 제공하고 그 특성을 연구하고자 한다.

The aim of this research was to investigate the industrial application of Zanthoxylum schinifolium. Antibacterial activities of the n-hexane, methylene chloride (MC), ethyl acetate, and butanol fractions of Z. schinifolium were tested against Escherichia coli, Staphylococcus aureus and Helicobacter pylori. Among the fractions, the n-hexane and MC fractions showed the stronger antibacterial activity against H. pylori, with an inhibition zone greater than 10 mm in disc assays. Further testing of bergapten and lupeol from the MC fraction of Z. schinifolium revealed the antibacterial effects against E. coli, S. aureus and H. pylori, suggesting their potential use as antibacterial agents.

We reported an unrecorded plant species, Galium bungei var. miltorrhizum (Hance) Jeong & Pak in Korea. This species is found in Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongsangbuk-do, and Gyeongsangnam-do. G. bungei var. miltorrhizum is distinguished from related taxa by glabrous stem and glabrous or rarely short papillate mericarps. This taxon was named 'Dung-geun-ne-ip-gal-kwi' in Korean based on shapes of leaves. We provided a description, illustrations, photographs, and a key of related taxa in Korea. And we propose a new combination (Galium bungei var. miltorrhizum).

To search for the aldose reductase (AR) inhibitors from Korean folk plants, the inhibition of rat lens AR in vitro using the methanol (MeOH) extracts from Korean folk plants in Chungcheong Province was investigated. Among Korean folk plants tested, the MeOH extract of Persicaria longiseta showed highest inhibition of AR ($IC_{50}$ value, $5.14{\mu}g/ml$). Consequently, P. longiseta has a possibility of new natural resources for the development of AR inhibitor for the prevention of diabetic complications.

A termitophilous tribe, Rhyparini Schmidt, 1910 of the subfamily Aphodiinae Leach, 1815 (Coleoptera: Scarabaeidae) is newly recorded from Korea for the first time, based on Rhyparus azumai azumai Nakane, 1956. A redescription, illustrations of diagnostic characteristics including male genitalia, and a key to Korean tribe of the subfamily are provided.

Korean species of Leucospis Fabricius (Hymenoptera: Chalcidoidea: Leucospidae) are reviewed, with one newly-recognized species, Leucospis sinensis Walker, 1860. An identification key to the Korean Leucospis species, diagnoses, biological information and photographs of diagnostic characters are provided in the present study.
