Barcoding aphids (Hemiptera: Aphididae) of the Korean Peninsula: updating the global data set

DNA barcode (mitochondrial COI) sequences are provided for species identification of aphids from the Korean Peninsula. Most (98%) of the 154 species had distinct COI sequences (average 0.05% intraspecific pairwise divergence) relative to the degree of sequence divergence among species (average value 5.84%). For species in common with other regions, barcodes for Korean samples fell near or within known levels of variation. Based on these results, we conclude that DNA barcodes can provide an effective tool for identifying aphid species in such applications as pest management, monitoring and plant quarantine.

Seasonal changes of functional groups in coleopteran communities in pine forests

Fauna assemblages reflect their habitat relating to ecological function in an ecosystem. The functional groups are concerned with how a resource is processed by different species to provide a specific ecosystem service or function. We elucidated seasonal changes of coleopteran functional groups in forests, and evaluated their ecological roles related to available food resources. Coleopteran communities were collected weekly or biweekly using Malaise traps at nine study sites in Japanese red pine forests in Korea from late June to September 2005. Compositions of the functional groups were compared at the different sites and at sampling times with respect to taxa richness and abundance. Cluster analysis and non-metric multidimensional scaling were used to characterize spatial and temporal changes of functional groups. Herbivores and dead/live wood feeders regulating primary production in the pine forests were the dominant coleopteran groups in July, followed by detritivores and predators that dominated from July to August, resulting from the accumulation of detritus. Then, fungivores became dominant due to increased fungal biomass in the forest. Seasonal changes of coleopteran functional groups shifted from regulators of primary production to regulators of decomposition, reflecting their available food resources. In addition, abundance of detritivores and predators were dependent on total abundance of coleopterans, suggesting that these two groups reflect their habitat condition.

Cephalonomia gallicola (Hymenoptera: Bethylidae), New to Korea, an Ectoparasitoid of the Cigarette Beetle, Lasioderma serricorne (Coleoptera: Anobiidae)

Abstract An ectoparasitoid natural enemy, Cephalonomia gallicola (Ashmead 1887) (Hymenoptera: Bethylidae) was found in the mass rearing colonies of cigarette beetle, Lasioderma serricorne (Fabricius 1792) (Coleoptera: Anobiidae), under laboratory condition. As the first record in Korea, the description of the apterous female is provided for the macerated microslide specimens, with the detail illustration for the taxonomic characteristics and the biometric data.

A Review of Host Plants of Cerambycidae (Coleoptera: Chrysomeloidea) with new Host Records for Fourteen Cerambycids, Including the Asian Longhorn Beetle (Anoplophora glabripennis Motschulsky), in Korea

A revised checklist of host plants for 181 species belonging to 103 genera in six subfamilies of Cerambycidae (Coleoptera: Chrysomeloidea) in Korea is provided on the basis of the results of field surveys and literature review. A total of 14 new cerambycid-host associations are confirmed and the Manchurian striped maple, Acer tegmentosum Maxim. (Aceraceae), is listed as a new host of the Asian longhorn beetle, Anoplophora glabripennis (Motschulsky). The names of more than 170 host plants species belonging to 107 genera in 44 families are compiled. Among them, four families (Ulmaceae, Pinaceae, Fagaceae and Betulaceae) are confirmed as the main host families (more than 23%) of most of the cerambycid species. All invalid scientific names and Korean names of plants and cerambycids in the previous literature are corrected in the present paper.

Five new species of Disepyris Kieffer, 1905 (Hymenoptera: Bethylidae), with emended generic diagnosis.

Five new species of Disepyris Kieffer (Hymenoptera: Bethylidae) are described and illustrated: D. kenyaensis Lim & Azevedo, sp. nov. (Kenya), D. fessus Lim & Azevedo, sp. nov., D. mongoliaensis Lim & Azevedo, sp. nov., D. prolatatus Lim & Azevedo, sp. nov. (Mongolia), D. niveus Lim & Azevedo, sp. nov.

Legs polished without sculpture, appressed pubescence absent; mesotibia with sparse, short spines on apical half; hind basitarsus with one row of comb ventrally.
