Callosobruchus chinensis (Coleoptera: Bruchidae) is the main pest of mungbean (Vigna radiata) especially during seed storage. To provide background information for chemical ecology studies, we examined the externalmorphology of the antennal, maxillary palp and labial palp sensilla of this insect with scanning electron microscopy. The antennae of adult C. chinensis exhibited sexual dimorphism. The female have serrated antenna and the male have pectinate morphology. Eight sensillum types have been observed on the antennae of both sexes: $B\ddot{o}hm$ bristles, sensilla chaetica, sensilla trichodea, sensilla basiconica, sensilla styloconicum, sensilla coeloconica, sensillum campaniformia, sensilla cavity. There are no differences on the morphology of maxillary palp and labial palp between female and male. Four different types of sensilla are present on the labial and maxillary palps of both sexes of C. chinensis: sensilla chaetica, sensilla twig basiconica, sensilla basiconica, sensilla digitiformia.

Psalidoremus is one of the subgenus which consists of five species and eleven subspecies through Taiwan, Japan, Korea and north eastern part of China which present strong endemism to their distribution. While most of advance studies focus on the new species or subspecies from this taxon, this paper suggests paleogeographical assumption and hypothesis of how they diverged from common ancestors. Phylogeographical patterns illustrated by the distribution of five species, which including Prosopocoilus inclinatus, Prosopocoilus hachijoensis, Prosopocoilus dissimilis, Prospocoilus pseudodissimilis, Prosopocoilus motschulskii respectively, has been assessed in this research. Speciation history is suggested by morphological tendencies especially in male mandibles with assumption from geographical patterns of under sea level.

This paper presents the confirmed occurrence of the reed beetle genus Sominella Jacobson, 1908 in North Korea, based on a specimen of S. macrocnemia (Fischer von Waldheim, 1824). Photographs of the habitus, main diagnostic characters, and a distribution map in Korea are provided.

Polyphylla laticollis manchurica Semenov, 1900, is a critically endangered species in the Republic of Korea and is strictly protected as a Class I endangered species. Although this beetle species faces a threat of extinction, its ecological understanding is limited. Previous studies conducted on this species in the Republic of Korea have focused only on its taxonomy and mitochondrial genome sequences. Herein, we report an observation of the mating of adults of P. l. manchurica in June 2021, during an ongoing study on Korean beetles. This incidence was reported around light sources from newly constructed townhouses near Geumgang River. Larval habitats were observed along the river between April 2022 and March 2023. Particularly, two larvae were found inside the plant debris, and three were found under the roots of reeds. This study provides key information on the mating ecology of P. l. manchurica that can assist conservation efforts of this critically endangered species.

Diversity or richness and altitudinal distribution of subtribe Carabinae were investigated on Mt. Togyusan in Korea. Of the collected seven species belonging to 4 genera, Carabus sternbergi was the most abundant and Leptocarabus semiopacus and L. seishinensis were relatively abundant than the other species. Although species diversity and species richness indices were higher at the crown site than those at lower sites, more indivisuals were found at low sites. There were relatively more females.

The family Ciidae, commonly known as minute tree-fungus beetles, encompasses approximately 640 species distributed among 43 genera, classified into two subfamilies(Ciinae and Sphidociinae). In South Korea, total 13 species in five genera are known: Cis boleti(Scopoli), C. hieroglyphicus Reitter, C. jezoensis Nobuchi, C. mikagensis Nobuchi & Wada, C. sasajii Kawanabe, C. seriatopilosus Motschulsky, Ennearthron chujoi Nakane & Nobuchi, E. ishiharai Miyatake, E. robusticorne Kawanabe, Neoennearthron bicarinatum Miyatake, Octotemnus japonicus Miyatake, O. laminifrons (Motschulsky), and Xylographus scheerpeltzi Nobuchi. In this study, two Ciidae species, Cis japonicus Nobuchi, 1955 and Orthocis nigrosplendidus(Nobuchi, 1955), are reported for the first time in the Korean Peninsula. Diagnoses of two species, habitus photographs of adult and male genitalia are provided.

The insect industry in Korea is currently undergoing steady expansion. Among the various insects kept as pets or for educational purposes, four mantis species, including Hierodula patellifera (Audinet-Serville), Tenodera angustipennis Saussure, Tenodera sinensis Saussure, and Statilia maculata (Thunberg), are becoming increasingly popular, leading to higher demand. As we aimed to raise mantises, we collected oothecae, some of which were found to be parasitized by dermestid beetles. These parasitoids have been unequivocally identified as Thaumaglossa rufocapillata Redtenbacher based on morphological characters. A diagnosis, habitus photographs, and illustrations of diagnostic characters are provided to facilitate identification. We also present the complete mitochondrial genome (mitogenome) sequence of T. rufocapillata for providing fundamental data for research aimed at controlling pests in the insect industry.
