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.

The tribe Rhyparini is one of the well-known termitophilous tribes in Aphodiinae. The genus Rhyparus has the largest number of species in the tribe Rhyparini, and only one species, Rhyparus azumai Nakane, 1956 was recorded in Korea. In this study, we report Rhyparus helophoroides Fairmaire, 1893 from Korea for the first time. Diagnosis, photographs of diagnostic characters, key to the Korean Rhyparus, and brief ecological information of the species are provided.

An archostematan beetles, Tenomerga mucida (Chevrolat, 1829), belong to the family Cupedidae is reported in Korea for the first time. We provide the diagnostic information based on morphology with microscophic images of the species compared with Tenomerga anguliscutis.

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.

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.

Three species of seed beetles, Acanthoscelides pallidipennis (Motschulsky, 1874), Bruchidius terrenus (Sharp, 1886), and Kytorhinus senilis Solsky, 1869, from South Korea are reported for the first time. These three species can be morphologically distinguished from other Korean bruchid species by the distinctive color pattern of the elytra, presence of subapical spines on hind femur, and exposed last three tergites of abdomen, respectively. In this study, partial sequences of mitochondrial cytochrome c oxidase subunit I from Korean specimens of these species were generated. In addition, host plants, distribution maps, and photographs of the dorsal habitus and live specimens of each species are also included.

Two species, Lyctoxylon dentatum (Pascoe, 1866) and Melalgus batillus (Lesne, 1902), belong to the family Bostrichidae are reported in Korea for the first time. We provide the brief diagnosis and information on the species and their photographic images.

Rhyssemus Mulsant, 1842, represents one of the largest genera in the tribe Psammodiini, comprising approximately 170 species to date. This group is nearly cosmopolitan, excluding the Neotropical region, with 59 species recorded in the Palearctic region. On the Korean Peninsula, only one species, Rhyssemus koreanus Stebnicka, 1980 was recorded from North Korea. In this study, the genus Rhyssemus is recorded for the first time with a newly recorded species Rhyssemus inscitus (Walker, 1858) from South Korea. Adult specimens were collected from the costal sand dunes in Taean-gun and Jeju island. We herein provide a diagnosis, illustrations of morphological characters, and habitat information. Partial mitochondrial COI sequences of the species are also provided for DNA barcoding.
