As a result of continuous taxonomic investigations of Korean crabs, Pugettia intermedia Sakai, 1938 is newly reported from Korean waters. Pugettia intermedia had previously been reported in Korean fauna, but the previous reports of P. intermedia were resulted in misidentification of P. quadridens (De Haan, 1839). Pugettia intermedia differs from P. quadridens in having two subequal medial lobes of the first pleopod in male. In P. quadridens, one of the two medial lobes is about half-length of the other. Pugettia intermedia occurs on the southern coast of the Korean peninsula. The descriptions and illustrations of this species are provided herein.

A squillid stomatopod, Oratosquilla fabricii, collected from Jindo Island, is reported for the first time in Korea. The family Squillidae differs from other families by the presence of more than four intermediate denticles of telson. This species is distinguished from O. oratoria, another Oratosquilla species recorded in Korea, by the presence of an armed submedian carinae on the fourth abdominal somite and dark patches on the second abdominal somite. In the present study, detailed descriptions and illustrations of O. fabricii are provided. A key to the species of Korean Oratosquilla species is also presented. With this new record, the number of stomatopod species in the Korean fauna has increased to 16.

Kim (1970) was an early, comprehensive foundation for the taxonomy of Korean spider wasps. All the species therein are reviewed, and an annotated checklist comprising 21 species is presented. Species names are corrected in terms of current taxonomy. Based on the re-examination of voucher specimens, five misidentifications are rectified, of which two species rectified as Priocnemis(Leptopriocnemis) cyphonota and P.(Umbripennis) pseudojaponica are new to Korea. Also, occurrences of two species (Anoplius eous and An. viaticus) in Korea, which was doubted by Lelej et al. (1994), are confirmed. On the other hand, exclusions of two species (Irenangelus perinx and Priocnemis mitakensis) from the Korean fauna are proposed. However, the need for further study on six species (Anoplius reflexus, An. infuscatus, Arachnospila eisukei or Ar. fumipennis eisukei, Auplopus obtusus, Priocnemis irritablis) historically mentioned for the Korean fauna is newly recognized. The current taxonomic status of those species is briefly discussed.

A taxonomic examination of hydroids collected from the subtidal zones of Ulleungdo and Dokdo located in the East Sea of Korea from 2017 to 2023 was conducted. Through this study, Antennella aurantia n. sp., a new species belonging to the family Halopterididae, was newly added to the hydrozoan fauna of Korea. This new species is clearly distinguished from similar species by the different morphology and size of the hydrothecae, lateral nematothecae, and gonothecae. By comparing the 16S rRNA sequence with 7 recorded species within the Antennella, the interspecific genetic distance to the new species was 8.2-28.9%, which is very high compared to the intraspecific variation of 0.0%, showing that it was clearly distinguished from other species. As a result of this study, a total of 4 Antennella species are reported in the hydrozoan fauna of Korea.

To study the faunal compositiion of spiders as natural enemies of the insect pests and their seasonal fluctuation in paddy fields of Taegu, the survey was carried out 12 times between June and September. 1971. 1. The spiders collected in paddy field of Taegu during the survey period were 45 species of 30 genera of 10 families. 2. In percentage composition the spiders of the genus Pirata were most abundant. Among the other genera, the species of the genus Neoscona, Lycosa, and Marpisa were more abundant in the above-written order. 3. Pirata subpiraticus, Neoscona doenitzi, Lycosa sp., Pardosa T-insignita and Marpisa magister were the 5 major species of abundant spiders. 4. Comparing the spider-fauna of the paddy field of Korea with that of Japan, Taiwan and Thailand, 2 species of 2 genera of the family Gnaphosidae were found in Korea only The abundant and common species It·ere deeply different each other. 5. Pirata subpiraticus, Lycosa sp. and Pardosa T-insignita appeared abundantly between June and July while Neoscona doenitzi and Marpisa magister were few in these periods. But no Pirata subpiraticus, Lycosa sp. and Pardosa T-insignita appeared in August while Neoscona doenitzi and Marpisa magister were abundant in this period. Then, in September as between June and July, Pirata subpiraticus, Lycosa sp. and Pardosa Tinsignita were abundant while Neoscona doenitzi and Marpisa magister decreased.

The aim of this study was to compile a species list of endemic water beetles of Mongolia and determine their distribution patterns. A total of 1,179 individuals of endemic water beetles were collected from nine different sub-basins (123 sample points) throughout the country. Currently, 21 endemic and sub-endemic species have been recorded in Mongolia. Eight of these species were strictly endemic. The endemic and sub-endemic species were found only among four families: Dytiscidae (10 out 99 spp.), Gyrinidae (1 out 7 spp.), Helophoridae (5 out 16 spp.), and Hydraenidae (5 out 13 spp.). The rate of endemism was higher in Hydraenidae than other families (38.4%). Endemic beetle fauna was most similar between the Onon and Kherlen River Basins (80%). Helophorus parajacutus Angus, 1970 was common in five sub-basins, but Agabus kaszabi $Gu{\acute{e}}orguiev$, 1972, Gyrinus sugunurensis Nilsson, 2001 and Ochthebius mongolicus Janssens, 1967 were recorded from only one sub-basin. In terms of sub-endemic species, Mongolia was mostly similar to the fauna of Eastern Siberia, Russia (73.7%) than other neighboring regions. Due to Mongolia's vast territory and different natural zones, endemism was exceptionally low (12.4%), but these data provide baseline information of endemic and rare species for their further conservation.

Chemical insecticides released into the environment may have adverse biological effects. Therefore, there is a need for ecofriendly insecticides for mosquito control. Xerophytic plant extracts that may provide more ecofriendly active component were evaluated against Culex pipiens 4th instars. Plant extracts prepared using different solvents with a Soxhlet apparatus and different concentrations were tested against Culex pipiens larvae. The effects were observed at 24 h and 72 h intervals and $LD_{50}$ and $LD_{90}$ values determined. Chloroform ($CHCl_3$) and ethyl acetate (EtOAc) extracts of Althaea ludwigii were the most effective against Cx. pipiens $4^{th}$ instars, but were highly dependent on extract concentrations and exposure time. Results suggest that A. ludwigii extracts contain bioactive compounds, such as phenols and saponins, that may provide effective Cx. pipienslarval control. However, the extract was found to be toxic to zebrafish larvae, and may be toxic to other aquatic fauna. Further studies to determine the active components and toxicity to other fauna are needed.
