Pitfall traps that use ethylene glycol as a preservative solution are commonly used in arthropod research. However, a recent surge in cases involving damage to these traps by roe deer or wild boars owing to the sweet taste of ethylene glycol has prompted the addition of quinone sulfate, a substance with a pungent taste, to deter such wildlife interference. This study aimed to assess the effects of quinone sulfate on arthropods collected from pitfall traps containing ethylene glycol. We strategically positioned 50 traps using ethylene glycol alone and 50 traps containing a small amount of quinone sulfate mixed with ethylene glycol in a grid pattern for systematic sampling at the Gwangneung Forest long-term ecological research (LTER) site. Traps were collected 10 days later. The results revealed a notable effect on ants when quinone sulfate was introduced. Specifically, it decreased the number of ants. In a species-specific analysis of ants, only Nylanderia flavipes showed a significant decline in response to quinone sulfate, whereas other ant species remained unaffected. Additionally, among the arthropod samples obtained in this survey, we identified species or morpho-species of spiders, beetles, and ants and assessed species diversity. Consequently, the utilization of quinone sulfate should be undertaken judiciously, taking into account the specific species composition and environmental characteristics of the monitoring site. Our study also highlighted the significant response of various arthropod groups to variations in leaf litter depth, underscoring the crucial role of the leaf litter layer in providing sustenance and shelter for ground-foraging arthropods. Furthermore, we have compiled comprehensive species lists of both spiders and ants in Gwangneung forest by amalgamating data from this investigation with findings from previous studies.

Two new species of Tanaidacea are described from the eastern coast of Korea; Apseudomorpha n. sp., and Leptochelia n. sp., belonging to the family Metapseudidae and Leptocheliidae, respectively. Apseudomorpha n. sp., is characterized by pleonites 2 and 5 and pleotelson have a large lateral seta; pleopods are biramous, in five pairs, each bearing a two-segmented exopod and a single- segmented endopod; the maxillular palp is two-segmented, with five setae on its distal segment. Leptochelia n. sp., differs from the basis of maxilliped has 4 setae; the uropod exopod is 0.5 to 0.6 times as long as proximal endopod segment and endopod 3 segment is the longest.
