Abstract

In our ongoing efforts to explore the species diversity of the harpacticoid fauna in Korea, we present findings on four newly identified species from family Tegastidae Sars, 1904. Although this family is frequently encountered in phytal communities, the diversity of tegastid copepod species within Korean waters largely remains to be elucidated. Drawing from our collections of tegastid harpacticoids from Chuja-do and Geomun-do Islands, we provide morphological descriptions for Tegastes lobus sp. nov., T. tresetosus sp. nov., T. pilosus sp. nov., and Syngastes acutus sp. nov., and propose their taxonomic relationships in relation to other species within the genus. Finally, we update the list of tegastid harpacticoids found in Korea and provide a key for identifying the six confirmed species from this region.

The research on three Tegastes species was partially supported by the management of Marine Fishery Bio-resources Center (2023) funded by the National Marine Biodiversity Institute of Korea (MABIK) and the research program of the Korea Institute of Ocean Science & Technology (Contract No. PEA0116) to J. Lee. Discovery of Syngastes acutus sp. nov. was also financed by a research program(HNIBR 202101101) of the Honam National Institute of Biological Resources (HNIBR) to J.G. Kim.
