Abstract
Two marine harpacticoid copepods, Psammis longisetosa Sars, 1910 and Pseudomesochra tatianae Drzycimski, 1968, belonging to the family Pseudotachidiidae Lang, 1936 are newly reported from Korea. They were occurred from the subtidal sediments of the southern sea, Korea. Psammis
longisetosa can be discriminated from the congener, P. longipes Becker, 1974, by the setation of mandibular basis and female fifth leg. Korean specimens of P. longisetosa show minute differences with the original description from Norway in the relative length ratio between setae on the fifth and sixth legs in the male. Pseudomesochra tatianae resembles P. similis Lang, 1936, P. gemina Coull, 1973 and P. laptevensis Willen, 1996 in the characteristic features of antennule, antennary exopod, and thoracic legs, but is distinctively characterized by a very reduced maxilliped. The present paper is the first records of genera Psammis Sars, 1910 and Pseudomesochra Scott T., 1902from Korean waters.s of the southern sea, Korea. Psammis
