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 taxonomic study on Hoplophrys oatesii Henderson, 1893 was conducted with materials collected from Jejudo Island of Korea by SCUBA diving. H. oatesii is redescribed with some remarks on variations of dactylus and the number of segments of abdomen. The Korean Pisid fauna now consists of seven species of five genera.

The larvae of Oregonia gracilis are described, illustrated and compared with those of other known species of the Oregoniidae. The first zoea of O. gracilis of the present study is somewhat different from that of Hart (1960) especially in having a basis and an endopod of the first maxilliped with 2, 2, 3, 3 and 3, 2, 1, 2, 5 setations, respectively and an endopod of the second maxilliped with 1, 1, 5 setation. It is found the Oregoniidae must be a homogeneous group based on the zoeal morphology. A provisional key for the identification of the known zoeae of the Oregoniidae from the northern Pacific is provided.

The introduced spider crab Pyromaia tuberculata was collected from Korea in 2005 and it was ovigerous. After hatching, larvae were reared in the laboratory at $20^{\circ}C$. The larval stage of the species consists of two zoeal and one megalopal stages. The larvae of the Korean species differ somewhat from those from New Zealand described by Webber and Wear (1981; N Z J Mar Freshwat Res. 15:331-383) and from Brazil described by Fransozo and Negreiros-Fransozo (1997; Crustaceana. 70:304-323.) in the setal presence of the antennule, the maxillule, the maxilla and the maxillipeds, and the abdomen. It is found that Fransozo and Negreiros-Fransozo have overlooked some setae on the basis of the zoeal maxillipeds and that re-examination of their larvae is needed. Also, it is found that the Inachoididae is heterogeneous based on the zoeal morphology because two distinct groups exist in the family.
