  • Two diogenid hermit crab species, Dardanus lagopodes and Diogenes deflectomanus, are newly reported from Korea. Dardanus lagopodes is distinguished from the other species of genus Dardanus in Korea by having setae with cream-colored tips on the cephalothorax and the following characteristics: ocular peduncles somewhat longer than antennular peduncles, and the pereopod without a longitudinal sulcus and scute-like projections. Diogenes deflectomanus is similar to D. nitidimanus but can be distinguished by having the fixed finger of the left cheliped bent slightly downwardly and the following characteristics: slightly shorter ocular peduncle, elongated left cheliped with small granules on the surface, right cheliped without calcareous teeth on the cutting edge of the dactylus, and the minute spine of post-median margin of the telson is not well developed. The geographical distributions of these two species are extended by the present study. In particular, D. deflectomanus in the current study is the first report outside Chinese waters. Now, 20 species of the family Diogenidae are known in Korean waters.

  • The leucosiid crabs are common species on soft sediment from the intertidal flat to shelf and slope depths. The genus Nursia Leach, 1817 is characterized by the pentagonal shape of the carapace and the presence of the buccal cavern on the pterygostomian region. As a result of the systematic study on the Korean brachyuran species, Nursia rhomboidalis (Miers, 1879) is newly recorded in Korean fauna. Korean Leucosiidae is now composed of 14 species belonging to eight genera. The description and illustrations of this species are provided.

  • As a result of continuous taxonomic studies on the Korean crabs, Carcinus aestuarii Nardo, 1847 belonging to the superfamily Portunoidea is newly reported from Korean waters. Carcinus aestuarii has characteristics as followings: cardiac, hepartic and brachial regions are divided by deep furrow; shape of three lobes in frontal area is flatter with hairy; inside of carpus is with one sharp tooth; the posterior-lateral margin of the carapace is concave, and so on. The examined specimen doesn't have hairy and bump on outer margin of the chelipeds which differed from the previous description of the specimens collected from Tokyo Bay, Japan. Here, the diagnosis and the picture of Korean specimen is provided. Korean portunoids currently consist of 20 species belonging to 10 genera.

  • Alpheid shrimp are found worldwide in temperate and tropical waters. They live in burrows in sandy and muddy bottoms and also in crevices of rocks and coral reefs. The genus Alpheus is the most diverse group of alpheid shrimp. Continuous taxonomic study on shrimps collected from Korean waters revealed that an alpheid shrimp collected from Daesambudo Island was identified as Alpheus compressus. This species belongs to the brevirostris group of the genus Alpheus and is distinguished from other known species of the genus Alpheus in Korea by the laterally compressed body. Korean Alpheus fauna now consists of 15 species of five species groups.

  • Two caridean shrimps, Eualus biunguis (Rathbun, 1902) and Argis toyamaensis (Yokoya, 1933), collected from the Korean continental slope of the East Sea at depths of 850-870 m are reported as new to the Korean caridean fauna with brief descriptions and illustrations. A hippolytid shrimp, E. biunguis, is distinguished from the congeners by the minute che1alike appearance of dactyli of the last three pereopods and the large pyriform eye. A crangonid shrimp, A. toyamaensis, differs from the Korean species of the genus in having the posterior acute spines of submedian carinae on the sixth abdominal somite.

  • The genus Athanas is a member of alpheid shrimps living in temperate and tropical waters worldwide. Species of the genus Athanas are small and inhabit coral reefs, rock or muddy bottoms. As a result of continuous taxonomic research on shrimps collected from Korean waters, Athanas parvus is newly added to Korean fauna through the description of adult form. Athanas parvus is distinguished from A. japonicus by the biunguiculated dactyli of third, fourth and fifth pereopods and spines on ischium of first pereopod. The Korean Alpheidae fauna now consists of nine genera and 27 species including two species of the genus Athanas.
