A hyalid amphipod, Protohyale pumila (Hiwatari and Kajihara, 1981), collected from Jeju Island is reported for the first time in the Korean fauna. The species is characterized by the presence of a short apical spine on the palp article 4 of maxilliped, a distinctly large and blunt cusp on the propodus of male gnathopod 1, and a distal truncate process on the palm of male gnathopod 2. Herein, the present species is described and illustrated. Korean hyalid amphipods now are composed of four species belonging to three genera. Voucher specimens were deposited in the Marine Arthropod Depository Bank of Korea, Seoul National University.

A newly recorded hyalid species, Protohyale (Boreohyale) triangulata (Hiwatari, 2003), of Korean waters is reported with a description and illustrations. In this paper, the validity of its generic and subgeneric categories is considered. Protohyale triangulata has a specific shape of the propodus of gnathopod 1 in the matured male, forming a triangle with a subquadrate posteroproximal corner, and the palm and the posterior margin are not clear. This major characteristic feature serves to distinguish it from other Korean hyalid species. We also reexamined some previous reports of Korean hyalid species. It seems that this species had been confused with Hyale rubra in Korea.

This study on the five families (Anamixidae, Colomastigidae, Eophliantidae, Eusiridae, and Hyalidae) of fammaridean amphipods of Ulreung Island was based on the materials collected at eight localities in Ulreung Island. Nine speices of seven genera were identified. Of these, three (Paranamixis denticulus, Colomastix prionotos, and Hyale bisaeta) were new to science. Three species (Ceinina japonica, Eusiroides monoculoides japonicus, and Allorchestes angusta) were new recordsfor Korean waters. These six species were descirbed with illustrations.
