Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

Abstract Here, the symbiotic palaemonid shrimp Hamodactylus boschmai is recorded from Korean waters for the first time, based on specimens collected from different invertebrate hosts by trimix diving at depths of between 45 and 60 m in Jejudo Island. This species can readily be distinguished from its congeners by the presence of a distinct supraorbital tooth, the proximal segment of the antennular peduncle having a single tooth on the distolateral margin, the presence of a denticulate lamina along the entire cutting edge of the fingers of the first pereiopod chela, and the chela of the second pereiopods having a strongly hooked tip on the movable finger. An illustrated description, colour photographs, and a comparison of partial mitochondrial cytochrome c oxidase subunit I gene sequences are provided.

A New Species

Abstract Two species of cyclopoid copepods are recorded in this study. (1) A new species of bomolochid, Orbitacolax brevispinus n. sp. (Crustacea) is described based on adult females collected from the gill filaments and inner surface of the opercula of red barracuda, Sphyraena pinguis Günther (Perciformes: Sphyraenidae), captured in Korean waters. The new species differs from its congeners by the possession of two pairs of spines on the dorsal surface of the cephalothorax located just posterior to the rostrum and a different setal formula on the distal exopodal segments of legs 2–4. (2) A taeniacanthid Cirracanthus inimici (Yamaguti et Yamasu, 1959) (Crustacea) is redescribed based on the specimens collected from the gill filaments and inner surface of the opercula of devil stinger, Inimicus japonicus (Cuvier) (Scorpaeniformes: Synancellidae). This finding is the first record in Korean waters and the first description of male. A checklist of parasitic copepods of the families Bomolochidae Sumpf, 1871 and Taeniacanthidae Wilson, 1911of Korea is also provided.

Spatio Temporal

Species of the genus Acartia Dana, 1846 (Copepoda, Calanoida, Acartiidae) are predominant and widespread in estuarine and coastal waters worldwide, but the spatio-temporal distribution of each species is very restricted (Bradford 1976). Acartia pacifica Steuer, 1915 has been recognized as a common species in euryhaline waters on the Korean coasts from summer to fall (Suh et al. 1991; Soh & Suh 1993; Park 2005). Recently, Ueda and Bucklin (2006) described A. ohtsukai from low saline waters in the Ariake Sea, Western Japan, which has been confused with A. pacifica s. s. on the basis of their morphological and genetic differences (0-3% in mtCOI sequences). According to Ueda and Bucklin (2006), A. ohtsukai has a restricted distribution in continental brackish waters of East Asia with a relict population in the Ariake Sea, while A. pacifica is broadly distributed in coastal waters in the tropical/subtropical Indo-West Pacific regions. During our investigation of planktonic copepods A. ohtsukai was recorded in Korean waters for the first time. This species may have been confused in the past with its sibling species A. pacifica by Korean researchers. Therefore, we compare the spatio-temporal distributions of A. pacifica and A. ohtsukai in Gwangyang Bay, southern Korea.
