  • Fifteen species of poecilostome copepods associated with marine invertebrates, including ten new species, are recorded from intertidal zone in Thailand. New species are Hemicyclops cornutus n. sp. and Hemicyclops parapiculus n. sp. in the family Clausidiidae, Presynaptiphilus trifurcatus n. sp. in the Synaptiphilidae, Anchimolgus kantariensis n. sp. and Anchimolgus palmatus n. sp. in the Anchimolgidae, Kelleria vasfera n. sp. in the Kelleridae, Pseudanthessius stenosus n. sp. and Pseudanthessius phuketensis n. sp. in the Pseudanthessiidae, Doricidola pattayensis n. sp., and Lambanetes mollis n. sp. in the Rhynchomolgidae. Five species are new records of Thailand: Critomolgus gemmatus (Humes, 1964), Doridicola cuspis (Humes, 1964), Doridicola inaequalis (Humes and Ho, 1966), Indomolgus brevisetosus (Humes and Ho, 1966), and Lambanetes stichodactylae Humes, 1982. The female of Lambanetes stichodectylae is described for the first time in the world.

  • Several differences are revealed in the segmentation and setation of the antennule, maxillule, maxilliped and fifth legs between three genera of the family Metridinidae, Metridia, Pleuromamma, and Gaussia. The phylogenetic relationships are cladistically analyzed on the basis of 10 morphological characters. The cladogram shows that Gaussia and Pleuromamma form a sister group, with Metridia which is the first branch to diverge within the family. The presence Of quadritheks on the male antennules of Metridia and Pleuromamma seems to be an important synapomorphy. The loss of quadritheks in Gaussia represents likely evidence of a character reversal into the ancestral condition.

  • Haloptilus caribbeanensis Park, 1970 (Copepoda, Calanoida, Augaptilidae) is redescribed in detail on the basis of an adult female collected from Suruga Bay, Japan. This is the first record of the species from the Indo-Pacific region. Morphology of the Pacific specimen agrees well with that of the Caribbean Sea and Gulf of Mexico specimens, except for the numbers of mandibular teeth. The former has five teeth and the latter six teeth on mandible. The segmentation and segmental aesthetasc numbers of female antennules of H. caribbeanensis are compared with those of five species of Haloptilus (H. angusticeps, H. fons, H. longicomis, H. ornatus and H. spiniceps). These characters show morphological differentiation at the species level. H. caribbeanensis has no aesthetasc on the proximal segments II, IV, and VI of the female antennules.

  • 1994년부터 주로 한국의 조간대 해조류 및 아조하대 바닥 퇴적물을 걸러 채집하여 보관중이던 Thalestridae과의 갈고리노벌레류를 재검토한 결과 Phyllothalestris sarsi Sewell, 1940와 Dactylopusia falcifera Willey, 1935의 2종을 추가로 동정하였다. 이 종들은 태평양에서 처음으로 보고되는 종이다. 2종 모두 원기재가 부족하여 한국산 표본을 재료로 하여 재기재를 하였고, 근연종과의 형질비교 및 변이성 등에 관하여 고찰하였다.

  • Two new species of poecilostomatoid copepods associated with echiurans are described from an intertidal mud flat in the Yellow Sea. A new genus Echiuricopus is created to accommodate two new species, E. aprilis and E. tenuipes. Major differences between the two new species are displayed in body length, length of caudal ramus seta I, length/width ratio of leg 5 exopod, and armature of the first antennular segment. Echiuricopus n. gen. is closely related to the genus Goidelia Embleton, 1901, but is distinguished from the latter chiefly by having seven caudal setae, a claw-like process on the first antennular segment, one claw-like process on the maxillary syncoxa, the absence of an inner coxal seta on legs 1-4, different armatures on legs 1-4, and an elongate leg 5 exopod.

  • All copepodid stages and free-swimming adults of Ergasilus hypomesi Yamaguti collected from plankton samples from a brackish lake in Korea are described. The antennule remains a four-segmented appendage until copepodid V. The antenna of copepodid I carries a vestigial exopod. Sexual dimorphism first appears at copepodid IVwhose males bear primodial maxillipeds. Leg 5 also is sexually dimorphic from copepodid IV onwards, with its free segment bearing three setae in the female and two setae in the male. Morphological features of some appendages appearing during copepodid development are discussed. It is noticed that the early copepodids of the Ergasilidae show the characteristic setation on the biramous legs and proximal segments of the antennule.
