  • A new genus Goodingius is proposed to incorporate Hemicyclops adhaerens(Williams), H. arenicolae Gooding, H. elongatus Wilson and H. subadhaerens Gooding, all of which bear the six-segmented female urosome, three mandibular elements (or three elements plus one rudimentary setule), five setae on the first antennular segment, and no inner coxal seta of leg 4. The genus Giardella Canu, a sister taxon of Goodingius, is redefined as possessing eight elements on the third exopodal segment of leg 3, only a single inner seta on the second endopodal segment of leg 4, four spines on the third endopodal segment of leg 4. To the genus Giardella, Hemicyclops caissarum Kihara and Rocha and H. carinifer Humes are assigned, in addition to Giardella ricoensis n. sp., Giardella callianassae Canu, and G. thompsoni A. Scott. Keys to the species of both genera are provided.

  • Two new species of poecilostomatoid copepods, each belonging to the genera Myicola (Myicolidae) and Conchyliurus (Clausidiidae), are described, based on specimens taken from the mantle cavity of the bivalve Dosinella penicillata (Reeve). The host bivalve was collected from the intertidal mud flat near Inchon in the Yellow Sea.

  • Two new species of Clausidiidae, each belonging to the genera Clausidium Kossmann, 1875 and Hippomolgus G. O. Sars, 1917, are described from Korea. Clausidium maximus n. sp. is an associate of a burrowing decapod of the genus Callianassa living on the Korean coast of the Yellow Sea and has, as diagnostic characters, two inner setae on the second endopodal segment of legs 2-4, nine elements on the third exopodal segment of leg 4, an inner seta on the second exopodal segment of male leg 1, and a relatively large body size, exceeding 2.0 mm in the female. Hippomolgus limiticus n. sp. was found in the bottom sediments in the East China Sea. It is similar to H. furcifer G. O. Sars, but distinghuishable from the latter species by having shorter caudal rami, 4-segmented female maxilliped, and inner coxal spine (instead of seta) on legs 2 and 3. This is the first record on the genera Clausidium and Hippomolgus in the West Pacific.

  • Hamaticyclops ahni is described as a new genus and species from the Californian shore of the United States. It was discovered as a victim of the sea anemone Anthopleura elegantissima (Brandt). The new genus is closely related to the genus Hemicyclops but possesses, as significant autapomorphies, three strong claws on the second endopodal segment of antenna and a markedly elongate exopod of leg 5 with its protopod fused to somite.

  • 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.

  • Three new species of Hemicyclops, H. parilis, H. nasutus and H. membranatus are described from Korean coasts. Hemicyclops parilis n. sp. is closely similar to H. gomsoensis Ho and Kim, but distinguishable from the latter species by having the different shape of genital double somite and spermatophore. Hemicyclops nasutus n. sp. is distinguishable from congeners by having five setae on the first segment of antennule and the ratio 4.26 : 1 of the length to width of caudal ramus. Hemicyclops membranatus n. sp. is characterized by the possession of the membranous fringe along margins of cephalothorax and a claw on the third antennal segment.

  • Twenty-two new species of poecilostome copepods associated with marine invertebrates are described from the West Indies, Madagascar, and Pacific coast of Panama. They are Anthessius nosybensis n. sp. and Discanthessius solitarius n. gen. n. sp. in the Anthessiidae; Cemihyclops tenuis n. sp., Hemicyclops tripartitus n. sp., H. humesi n. sp., H. magnus n. sp., and Leptinogaster minuta n. sp. in the Clausidiidae; Schedomolgus crenulatus n. sp. and S. parvipediger n. sp. in the Anchimolgidae; Kelleria multiovigera n. sp. in the Kelleridae; Lichomolgus angustus n. sp. and L. fusiformis n. sp. in the Lichomolgidae; Pseudanthessius acutus n. sp., P. asper n. sp., and Tubiporicola pediger n. gen. n. sp. in the Pseudanthessiidae; Acanthomolgus tenuispinatus n. sp. and Notoxynus lokobensis n. sp. in the Rhynchomolgidae; Eupolymniphilus occidentalis n. sp. and E. brevicaudatus n. sp. in the Sabellephilidae; Enalcyonium robustum n. sp. and E. grandisetigerum n. sp. in the Lamippidae; and O. binoviger n. sp. in the Myicolidae. Hemicyclops geminus Stock is synonymized with H. columnaris Humes which is now known as a species of amphi-American distribution. Hemicyclops columnaris Humes, Modiolicola trabalis Humes, and Ostrincola breviseti Ho and Kim are redescribed.

  • To elucidate phylogenetic relationships among poecilostome families 18S rDNA sequence data were generated for seven poecilostome and one cyclopoid copopods by PCR cloning and sequencing techmiques. Phylogenetic trees were constructed by maximum parsimony, neighbor joining, and maximum likelihood methods using cyclopoid sequence as an outgroup. The results from three different analyses showed that the seven poecilostome families were eiridel into two groups: Clausidiidae-Myicolidae-Synaptiphillidae-bomolochidae and Lichomologidae-Chondracanthidae-Ergasilidae. The molecular phylogenies were consistent with those from the morphological characters. Therefore, these analyses porvide further evidence for the utility of 18S rDNA sequences in addressing phylogenetic relationships among poecilostome families.
