| A new family Cristacoxidae is proposed to accommodate the monotypic genera Cristacoxa gen. nov., Noodtorthopsyllus Lang (ex Canthocamptidae) and Cubanocleta Petkovski (ex Laophontidae). Cristacoxa petkovskii gen. et spec. nov. is described on the basis of a single male collected from coralline sand of Bonaire, West Indies. N. psammophilus Noodt and C. noodti Petkovski are redescribed and refigured on the basis of new material from the Galapagos (Isla Santa Cruz), the West Indian Islands (Curaçao, Klein Curaçao, Bonaire) and the Canary Islands (El Hierro, Tenerife). The new family is characterised by the presence of an outer spinous process on the first antennular segment, the absence of the antennary exopod, the uniramous mandibular palp, the presence of... |

| A new family of harpacticoid copepods, Adenopleurellidae, is proposed to accommodate the genera <i>Adenopleurella</i>, new genus, </i>Sarsocletodes</i> Wilson, <i>Miroslavia</i> Apostolov, and <i>Proceropes</i>, new genus. The genus <i>Sarsocletodes</i> is removed from the Laophontidae T. Scott on the basis of the reduced nature of leg 1 which cannot be attributed to heterochronic (neotenic) events. <i>Sarsocletodes secundus</i> Smirnov is placed in a new genus, <i>Proceropes</i>, on account of the primitive P1 and P5, and is considered the most primitive member of the family. <i>Miroslavia longicaudata</i> is excluded from the Cletodidae T. Scott and is most... |

| Sublittoral meiofauna of 24 stations was monitored over 4 years (1984-1987) in and around a dumping site for TiO<sup>2-</sup> acid waste in the Southern Bight of the North Sea off the Dutch coast. The meiofauna was examined quantitatively and qualitatively with special reference to the nematode and the copepod community structure down to species level and to the trophic structure of the nematodes. Biological, sedimentological, geographical parameters and the concentration of several heavy metals were subject to multivariate statistical analysis and classification techniques to evaluate the impact of the TiO<sup>2-</sup> dumping activities. The meiofauna is dominated by nematodes, copepods, gastrotrichs and turbellarians. There is a... |

| The discovery of a new stage in the life cycle of the Tantulocarida is reported. A sexual female, collected from a deep-sea harpacticoid copepod host, was removed from the trunk sac of the preceding tantulus larva. This female is a free-living and nonfeeding stage which presumably mates with the free-swimming adult male previously described. The female comprises a cephalothorax, probably incorporating 2 limbless thoracic somites, 2 free pedigerous trunk somites, and 3 limbless trunk somites. It also possesses paired antennules, the only well-defined cephalic appendages present at any stage in tantulocaridan life history. There is a median genital aperture, the copulatory pore, located ventrally on the cephalothorax at about the level of the incorporated... |

| A new genus of Tantulocarida, Stygotantulus, is described based on material from an anchialine pool on Lanzarote, Canary Islands. It is the most primitive tantulocarid known and is ectoparasitic on representatives of at least two families of harpacticoid copepods. It is distinguished by the presence of 7 abdominal somites in the tantulus larva. The musculature of the penis on trunk somite 7 of the male suggests that it is derived by modification of the seventh thoracopods. The importance of trunk somite numbers in maxillopodan systematics is reexamined and an attempt is made to apply the concept of homology to the developmental processes determining somite numbers. The classification of the Crustacea, including the Tantulocarida, proposed by Starobogatov... |

| Asterocheres reginae n. sp., of the family Asterocheridae, is described from the spongeAgelas clathrodes (Schmidt) collected at Carrie Bow Cay, Belize. It inhabits the internal canal system of its sponge host. A detailed description of both sexes is presented, and emphasis has been placed on the recognition of homologies between the limb segments and armature elements in accordance with the new evolutionary scheme established by Huys & Boxshall (1991). |

| Amphicrossus altalis, n.sp., belonging to the primitive poecilostomatoid family Erebonasteridae, was found at a depth of 2420 m at the Juan de Fuca Ridge off British Columbia. The male of an Amphicrossus species is described for the first time. The new copepod differs from the two recognized species of Amphicrossus in its body surface being not highly ornamented with spinules, its smooth anterior surface of the labrum, and the dimensions of the fifth leg. New records for Benthoxynus spiculifer Humes, 1984, Aphotopontius forcipatus Humes, 1987, and Stygiopontius quadrispinosus Humes, 1987, are included. The clausidiid genus Tychidion is redescribed and its taxonomic position discussed. |

| Males of the two known species of Mormonilla Giesbrecht are described in detail for the first time. They have reduced or vestigial mouthparts and are probably non-feeding. Males have a single testis and produce a single spermatophore. Male antennules are geniculate. A system of probable segmental homologies for the antennulary segments is proposed and the supporting evidence for this system discussed. Females carrying egg sacs are reported and figured for the first time. Mormonilla is unusual amongst copepods in producing paired egg sacs from a common medial genital aperture. |

| Males of two new species of Cylindropsyllus Brady, 1880 (Cylindropsyllidae) are described. Cylindropsyllus ibericus sp. n. is based on a single specimen from Portugal previously misidentified as C. laevis Brady, 1880; C. govaerei sp. n. is reported from Corsican shell-gravel. The boreomediterranean distribution of C. laevis is confirmed and a key to the species of Cylindropsyllus is presented. Redescriptions are provided for the two species of Cylinula Coull, 1971, the type species C. proxima Coull, 1971 and C. arganoi Cottarelli and Venanzetti, 1989. The relationships of Cylindropsyllus, Cylinula and Evansula Sars, 1909 are briefly discussed. |

| A new genus and species of Cylindropsyllidae (Copepoda, Harpacticoida), collected from shallow subtidal sand in the Southern Bight of the North Sea, is described and illustrated. Willemsia calceola gen. et sp. n. exhibits a unique kind of sexual dimorphism on the male P3 not observed thus far in any other harpacticoid. It is further distinguished from all known Cylindropsyllinae by the absence of an isolated midventral copulatory pore, the fades of the P2-P3 in the female and the peculiar shape and orientation of the fifth pair of legs in both sexes. Based on the sexual dimorphism of the P2 exopod and P3 endopod, it is suggested that W. calceola shares a sistergroup relationship with Stenocaris kerguelenensis Bodiou, 1977 which is transferred to a new... |

| The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3-5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean. |

| Three free-living tantuli of a new genus and species, Tantulacus hoegi, were discovered among the meiofauna from deep carbonate shell-sand on the Faroe Bank. The host-is unknown. Tantulacus is referred to the Deoterthridae on account of its larval characters. It occupies an intermediate positon between Deoterthron - Aphotocentor and the other deoterthrid genera. It can be readily distinguished from other tantulocaridans by -the- pr.esence of a distinct rigid spine on the endopod of the second to fifth thoracopods. Some aspects of the deoterthrid stylet are discussed. T. hoegi is the fourth tantulocaridan described from the temporary meiobenthos. |

| The deep-sea planktonic copepod <i>Paralubbockia longipedia</i> is redescribed from the type specimens, and a new family of Poecilostomatoida is proposed to accommodate it. The Paralubbockiidae fam. nov. is characterized by two unique plesiomorphies, the ventrally located fifth legs and the retention of a separate maxillulary palp, and by the apomorphic states of the endopods of the swimming legs and of the antenna. The sister group of the Paralubbockiidae is identified as the family Oncaeidae. These are the only two poecilostomatoid families that have retained a vestige of the geniculation mechanism in the antennules of the male. The genus Laitmatobius Humes is here regarded as incertae sedis within the lineage comprising the Oncaeidae and the... |

The Neobradyidae are considered remnants of a formerly widespread group and brief reference is made to the phylogenetic relationship of the family. |

| During a synoptic survey carried out in April-May 1986, 171 localities were sampled in the North Sea as delimited by the Straits of Dover in the south and approximately by the 100m isobath in the north. Meiobenthos included Nematoda, Copepoda, Turbellaria, Gastrotricha, Polychaeta, Oligochaeta, Priapulida, Kinorhyncha, Ostracoda, Halacarida, Isopoda, Tanaidacea, Bryozoa, Cnidaria, Sipunculida, Echiurida, Nemertini and Tardigrada. Nematodes were the dominant group in virtually all stations, their densities ranging from 61 to 4167 individuals. 10cm<sup>-2</sup>. Only in the Southern Bight, where nematode numbers were low, did harpacticoids sometimes represent the dominant meiobenthic taxon. There was a tendency for nematode (and total... |

| A new family Rotundiclipeidae is proposed for an anchihaline cave-dwelling harpacticoid Rotundiclipeus canaricnsis gen. nov:, sp. nov. from Tenerife, Canary Islands. It is suggested that the family should be placed in the Cervinioidea grouping also the chiefly deep-sea Cerviniidae and the mesopelagic Aegisthidae. Because of numerous unique and unusual derived traits, the smallsized Rotundiclipeidae are regarded as the advanced sistergroup of the Cerviniidae-Aegisthidae complex whilst the Cerviniidae are standing closest to the cervinioid ancestor. In the context of Stock's (1986) conclusion it is postulated that both the cave-dwelling Rotundiclipeidae and the deep-sea Cerviniidae are originated from a common shallow water ancestor. |

| A new genus, <i>Centobnaster</i>, is proposed to accommodate a single female collected from deep water northeast of New Caledonia. <i>Centobnaster humesi</i>, new species, is placed in the family Erebonasteridae (Poecilostomatoida) on account of the distinct palp on the mandible and the external structure of the female genital system, comprising ventral paired copulatory pores and dorsolateral gonopores. <i>Centobnaste</i>r is considered the most primitive poecilostomatoid copepod known today because of the combined presence of 7-segmented antennules, a separate palp and unmodified gnathobase on the mandible, ventrally located paired copulatory pores, and midventral fifth legs jointed by an intercoxal sclerite.
