The red algal family Solieriaceae is represented by the three genera Solieria, Meristotheca and Eucheuma at Lord Howe Island (31�33'S.,159�05'E.). Each genus is represented by two species, one of which is widespread geographically and the other newly described. The new species (Solieria anastomosa, Eucheuma deformans, Meristotheca procumbens) are characterized vegetatively and reproductively, as are the three previously described species [Solieria robusta (Greville) Kylin, Eucheuma serra (J. Agardh) J. Agardh, Meristotheca papulosa (Montagne) J. Agardh]. Mychodea halymenioides Zanardini, which is based on a Lord Howe specimen, is placed in synonymy with Meristotheca papulosa. Partly as a result of the Lord Howe study, the Solieriaceae is recircumscribed using a suite of characters that is taxonomically more useful than that currently delimiting the family.

Two new species of South African Syllidae of the genusSyllisLamarck, 1818 are described.Syllis unzimasp. nov. is characterized by having unidentate compound chaetae with long spines on margin, a characteristic colour pattern and its reproduction by vivipary. Vivipary is not common among the polychaetes, but most representatives occur in the family Syllidae Grube, 1850 (in five otherSyllisspecies, two species ofDentatisyllisPerkins, 1981 and two species ofParexogoneMesnil & Caullery, 1818).Syllis unzimasp. nov. differs from the other viviparous species in having large broods (>44 juveniles) which develop synchronously. Development of the juveniles is similar to that of free-spawningSyllisspecies, but the appearance of the first pair of eyespots and the differentiation of the pharynx and proventricle occur later inS. unzima.Syllis amicarmillarissp. nov., is characterized by having an elongated body with relatively short, fusiform dorsal cirri and the presence of one or two pseudosimple chaeta on midbody parapodia by loss of blade and enlargement of shaft.Syllis unzimasp. nov. was found in high densities on culturedHolothuria scabraJaeger, 1833 with single specimens found on a culturedCrassostrea gigasThunberg, 1793 and on coralline algae, respectively, whileS. amicarmillariswas found mainly in sediment outside an abalone farm and less frequently on culturedHaliotis midaeLinnaeus, 1758. We discuss the possible benefits of the association withH. scabratoS. unzimasp. nov.

Prochelator tupuhi sp. nov. is the first record of the genus Prochelator Hessler, 1970 from Southern Hemisphere waters, and the first record of the family Desmosomatidae from New Zealand. The new species can be distinguished from all other species of the genus by the following characters: body elongate, without spine-like ventral elongations on pereonites 1–4, pereonite 1 as high as pereonite 5, mesial lobe of the maxilla much shorter than in the other species of the genus, reaching only half the length of the lateral lobe, carpus of pereopod 1 distinctly produced at the base of the claw, propodus broadest at the articulation to the carpus, tapering distally.

The Family Entomolepididae is composed by 7 genera and 15 species. During a survey on the known species and the search for new species, a new Spongiopsyllus is described associated with sponge Aplysina insularis. The new species has antennule 14-segmented, four setae on both lobes of maxillule, some unique features on the leg setation and the armature of the maxilliped. These characteristics make the new species different from all other congeners in Spongiopsyllus. The diagnosis of Entomopsyllus was also revised once it does not consider the differences to Spongiopsyllus which was created posteriorly to its erection. An analysis of Entomopsyllus stocki also indicated that leg 5 somite and the genital somite are fused, instead of separated as originally stated, the structure is also redescribed. Finally, Parmulodes verrucosus is studied and an up-to-date description is provided, correcting some inconsistencies in the armature formula of the antennule and the leg setation, and providing re-analysis of the other appendages.

A new species of the genus Pseudechiniscus, Pseudechiniscus papillosus sp. nov., is described and figured in this paper. This new species differs from the other species of the genus Pseudechiniscus by plate sculpture that consists of many papillae-like projections. Four new records of Echiniscus species and one new record of a Pseudechiniscus species are also reported in this article: Echiniscus cheonyoungi Moon & Kim, E. melanophthalmus Bartoš, E. nepalensis Dastych, E. trisetosus Cuénot and Pseudechiniscus asper Abe Utsugi & Takeda.

Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains – tepuis. Recently various international speleological expeditions to Churí-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churí-tepui and Auyán-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle larger than the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpi with a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.

Three new species of copepod crustaceans are described from material collected from anchialine and brackish habitats inand around the village of Walengkabola on the coast of Muna Island, to the southeast of Sulawesi. A new species of cy-clopoid, Paracyclopina sacklerae n. sp., was described from material collected from the tidal inflow entering into the bot-tom of sinkholes a few metres inland from the shoreline. Detailed comparisons are made with Paracyclopina orientalis(Lindberg, 1941), n. comb., a closely related congener here transferred from its original genus Cyclopetta Sars, 1913. Theassignment of Paracyclopina Smirnov, 1935 to the family Cyclopettidae is followed here despite uncertainty over the va-lidity of some of the families created by the break up of the former Cyclopinidae. Two new species of Boholina Fosshagen& Iliffe, 1989 are described, based on material from the same sinkholes and from caves located up to 700m inland fromthe coast and exhibiting further reduced salinity down to 1.8 ppt. One species, B. parapurgata n. sp., is very closely relatedto B. purgata Fosshagen & Iliffe, 1989 from Bohol island in the Philippines, the other B. munaensis n. sp., is very closelyrelated to B. crassicephala Fosshagen & Iliffe, 1989 also from Bohol island, but a number of fine scale differences in the leg 5 of both sexes are recognised in each case. Keys to valid species of both genera are provided.

Four new species of Actaecia Dana are described from Australia; three of these (A. bipleura, A. cyphotelson and A. nasuta) are from beaches in south-eastem Australia and one (A. forrnida) is from the mid-eastern coast of Queensland. Specimens from Tasmania identified previously as Actaecia pallida Nicholls & Barnes belong to A. bipleura. The same probably applies to others from New South Wales and Lord Howe Island. The distributions of the six Australian species are noted. A review of the monogeneric family Actaeciidae includes a new diagnosis of Actaecia and a key to species. The distributions of the two New Zealand species are listed.

Four new species of Cumacea are described from deep-sea samples collected around Salomon Islands during the French campaign SALOMON I. Bathylamprops pagesi sp. nov. and Bathylamprops caperatus sp. nov. belonging to the family Lampropidae differ from the all currently known species by the oblique lateral carina running from anterolateral angle backwards. The nannastacid Campylaspis alisae sp. nov. can be identified by the shape of the carapace carinae, especially in dorsal view. The diastylid Oxyurostylis? salomonensis sp. nov. due to the lost of the telson tip, is difficult to assign either to the genus Diastylis Say, 1818 or to the genus Oxyurostylis Calman, 1912. At the moment, it is included provisionally to the genus Oxyurostylis and it differs from the other species in the genus by its flattened eyelobe and the higher number of setae on telson.

Neoceratitis is revised to include six species. N. albiseta, from Madagascar, is described as new. Trirhithrum lycii var. min-imum Bezzi, 1924 is a junior synonym of Ceratitis lycii Coquillett, 1901, new synonym. All known and suspected hostassociations are within the family Solanaceae, with one species (N. cyanescens) infesting tomatoes and several species ofSolanum, whereas the other species with known hosts are associated with Lycium spp. Neoceratitis is probably similar toTrirhithrum Bezzi and particularly to the little known Paratrirhithrum Shiraki. Redescriptions (description in the case of the new species) and illustrations are provided for all the species, and a key to all the species is also provided.

A new candonid genus,Schornikovdonagen. nov., with its type speciesSchornikovdona bellensissp. nov., is described from rheocrene springs of Bell County, Texas. It is designated to the tribe Candonini due to the smooth carapace surface, normal pore openings with sensory seta, the presence of a 5-segmented first antenna, two long sexual bristles on the second antenna in males, the narrowly fused terminal segment of the Md palp, a long penultimate segment of the Mxl palp, two long and one short setae on the terminal segment of T3, the absence of an “e” seta on T3, the presence of a posterior seta on the uropod, the presence of 5 + 2 rows of spines on Zenker’s organ, and other characteristics found in the tribe. The main diagnostic characteristics separating the new genus from the other genera in the tribe are the shape of the carapace, the reduced numbers of segments in the first antenna, reduction or absence of exopodial setae in the second antenna, asymmetrical clasping organs, the uropod with one rod-shaped claw, the different shape of the hemipenis, and differences in parts of the chaetotaxy. Based on these differences, we proposeSchornikovdonagen. nov. as a new genus, with the new speciesS. bellensissp. nov., in the subfamily Candoninae in the family Candonidae.
