The physiography and climate of Inaccessible and Nightingale Islands are briefly discussed. The vegetation and the major plant associations are described. Notes are given on the ecology and distribution of each taxon. Taxa newly recorded for Inaccessible Island include Agrostis goughensis, A.holgateana, A. wacei, Calamagrostis deschampsiiformis, Carex thouarsii var.  recurvata, Conyza albida, Elaphoglossum campylolepium and  Uncinia meridensis. One species, C.  albida, is alien to the Tristan group. Two native ferns Asplenium platybasis var.  subnudum and Blechnum australe were found on Nightingale Island for the first time, and the presence of introduced Malus domestica orchards was recorded. Two unidentified taxa were found that may represent new species:  Elaphoglossum sp. at Inaccessible Island and Apium sp. at both Inaccessible and Nightingale Islands. The total number of vascular plant species recorded at Inaccessible and Nightingale Islands now stands at 98 and 43, respectively, of which 26 (28%) and seven (16%) are introduced species. Only Airiplex plebeja and two species of Cotula occur at Nightingale Island but are absent from Inaccessible Island.

Two new species in the genera Thyone and Havelockia are described and illustrated based upon specimens collected from off the southeastern Brazilian coast. Thyone florianoi sp. nov. is characterized by having two pillared body wall tables with four-holed discs and introvert with multilocular tables. Thyone crassidisca is recorded herein for the first time from the South Atlantic Ocean (Brazil). Havelockia mansoae sp. nov. is distinctive in having two pillared body wall tables with four-holed discs and introvert with plates. This is the first record of the genus Havelockia from Brazilian waters.

Ascension and Saint Helena Islands are isolated volcanic islands in the South Atlantic Ocean. Records of annelids from the family Amphinomidae, commonly known as fireworms, are rare. Fireworm species recorded in both localities includeEurythoe complanataandHermodice carunculata,which are broadly distributed throughout the Atlantic Ocean. Here we present the characterization of both species from a recent expedition to Ascension and Saint Helena. Morphologically, specimens fromH. carunculatacorrespond to the West Atlantic population, whileE. complanataspecimens were clearly identified based on chaetal type. A genetic analysis, including material from Ascension and Saint Helena Islands, will be necessary to elucidate the genetic connectivity across the Atlantic Ocean.

<p>The original material of <em>Isopterygium tristaniense </em>Dixon, an endemic species of the Tristan da Cunha archipelago in the central South Atlantic Ocean, is taxonomically evaluated and some details of its morphology are illustrated. The species is found to be conspecific with the Holarctic <em>Pseudotaxiphyllum elegans </em>(Brid.) Z.Iwats. and it is the third record of the species in the Southern Hemisphere. The global distribution of this species is reviewed and the distribution patterns of the South Atlantic mosses are briefly discussed.</p>

The nasocorine plant bug genus Campylomma Reuter from Japan and neighboring regions is reviewed. Twelve species are currently recognized. Several species, which have pale basic coloration, are rediagnosed, with emphasis on the male and female genitalia as significant taxonomic characters. Two new species, C. fukagawai and C. tanakakiana, are described and figured, and C. marjorae Schuh is reported from Japan for the first time and diagnosed. The females of three taxonomically confused species, C. eurycephala Yasunaga, C. livida Reuter and C. lividicornis Reuter, are documented in detail and figured for the first time. Female specimens of the most frequently encountered congeners, C. lividicornis Reuter and C. livida Reuter, can now be unequivocally identified. Confidently associated final-instar immatures are figured for C. aterrima Yasunaga and C. livida Reuter. Confirmed host plant associations are reported for most treated species. Campylomma chinensis [= chinense] Schuh is proposed as a junior synonym of C. livida Reuter, and C. chichijima Carvalho is regarded as nomen dubium. A checklist and a key to species are provided, which are applicable to the faunas of Japan, and of Korea, NE China the Russian Far East and Taiwan as well.

The family Entomolepididae is represented in the South Atlantic Ocean solely by Spongiopsyllus, a monotypic genus found previously in association with sponges. A recent survey on the Boa Viagem Reefs, located off Salvador, Bahia State, on the northeastern region of Brazil, has revealed a new species of the genus, Spongiopsyllus redactus n. sp., found associated with the endemic scleractinian coral Mussismilia hispida (Verrill). The new species is distinguished from its congener, S. adventicius Johnsson, 2000, by differences in the number of segments of the antennule, the ornamentation of the distal endopodal segment of the antenna, and the setation of the maxilliped and P1. An updated key to the species of Entomolepididae is also provided.

As part of the sampling efforts during the DIVA-II expedition several Tanaidacea of the genus Neotanais were captured in the Guinea and the Cape Basin in the tropical and southern East Atlantic Ocean. Two different species were sampled, Neotanais rotermundiae sp. n. from the Guinea and Neotanais guskei sp. n. from the Cape Basin. The distribution of both species is limited to these basins. A full description for both species is presented. Neotanais guskei sp. n. is the largest Neotanais reported for the South Atlantic Ocean.

The calcareous crusted epiphytic algae are a group of extremely delicate, fragile and poorly studied algae. The subfamily Melobesioideae (Corallinophycidae, Rhodophyta) includes the genus Melobesia, which has no record of molecular analysis.However, thanks to measurement data, it was possible to find enough similarity for taxonomic identification of two species: Melobesia rosanoffii (Foslie) Lemoine, described for the first time in South Atlantic Ocean, and Melobesia membranacea (Esper) Lamouroux, first described in southern Brazil. The group has undergone several changes of classification from animals to plants. Today crusty coralline algae have great importance due to the possibility of easy spore dispersal between oceans.

AbstractSeven species of Erythropini from the northeast Atlantic and one from the northwest Atlantic are dealt with. Four are described as new species, and three are new to science but remain unnamed because of mutilated condition. A known species Katerythrops oceanae, is described for the first time for the male pleopods and a revision of the diagnosis of the genus is presented. Five are pelagic species while three were obtained from the stomach contents of demersal fishes. Huit especes d'Erythropini de l'Atlantique sont traitees, dont sept du nord-est et une du nordouest de cet ocean. Quatre sont decrites comme nouvelles et trois sont nouvelle pour la science, mais non nommees en raison de leur condition mutilee. Les pleopodes males d'un espece connue, Katerythrops oceanae, sont decrits pour la premiere fois et la diagnose du genre est revisee. Cinq especes sont pelagiques et trois proviennent de contenus stomacaux de poissons demersaux.

AbstractThe present study describes a new species, Ligophorus uruguayense, parasitizing the gills of Mugil platanus Günther, 1880 from the coast of Uruguay. It differs from all other species of the genus mainly in the shape of the ventral bar, the thick process at the distal end of the inner root of ventral anchors, the J-shaped penis accessory piece and the vaginal tube showing transverse annulations at its distal end, the host species, and geographical distribution. This is the first description of a species of Ligophorus from a mullet in the South Atlantic Ocean.
