This paper describes four new species of the bryozoan genus Beania from the Brazilian coast. Two of them have been previously recorded in the western Atlantic as Beania hirtissima (Heller, 1867) and Beania mirabilis Johnston, 1840, respectively; they are redescribed here as Beania americana n. sp. and Beania mirabilissima n. sp. Two reticulate species, Beania correiae n. sp. and Beania metrii n. sp., are newly described. Descriptions of four other species of Beania from the region are also included: Beania australis Busk, 1852, Beania cupulariensis Osburn, 1914, Beania klugei Cook, 1968 and Beania maxilladentata Ramalho, Muricy & Taylor, 2010.

AbstractThyone and Havelockia are worldwide-distributed genera represented in the Western Atlantic by eight and three species, respectively. In this paper, we describe two new shallow-water species from the Brazilian coast: Thyone waltinhoi sp. nov. and Havelockia oraneae sp. nov. These genera are very similar morphologically but the presence of subdivisions in their calcareous rings separates them into different families, Thyone in Phyllophoridae and Havelockia in Sclerodactylidae. To observe the presence of subdivisions, we submerged the calcareous rings in an iodine solution prior to morphological analyses. Thyone waltinhoi sp. nov. differs from its Western Atlantic congeners in its dermal ossicles and Havelockia oraneae sp. nov. differs from its South-western Atlantic congeners in the composition of its introvert ossicles. In addition to species descriptions, illustrations and morphological diagnoses of both genera are provided, along with a synoptic table of their Western Atlantic species, and a discussion of the taxonomic significance of the dermal ossicles and the calcareous ring.

A review of the shallow-water species of the genus Tryphosella from the British Isles is presented and a new species, Tryphosella lowryi, is described. In addition, Tryphosella minima is recorded from this region for the first time. This brings to five the total number of species of this genus now known from the British Isles. All taxa are fully described and illustrated, and a key to the species is provided.

Colonial Ascidians

Four shallow-water species of colonial ascidians of the genus Aplidium are identified in the collections made by divers off the coast of Georgia, U.S.A. One of the specimens, Aplidium ruzickai n. sp., is characterized by a combination of high numbers of rows of stigmata and stomach folds and is described as a new species.

Comoros Island

Shallow water species of galatheid crustaceans collected in Mayotte (Comoros Island), La Réunion and Madagascar have been studied. The collection contains one species of Sadayoshia and seven species of the genus Galathea, including a new species (G. denticulata) closely related to G. amamiensis known from the Indian Ocean and western Pacific waters, a new genus (Macrothea) and species (M. bouchardi). The new genus is closely related to the genus Fennerogalathea and it is easily distinguished by the following combination of characters: (1) rostrum with 4 strong lateral teeth on each side, (2) spines present on epigastric and hepatic regions only, (3) telson completely subdivided, (4) pereiopods 2–4 dactyli sharply biunguiculate. The new genus is also close to Lauriea Baba, 1971, from which it can be differentiated, among other characters, by the shape of the endopod of uropods and the number of male gonopods.

Fifteen species of Calliostomatidae are known to occur in the Californian marine province. Biological observations in situ on shallow water species indicates they are primarily carnivores, feeding on sessile organisms such as sponge, bryozoan, hydrozoa, diatoms and various Cnidaria. Adult variation, distribution, depth, and habitat are discussed and a summary of distribution records are provided for unique species. Analysis of shell morphology indicates Akoya titanium is a synonymy of A. platinum. A review of museum material also suggests that C. splendens appears to be correctly placed as a synonym of C. supragranosm. A new species of Calliostoma from the most southern portion of the Californian marine province is described and illustrated.

Bathydrilus litoreus n. sp., from intertidal habitats of British Columbia and Washington, is distinguished from other members of the genus by the combination of possessing histologically bipartite atria, atrial ducts, bilobed glandular sacs about the penial setae, patches of glandular epithelium between the dorsal setal bundles, and thickened epidermal pads ventrally in X. Bathydrilus torosus n. sp., from the intertidal of southwest Vancouver Island, is the only known shallow-water species of Bathydrilus to lack modified penial setae; it lacks dorsal patches of glandular epithelium and thickened epidermal pads ventrally in X but does possess atrial ducts and histologically bipartite, very muscular atria. Both B. litoreus and B. torosus lack copulatory sacs and pseudopenes. These are the first species of the genus to be described from the Northeast Pacific.

The genus Opaliopsis from Brazil is revised based on three deep-water species. Opaliopsis atlantis (Clench & Turner, 1952) is confirmed as occurring in north-eastern and south-eastern localities. Opaliopsis opalina (Dall, 1927) is reported for the first time in the south-western Atlantic. A new species, Opaliopsis cearense, is described from the north-eastern Brazilian coast, and is distinguished by its large number of fine spiral cords per teleoconch whorl.

High Diversity

Leptogorgia christiae is a rarely collected new species found at 15–30 m depth at Roca Hacha, a rocky outcrop near Coiba Island characterized by its high diversity of octocorals. The branching pattern and combination of asymmetric blunt spindles, abundance of capstans, and a low occurrence of acute spindles are distinct characteristics of the new taxon. The new species is described, illustrated and compared to the other species of the genus reported from Pacific Panama; thus increasing the total of Leptogorgia species to 17, which encompasses over 70% of the shallow water species for the eastern Pacific.

Colonial Ascidians

Four shallow-water colonial ascidians of the genus Aplidium (Aplousobranhia: Polyclinidae) are identified in the material collected by SCUBA divers off the coast of East Kamchatka and Commander Islands. Three species from Kamchatka were previously known from this region but were wrongly identified and two of them (A. dissectum n. sp. and A. eborinum n. sp.) are now redescribed as new species. Aplidium redikorzevi nom nov. (for Amaroucium fragile Redikorzev, 1927) is recorded on Commander Islands first time from its original description.
