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.

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.

Water Species

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.

Preliminary Phylogenetic Analysis

Two new species of tanaids were collected from colonization traps deployed in a shallow water, sandy habitat off Akajima, Nansei Islands. One new parapseudidaen, Parapseudes arenamans, and one new nototanaidaen genus and species, Paranesotanais longicephalus, are described herein. A preliminary phylogenetic analysis of the closest genera confirms the validity of the new genus and suggests a close affinity between the Leptocheliidae and Nototanaidae. Paranesotanais longicephalus was by far the most abundant species in the habitat. Parapseudes arenamans is faster in colonization of vacant substrate (opportunistic species), while being an inferior competitor to Paranesotanais longicephalus later in succession. A key to Nesotanais and Paranesotanais is provided.

Water Species

Heteroclinus argyrospilos, n. sp. is described as a new species from specimens sampled by sled and dredge in 55–100 m off South Australia and Western Australia. The species has a strongly compressed body and spatulate orbital tentacle similar to some shallow water species, particularly those of the Heteroclinus heptaeolus complex, which is characterized by having three segmented dorsal-fin rays, with the last two rays widely separate from the first ray. It is distinct from other Australian clinids in having two segmented dorsal-fin rays, well separated from the last dorsal-fin spine and a reduced lateral line on the body. It is known from a greater depth than other members of the genus.

Calcareous Ring

In this paper we describe a new genus and a new species of Chiridotidae based on specimens collected in shallow water off the South-eastern Brazilian coast. Gymnopipina ikamiaba gen. nov. et sp. nov. is characterized by the complete absence of dermal ossicles in the body, and it differs from the other ossicleless apodids in the number of tentacles and of Polian vesicles, and in the morphology of the calcareous ring. Although not formally tested with a phylogenetic framework, apodids have apparently lost their dermal ossicles multiple times. If these reversions hold true, Gymnopipina gen. nov. represents the fourth independent loss of dermal ossicles in the class Holothuroidea. An identification key to the Brazilian apodid species is also provided.

A New Species

The genus Prochyliza Walker is recorded for the first time from the Afrotropical Region. A new species, Prochyliza ignifera sp. nov., is described from the Indian Ocean islands of Aldabra and La Réunion. The status of this species as possibly the most primitive in the genus Prochyliza is hypothesised and discussed, raising some questions about the taxonomy and the zoogeographical origin of the group. The holotype of Piophila viridicollis Macquart from La Réunion was studied and it is instated as a subjective junior synonym of Piophila casei (Linnaeus), syn. nov.

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.

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.
