The taxonomy of the deep-water homolid crabs Moloha grandperrini Guinot & Richer de Forges, 1995 and M. alisae Guinot & Richer de Forges, 1995 is re-examined, and the types redescribed and figured. Moloha alisae is reported from South Africa for the first time. A new species with an inflated carapace, M. tumida sp. nov., is also described from southern India and compared with its closest congeners.

A New Species

Callogobius winterbottomi new species is described from the 33.8 mm SL holotype and two paratypes (32.2 mm SL and 22.9 mm SL) from the Comoros, Western Indian Ocean. It is distinguished from all other known Callogobius species by the following combination of characters: sensory pores absent, 23–26 scales in lateral series, and sensory papillae pre-opercular row not continuous with transverse opercular row. One additional specimen of Callogobius winterbottomi was located from South Africa. A new standardized naming system for Callogobius sensory papillae rows is presented for identification and clarification of character states among Callogobius species. The new species is tentatively placed among what we term the “sclateri group”, a clade including C. sclateri (Steindachner) and three other species that exhibit a modified female urogenital papilla with lateral distal flaps and elongate ctenii on the caudal peduncle scales. Callogobius tutuilae (Jordan & Seale) is removed from synonymy with C. sclateri because it has partially united pelvic fins (vs separate) and the preopercular sensory papillae row is continuous with the transverse opercular row (vs separate).

A New Species

Abstract Doflein (1904) accidentally transposed the figures for the third maxillipeds of two species of pinnotherid crabs he described, a mistake which has taxonomic consequences. The species he described, Pinnotheres villosissimus Doflein, 1904, from Sumatra, is here referred to its own genus, Trichobezoares n. gen. The specimen Doflein identified as “Pinnotheres sp.” from South Africa was referred to a new species, Pinnotheres dofleini by Lenz (in Lenz & Strunck, 1914) partly based on Doflein’s (1904) incorrect figure of the third maxilliped. To stabilize the taxonomy of this species, Doflein’s specimen is selected as the lectotype; fixing the species as a member of Afropinnotheres Manning, 1993. Pinnotheres pilumnoides Nobili, 1906 (Djibouti) was differentiated from the taxon T. villosissimus partially on differences in the third maxilliped. It is redescribed, figured and shown to be a second species of Trichobezoares. The correct authorship for the species established in Lenz & Strunck (1914) is also discussed.

Sesarmid crabs of the genus Karstarma Davie & Ng, 2007 are reported for the first time in the Western Indian Ocean: they were discovered in the lava tubes of the volcano ‘Piton de la Fournaise’, Réunion Island. A new species, morphologically similar to Karstarma jacksoni (Balss, 1934) from Christmas Island, Eastern Indian Ocean, is recognized and described. A redescription of K. jacksoni is also provided. A second species is recognized, but being represented in the collection by a single juvenile, it cannot be identified to species level until more collections are made in the lava tubes.

A New Species

An immaculate square-nosed acanthurid fish of the genus Naso, previously misidentified as N. tuberosus, is described as a new species, N. mcdadei. The species is widespread, but appears uncommon, being known from only 10 specimens and five underwater photographs. It is described from specimens from tropical eastern and western Australia, southern Indonesia, Mauritius, and Natal, South Africa. Its occurrence is confirmed from off western Sumatra, the Maldives, Chagos Archipelago and southern Taiwan by photographs. It differs from N. tuberosus (Lacèpede, 1801) and N. tonganus (Valenciennes, 1835) most notably through smaller, more numerous teeth and a generally uniform greyish colouration. The head, body and fins all lack numerous small dark spots that are variously present in the latter two species. In adults, it also differs through a squarish rather than rounded tuberosity on the snout, a shorter straighter nasal groove, lack of a discernible hump in the dorsal profile, smaller-scale tubercles, non-prominent jaws, and first rather than last dorsal spine longest.The species previously recognised as N. tuberosus is split into two closely related taxa, N. tonganus (Valenciennes) from the western Pacific and Indian Oceans and N. tuberosus Lac�pede from the central and western Indian Ocean. These species differ mainly in the size and shape of the nasal tuberosity, dorsal profile, body depth, and colouration.

A New Species

A new species of the copepod genus Tortanus (Atortus) (Copepoda: Calanoida), T. (A.) insularis, is described from the coastal region of Rodrigues Island, Mauritius, an isolated island in the south-western Indian Ocean. This new species can be assigned to an Indian faunal element, the recticauda species group, in the Indo-West Pacific recticauda species complex. It exhibits the closest relationship to T. (A.) recticauda recorded from the southern Red Sea and Arabian Gulf, rather than the closer distributed T. (A.) capensis, recorded from off South Africa.

A New Species

The taxonomy of the deep-water spider crabs of the genus Scyramathia A. Milne-Edwards, 1880, is revised and four extant species are recognised from the Atlantic and western Indian Ocean: S. carpenteri (Norman, in Thomson 1873) (type species), S. umbonata (Stimpson, 1871), S. hertwigi Doflein, in Chun 1900, and S. tenuipessp. nov.Scyramathia tenuipessp. nov. from the Mediterreanean is easily distinguished from its congeners by its slender and elongate ambulatory legs. All species are diagnosed and figured. The taxonomy of two allied genera from the Atlantic and Mediterranean, Rochinia A. Milne-Edwards, 1875, and Anamathia Smith, 1885, are also treated and their type species redescribed and figured.

A New Species

Platepistoma seani sp. nov. is described from deep water off KwaZulu-Natal Province, South Africa. It can be separatedfrom its nearest relative, Platepistoma guezei (Crosnier, 1976), by its thicker setal covering that completely hides the an-terolateral teeth from dorsal view, less well defined carapace regions, more spinous anterolateral and posterolateral cara-pace margins, sparser but more prominent dorsal carapace spines, more prominent spines on the carpus of the cheliped, and a relatively narrower male telson.
