The Doublebar Seabream, Acanthopagrus bifasciatus (Forsskål 1775) with two conspicuous vertical black bars across the head has long been recognized as a distinctive species from the Red Sea and Western Indian Ocean. Two distinct colour patterns are associated with two allopatric populations except southern Oman and Somalia which appears to be a zone of overlap: a northern population (Red Sea, through Persian Gulf, to Pakistan) with dorsal and caudal fins immaculate yellow; and a southern population (east coast of Africa from the Horn of Africa to South Africa, Madagascar, and Mascarene Islands) having the dorsal fin with a wide black margin and caudal fin rear margin with a narrow black edge (and both black margins disappearing with growth in specimens over 30 cm SL). Both populations resulted in the two valid species: A. bifasciatus for the northern population and A. catenula (Lacepède 1801) for the southern population. Nominal species (junior synonyms) of the two species are discussed.

Ateleopus natalensis Regan 1921, described from off the coast of Natal, South Africa, has been regarded as a valid species. Regan (1921) stated that the difference between the two species is the condition of the lower-jaw teeth: toothless in A. natalensis vs. teeth present in Ateleopus japonicus Bleeker 1853. However, the condition of lower-jaw teeth of Ateleopus has been proved an unreliable character because the lower-jaw teeth are very deciduous. Although Regan (1921) also implied that the differences between the two species include several body proportions, my examination of two syntypes and non-type specimens of A. natalensis from the western Indian Ocean revealed their close similarity to the range of many specimens of A. japonicus. Ateleopus japonicus is redescribed as a senior synonym of A. natalensis.

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).

Twelve species from the Bay of Bengal, the Red Sea, the western Indian Ocean, and southwestern Australia are reclassified in Marmorofusus. These include: Murex undulatus Gmelin, 1791, a senior synonym of Murex variegatus Perry, 1811 and Fusus laticostatus Deshayes, 1831, formerly regarded as a junior synonym of Marmorofusus nicobaricus (Röding, 1798); Murex verrucosus Gmelin, 1791 (synonyms Fusus tuberculatus Anton, 1839 non Lamarck, 1822, F. marmoratus Philippi, 1846 and F. rudicostatus G.B. Sowerby II, 1880); F. polygonoides Lamarck, 1822 (synonym F. biangulatus Deshayes, 1833); F. tuberculatus (Lamarck, 1822) (synonyms Fusus indicus Anton, 1839, F. maculiferus Tapparone Canefri, 1875, Fusinus t. priscai Bozzetti, 2013 and F. t. fuscobandatus Bozzetti, 2017); Fusus philippii Jonas in Philippi, 1846, an earlier name for Fusus tessellatus G.B. Sowerby II, 1880 (other probable synonyms Fusus exilis Menke, 1843, non Conrad, 1832 and Fusinus dampieri Finlay, 1930, replacement name for F. exilis Menke); Fusus oblitus (Reeve, 1847) (synonym Fusus turrispictus Hedley, 1918); F. leptorhynchus Tapparone Canefri, 1875 (synonym F. subquadratus G.B. Sowerby II, 1880), Fusinus vercoi Snyder, 2004; F. wellsi Snyder, 2004; F. brianoi Bozzetti, 2006; F. verbinneni Snyder, 2006; and F. bishopi Petuch & Berschauer, 2017. Fusus toreuma Deshayes, 1843, sometimes misidentified as M. tuberculatus, is a member of the Fusinus colus (Linnaeus, 1758) species group.

Chrysaora (Pèron & Lesueur 1810) is the most diverse genus within Discomedusae, and 15 valid species are currently recognised, with many others not formally described. Since Chrysaora fulgida (Reynaud 1830) was first recognised as occurring off the south west (SW) coast off South Africa, the species has been variously synonymised with Chrysaora hysoscella (Linnaeus 1767) and Chrysaora africana (Vanhöffen 1902). Using DNA evidence alongside multivariate tools to analyse quantitative morphometric and meristic data, as well as information from the cnidome, we unambiguously separate C. fulgida from C. hysoscella; we resurrect C. africana as a valid species and recognise a new species, Chrysaora agulhensis sp. nov. Full descriptions of C. fulgida, C. africana and C. agulhensis sp. nov. are provided. The species have different geographical patterns of distribution around the region, with restricted areas of overlap: C. agulhensis sp. nov. is found along the southern coast of South Africa and over the Agulhas Bank, C. fulgida extends from Cape Point in South Africa to southern Angola, and C. africana can be found from southern Namibia northwards to the Gulf of Guinea. The species can be readily separated in the field by a combination of tentacle/lappet number and shape, colour patterns and the form of the oral arms.

The stinger genus Inimicus Jordan & Starks, 1904 (family Synanceiidae), distributed in the Indo-West Pacific, is characterized by having two free pectoral-fin rays. Examination of the original descriptions and 420 specimens, including all available type specimens, of the genus resulted in the recognition of nine valid species: Inimicus brachyrhynchus (Bleeker, 1874) (recorded from Hong Kong and Singapore), I. caledonicus (Sauvage, 1878) (distributed in Andaman Sea and western Pacific Ocean), I. cuvieri (Gray, 1835) (Andaman Sea and western Pacific Ocean), I. didactylus (Pallas, 1769) (western Pacific), I. filamentosus (Cuvier, 1829) (western Indian Ocean), I. gruzovi Mandrytsa, 1991 (Coral Sea), I. japonicus (Cuvier, 1829) (East Asia), I. sinensis (Valenciennes, 1833) (eastern Indian and western Pacific oceans), and I. smirnovi Mandrytsa, 1990 (southwestern Pacific Ocean). Inimicus joubini (Chevey, 1927), previously considered a valid species, is herein regarded as a junior synonym of I. japonicus. Another 10 nominal species are confirmed to be synonymized with the nine species. A revised diagnosis for each species and a key to all the species are provided.

In Madagascan waters, both Tetraclita rufotincta Pilsbry 1916 and T. africana Ren 1989 have been reported. Tetraclita rufotincta is more widely distributed than T. africana, extending to the western Indian Ocean and east Africa. Tetraclita africana is reported from Madagascar and no further distribution record has been made apart from its type locality. Both species have pink parietes and are similar in size, which could lead to identification confusion. In this study, we revealed that T. africana differed from T. rufotincta in having multicuspidate setae on cirrus III, a feature that can be observed with both light microscopy and SEM. Additionally, the tergum of T. africana has a rounded spur and a larger basi-scutal angle than that of T. rufotincta. However, since the name Tetraclita africana has been pre-occupied under the name Tesseropora (Tetraclita) wireni africana Nilsson-Cantell, 1932, we, therefore, propose herein a replacement name, Tetraclita reni nom. nov. Based on museum specimens examined, Tetraclita reni nom. nov. is present in northeastern and southern Madagascar and Mauritius but absent from Yemen, Kenya, South Africa, Aldabra and northwestern Madagascar, suggesting the distribution of T. reni nom. nov. could be confined to the south and northeast of Madagascar and adjacent waters.

Abstract Litsea glutinosa belongs to the family Lauraceae. It is a small- to medium-sized tree, 3-20 m tall, semi-evergreen, and fast-growing dioecious (Chowdhury et al., 2008; Ramana and Raju, 2019). It is native to India, South China to Malaysia, Australia and the western Pacific islands, and introduced and established in South Africa, the western Indian Ocean, and the south-western Pacific (New Caledonia), Mauritius and other tropical regions (Dassanayake, 1995). It has been introduced as a crop (Vos, 2004) and as an ornamental in tropical countries (EPPO, 2019). It has escaped from cultivation and is naturalized in some of the introduced areas. L. glutinosa has many uses in its area of origin as well as in some of its areas of introduction (ISSG, 2015). It is used principally as a binder for tablet formulations, and in the incense stick industry (Ramana and Raju, 2017).L. glutinosa is considered invasive in South Africa, where it is declared an invader plant (Henderson, 2001) and in the Indian Ocean (MacDonald et al., 1991; ISSG, 2015; PIER, 2019) on the islands of Mauritius (Mauritius Island and Rodrigues Island) (PIER, 2019) and Mayotte (Vos, 2004; ISSG, 2015; PIER, 2019). Jacq et al. (2005) do not consider L. glutinosa to be invasive globally, and ISSG (2015) considers it a small tree with high invasion potential, displacing native plant species in disturbed environments, although there is no evidence yet of its impact. It is classified by the IUCN (2019) as a species of Least Concern.
