- Description: From Conclusion: During her remarkable scientific career, Margaret Smith has progressed from lecturer to technician, artist and taxonomist, and now enters a new phase in retirement as the senior editor of the revision of her husband’s book ‘The Sea Fishes of Southern Africa’. Up until the end of 1981, she had co-authored three books, edited three books and authored or co-authored 35 scientific papers and numerous popular articles. She had produced about two thousand colour and black and white illustrations of the fishes of southern Africa and the Western Indian Ocean. Four fish species have been named for her — Simochromis margaretae from Lake Tanganyika, Pseudocheilinus margaretae from Aldabra Island, Canthigaster smithae and Chlidichthys smithae from Mauritius and Trachurus margaretae from Durban. She has established a network of collaborating ichthyologists which is probably unique and which has resulted in the Ichthyology Institute in Grahamstown becoming a mecca for researchers in the field. Her infectious enthusiasm for fishes has also inspired a generation of anglers, naturalists, students, scholars and, especially, children in South Africa and abroad. We all salute this great lady, an accomplished musician, mother, artist, scientist, patriot, humanitarian, and above all, a humble and generous friend — Margaret Mary Smith.

Pteropsaron heemstrai and Osopsaron natalensis (Perciformes: Percophidae), new fish species from South Africa, with comments on Squamicreedia obtusa from Australia and on the classification of the subfamily Hemerocoetinae

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 25 , Two new species of percophid fishes are described from off Natal, South Africa, Pteropsaron heemstrai from two specimens dredged at 143 m and Osopsaron natalensis from three specimens dredged at 100 m. This is the first record of a member of the subfamily Hemerocoetinae from the western Indian Ocean. The two new species belong to the lineage of closely related genera Acanthaphrites Gunther, Pteropsaron Jordan and Snyder, Osopsaron Jordan and Starks, Spinapsaron Okamura and Kishida, and Branchiopsaron McKay. A specimen of Squamicreedia obtusa Rendahl, previously known only from the damaged holotype, is described from Western Australia. It is postulated that the genera Squamicreedia Rendahl, Enigmapercis Whitley (whose range is extended to Western Australia), and Matsubaraea Taki form a closely related group in Hemerocoetinae.

Problems of species definition in Lake Malawi cichlid fishes (Pisces: Cichlidae)

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 23 , The evolution of the cichlid species flock in Lake Malawi has taken place very rapidly and resulted in the proliferation of a large number of species many of which are similar to one another. This has given rise to a situation in which traditional methods of distinguishing species based on preserved specimens are often of limited value. There are many instances of different species having almost identical morphologies, of single populations of one species showing considerable morphological variation and of marked geographical intraspecific variation. Polymorphism is considered not to be as widespread as previously thought, and pronounced random intraspecific colour variation within a population is discounted. Sympatric sibling species may be distinguished by observing behavioural and habitat differences in the field, but no means has been devised for ascertaining whether morphologically and behaviourally similar allopatric forms are specifically distinct. Lack of access to fresh specimens and lack of information on distribution and habitat have resulted in numerous errors appearing in taxonomic works on Lake Malawi cichlids. Great care is needed when attempting scientific descriptions of cichlid species from the African Great Lakes, and it is suggested that such work be left to specialists with knowledge of living and fresh fish in these lakes.

The distribution and identification of mormyrid fishes in Malawi, with notes on the synonymy of Marcusenius nyasensis and M. livingstonii (Mormyriformes: Mormyridae)

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 24 , Electrofishing surveys throughout Malawi have increased the number of mormyrid species known to occur in the country, expanded known ranges of the species and cast doubts on some earlier records. The distribution of each of the eight recorded species is given, and a key is provided for the identification of the species. The available evidence suggests that Gnathonemus nyasensis Worthington, 1933 is a junior synonym of Marcusenius livingstonii (Boulenger, 1898) a species described from the Ruvuma River of Tanzania. Geological evidence supports fish distribution evidence that indicates links between Lake Malawi and East Coast Rivers. Some affinities are also noted between Lake Malawi and Upper Zambezi/Zaire faunas.

Plotonus nkunga, a new species of catfish from South Africa, with a redescription of Plotosus limbatus Valenciennes and key to the species of Plotosus (Siluriformes: Plotosidae)

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 22 , Plotosus nkunga sp. n., from the east coast of South Africa, possibly ranging as far north as Zanzibar, is most similar to Plotosus limbatus Valenciennes, from the coasts of India, Sri Lanka, Kenya and Aldabra. Plotosus nkunga differs most notably in having fewer total gill rakers on the anterior faces of the first two arches, 16 to 21 versus 20 to 25 first arch, 16 to 24 versus 23 to 27 second arch; in having modally one more precaudal vertebra and slight modal differences in number of ribs and branchiostegal rays; in the shapes of the mesethmoid and the parapophyses of the fourth and fifth centra of the anterior complex vertebra; in the length of the maxilla; and in certain body proportions. Descriptions, annotated synonymies and illustrations are given for both species. A key to the five known species of Plotosus is presented.

- Description: Fifteen species of the labrid fish genus Halichoeres occur in the western Indian Ocean (west of the southern tip of India): hortulanus (centiquadrus of many authors), scapularis, (ziczac is a synonym), marginatus (lamarii, ianthinus and virescens are synonyms), dussumieri (nigrescens of many authors; javanicus, dubius and dianthus are synonyms), pardaleocephalus (first western Indian Ocean record), hoevenii (vrolikii is a synonym), nebulosus (previously confused with margaritaceus which does not occur in the Indian Ocean), zeylonicus (bimaculatus of most authors is a synonym), lapillus, and six new species (stigmaticus, pelicieri, cosmetus, iridis, trispilus, and leucoxanthus). H. stigmaticus from the Persian Gulf is distinctive in having 28 lateral-line scales, 6 or 7 suborbital pores, and a U-shaped black mark on side above pectoral fin tips in males; H. pelicieri from Mauritius is a close relative of H. zeylonicus, differing chiefly in the colour of males (pelicieri with a broad blackish zone in dorsal fin and no large black spot on upper side); H. cosmetus, wide-ranging in the western Indian Ocean and a close relative of H. ornatissimus of the Pacific and Cocos-Keeling Islands, is alternately striped with bluish gray to green and salmon pink or yellow; H. iridis, also a species of the western Indian Ocean, has a dark brown body except for a red band along the back and an orange-yellow head with green bands; H. trispilus, known only from Mauritius and the Maldives, is pale pink with a diagonal row of three dark brown spots on upper caudal base and usually three black dots on back; H. leucoxanthus, known only from the Maldives, southwest Thailand and Java, is yellow dorsally and abruptly white on ventral half of body with a dark spot behind the eye, a black spot on upper caudal base, and three others in the dorsal fin. , Rhodes University Libraries (Digitisation)
