- Description: Two genera of Squirrelfishes of the subfamily Holocentrinae are found in the Indo-Pacific region: Neoniphon (Flammeo of recent authors) and Sargocentron (Adioryx of most recent authors). A total of 19 species of these two genera occur in the Indian Ocean west of the southern tip of India: Neoniphon argenteus, N. aurolineatus (Flammeo scythrops Jordan & Evermann and Holocentrus anjouanae Fourmanoir are junior synonyms), N. opercularis, N. aurolineatus, Sargocentron caudimaculatum, S. diadema, S. ittodai (first records for the Red Sea and western Indian Ocean), S. macrosquamis (recently described from the Red Sea and Amirante Group, Seychelles, the range here extended to Kenya, Mozambique, Mauritius, and the Chagos Archipelago), S. melanospilos (usually misidentified as cornutum which is known only from the Indo-Malayan region), S. microstoma (known in the region only from Maldive Islands and Astove Island), S. praslin (usually not distinguished by authors from S. rubrum; Holocentrum marginatum Cuvier is a synonym), S. punctatissimum (has priority over lacteoguttatum due to selection by first revisor, Bleeker, 1873), S. rubrum, S. seychellense (an insular western Indian Ocean species), S. spiniferum (Holocentrum melanotopte- rus Bleeker is a junior synonym), S. tiere (Holocentrum elongatum Steindachner is a junior synonym), S. tiereoides (a new western Indian Ocean record), S. violaceum, and a new species, S. inaequalis (closely allied to macrosquamis Go- lani, 1984, differing in variable Spination of preopercle, modally one fewer pectoral ray, fewer average number of lateral-line scales and a more elongate body). S. inaequalis is described from a total of 7 specimens from the Chagos Archipelago, Seychelles and Comoro Islands. S. melanospilos is recorded for the first time from the Red Sea where it appears to be subspecifically distinct from populations elsewhere in the Indo-Pacific region (no subspecific name proposed). Holocentrum macropus Gunther, allegedly collected at Mauritius, is a misidentification of the Atlantic Holocentrus ascensionis (Osbeck). A lectotype is selected for S. microstoma. Neotypes are designated for S. praslin and S. rubrum. Colour photographs of fresh specimens of all of the species except S. macrosquamis are presented. , Rhodes University Libraries (Digitisation)

The fishes of the Okavango drainage system in Angola, South West Africa and Botswana: taxonomy and distribution

- Description: The publication of a new phase of research on the fishes of the Okavango drainage starts with this account which gives the valid names and broad distribution patterns of all species known from the system. Eighty species and subspecies are recognised, of which at least two (Parakneria fortuita Penrith; Serranochromis gracilis Greenwood) are endemic. Notes on early collections, synonymy, taxonomic status and distribution are given. New synonyms are recognized under Aplocheilichthys hutereaui (A. schalleri), Aplocheilichthys johnstoni (Haplochilus carlislei) and Ctenopoma multispinis (Ctenopoma machadoi) respectively. Recently published taxonomic changes are incorporated including two genera (Mesobola and Afromastacembelus), a species Serranochromis (Sargochromis) gracilis and the re-allocated Amphilius uranoscopus. The Zambezian Hemichromis species is re-identified as H. elongatus. A number of unresolved taxonomic problems are pointed out and certain dubious records are excluded from the checklist. The Okavango has a diverse fish fauna with tropical affinities. Many fish species are poorly studied. Man-induced threats to the continued natural functioning of this complex and dynamic system, especially large-scale water abstraction, overgrazing, deforestation and biocide spraying to eliminate tsetse fly, make it imperative that studies on the nature and role of the fishes are continued. , Rhodes University Libraries (Digitisation)
