The taxonomy of the catfish genus Silurichthys is revised, and eight species are now recognized. A neotype is designated for S. hasseltii. Two new species are described: S. gibbiceps from the Barito basin in southern Borneo and S. marmoratus from north-western Borneo. Silurichthys leucopodus Fowler, 1939, is considered a subjective junior synonym of S. schneideri Volz, 1904. The extent of the gape and the relative positions of the dorsal and pelvic fins show considerable infraspecific variation and are of little taxonomic value. The number of anal-fin rays is useful if used with other meristic data such as the number of vertebrae. Colour varies infraspecifically as individuals become paler and less mottled at night, but can still be used as a secondary character in separating some species. The head and caudal fin shapes are useful discriminating characters. Mature males are smaller than females and have prominent posterior serrae on the pectoral spine and articulated segments of the first pectoral-fin element. The shape and number of these serrae are also diagnostic for some species. 1998 The Fisheries Society of the British Isles

“…(1982: 10) noted that about two-thirds of Tasik Bera (ca 67%) was swamp forest with peat substrate; and three habitat types could be distinguished in the study site: Utricularia stands, Lepironia stands, and open water areas. Mizuno & Furtado (1982) did not indicate which species were collected from blackwaters. The presence of large numbers of submerged macrophytes in the study area (see Mizumo & Furtado, 1982) suggests that the study area had mainly dilute blackwater.…”

“…The presence of large numbers of submerged macrophytes in the study area (see Mizumo & Furtado, 1982) suggests that the study area had mainly dilute blackwater. Of the 95 species reported from Tasik Bera by Mizuno & Furtado (1982), only two, Sphaerichthys osphromenoides and Ompok leiacanthus, can be regarded as stenotopic acid blackwater species. They compared their species with those of Johnson (1967b) and noted that 11 species could be classified under his 'dilute blackwaters habitat' category.…”

“…There have been few direct studies on blackwater species. Mizuno & Furtado (1982) reported on an extensive ecological study of fishes in the swamp-lake of Tasik Bera in Pahang, which includes peat swamp forests with blackwaters (see also Lim et al, 1982;Shiraishi et al, 1972) but did not specify which species actually line in blackwaters (see discussion later). He (1968) commented that blackwaters were generally speciespoor in fishes.…”

Diversity and conservation of blackwater fishes in Peninsular Malaysia, particularly in the North Selangor peat swamp forest

One of the most extreme freshwater habitats in Peninsular Malaysia is the peat swamp forest, with dark-coloured and highly acidic waters. Surprisingly, little is known about blackwater fishes in Peninsular Malaysia. Until 1968, only 26 fish species were known from blackwaters throughout Peninsular Malaysia, of which only one can be regarded as stenotopic. A recent intensive survey of part of the North Selangor peat swamp forest yielded 47 species, of which 14 are probably stenotopic taxa. These include four undescribed species and several new records for western Peninsular Malaysia. These discoveries are significant in that they include the family Chaudhuriidae which until 1985, was not reported from Sundaic Southeast Asia, and the rare genus Encheloclarias which had not been encountered for over 50 years. The rapid rate of destruction of the peat swamp forest owing to development, forestry and agricultural activities must be halted or slowed significantly to enable the proper zoological surveys and studies to be conducted. Conservation plans and environmental impact assessments based on inadequate sampling and knowledge of species present is acutely dangerous. There are no longer substantial undisturbed blackwater peat swamp forests left in most of Peninsular Malaysia. Conservation of the remaining blackwater biotopes is critically important if extinction of many species, here regarded as economically valuable renewable resources, is to be prevented.
