<p>Pangasiidae are economically important riverine catfishes generally occurring in freshwater from the Indian subcontinent to the Indonesian Archipelago. Morphologically, they are recognized by a laterally compressed body, two pairs of barbels, a short dorsal fin with two spines, a well developed adipose fin, a long anal fin, and a strong pectoral spine. The systematics of this family are still poorly known. Consequently, the lack of this basic information is a great barrier in understanding the biology and hence the study of the aquaculture potential of species, the improvement of their seed production and growth performance. Objectives of the study are to present all species and genera of pangasiid catfishes of Indonesia including their distribution and detailed identification.</p><p> </p><p><strong>Abstrak</strong></p><p>Kelompok ikan pangasius atau pangasiidae merupakan jenis penting ikan &amp;ldquo;catfish&amp;rdquo; (bersungut) yang hidup di air tawar dan tersebar dari daratan India hingga kepulauan Indonesia.

<p>Pangasiids are economically important riverine catfishes generally residing in freshwater from the Indian subcontinent to the Indonesian Archipelago. The systematics of this family are still poorly known. Consequently, lack of such basic information impedes the understanding of the biology of the Pangasiids and the study of their aquaculture potential as well as improvement of seed production and growth performance. The objectives of the present study are to clarify phylogeny of this family based on a biometric analysis and molecular evidence using 12S ribosomal mtDNA on the total of 1070 specimens. The study revealed that 28 species are recognised as valid in Pangasiidae. Four genera are also recognized as Helicophagus Bleeker 1858, Pangasianodon Chevey 1930, Pteropangasius Fowler 1937, and Pangasius Valenciennes 1840 instead of two as reported by previous workers. The phylogenetic analysis demonstrated the recognised genera, and genetic relationships among taxa. Overall, trees from the different analyses show similar topologies and confirm the hypothesis derived from geological history, palaeontology, and similar models in other taxa of fishes from the same area. The oldest genus may already have existed when the Asian mainland was still connected to the islands in the southern part about 20 million years ago.</p>

ABSTRACT The species Rhamdia branneri Haseman, 1911 and the subspecies Rhamdia branneri voulezi Haseman, 1911 from rio Iguaçu are currently recognized as synonyms of Rhamdia quelen (Quoy & Gaimard, 1824). However, recent karyotype and ecomorphology studies distinguish R. branneri and R. voulezi as different species. Examination of Rhamdia populations from rio Iguaçu, including type specimens, together with other congeners from rio Tibagi, allowed to properly reexamine the situation of these Haseman's taxa and references given to Rhamdia in the Iguaçu. The species R. branneri and R. voulezi have strong serrae with large basis on both margins of the pectoral-fin spine, uncommon in the remaining species of Rhamdia and different from the fine serrate margins of the pectoral spine of R. quelen ; a regular dorsal profile, slightly curved between supraoccipital and dorsal fin; with dorsal dark-brown or light-gray coloration along body, abdomen pale, without profuse small black spots, common in populations of the upper Paraná species and the type-material of R. quelen . Also the following morphometric characters discriminate these species: Rhamdia voulezi , adipose fin elongate; smaller distance between dorsal and adipose fin; smaller length between adipose fin to base of caudal fin and smaller distance from posterior margin of eye to opercular border. Rhamdia branneri , larger distance from dorsal and adipose fins; deeper caudal peduncle; higher trunk depth in the vertical distance through adipose, between pelvic and anal fins; larger scapular bridge; shorter maxillary barbel; shorter external mental barbel; shorter interorbital distance; shorter length of dorsal fin basis and shorter adipose-fin base length. A PCA between the populations of Rhamdia from Iguaçu and a population from rio Tibagi, upper Paraná basin, discriminates the population from Tibagi on basis of dorsal to adipose fin distance, dorsal-fin spine length, maxillary barbel length, eye diameter, and pectoral-fin spine length. This morphometric study allied to the karyotype known differences suggest R. branneri and R. voulezi as valid species. The complex state of R. quelen with the neotype recently designated from rio Samiria recommend new studies on basis of molecular genetics and provision of the names R. branneri and R. voulezi in the Iguaçu basin.

The presence of the sisorid catfish genus Erethistoides in Myanmar, represented by three new species, is recorded for thefirst time. This discovery from the Irrawaddy and Sittang river drainages from central Myanmar and the Ann ChaungRiver drainage in western Myanmar extends the documented range of the genus beyond the Ganges/Brahmaputra Riverbasin. Erethistoides longispinis is distinguished from congeners in having the following unique combination ofcharacters: length of the dorsal-fin spine 24–27% SL, length of the pectoral-fin spine 29–35% SL, and absence ofproximally-directed serrations on the anterior edge of the pectoral spine. Erethistoides luteolus differs from congeners inhaving the following combination of characters: yellow base color of the body, body with distinct bands, vertebrae 30,premaxillary tooth band partially exposed when the mouth is closed, length of the dorsal-fin spine 14–15% SL, length ofthe pectoral-fin spine 21–24% SL, absence of proximally-directed serrations on the anterior edge of the pectoral spine,length of the adipose-fin base 16–17% SL, length of the caudal peduncle 22–25% SL and depth of the caudal peduncle 6–7% SL. Erethistoides vesculus is distinguished from congeners in having the following combination of characters: creambase color of the body, body with distinct bands, vertebrae 30, premaxillary tooth band partially exposed when the mouthis closed, length of the dorsal-fin spine 15% SL, length of the pectoral-fin spine 22–23% SL, absence of proximally-directed serrations on the anterior edge of the pectoral spine, length of the adipose-fin base 14–15% SL, length of the caudal peduncle 19–21% SL and depth of the caudal peduncle 4–5% SL.

Bagarius vegrandis, new species, is described from the Chao Phraya and Mekong river drainages. It differs from congeners in having a small maximum body size (to 220 mm SL vs. 520–1400 mm SL) and the adipose-fin origin markedly posterior to (vs. at vertical through or very slightly posterior to) the anal-fin origin. It further differs from congeners in having the following unique combination of characters: ovoid unculiferous plaques on dorsal surface of head, lateral margin of frontal not significantly deflected dorsally, eye diameter 11–15% HL, interorbital distance 23–28% HL, head width 18.3–22.3% SL, head depth 11.1–14.1% SL, filamentous extensions to first pectoral-fin element reaching to anus, dorsal spine width 10.6–13.9 times in its length, body depth at anus 8.7–12.0% SL, neural spines of the 4–6 vertebrae immediately anterior to adipose fin distally flattened but not forming series of prominent bumps along dorsal midline, length of adipose-fin base 10.8–13.0% SL, caudal-peduncle length 19.0–22.4% SL, caudal-peduncle depth 3.2–4.2% SL, 19–20 preanal vertebrae, and 39–40 total vertebrae. Bagarius bagarius (Hamilton, 1822) is demonstrated to be a species restricted to the Indian subcontinent (with Bagrus yarrelli Sykes, 1839, Pimelodus platespogon Valenciennes, in Jacquemont, 1839 and Pimelodus carnaticus Jerdon, 1849 as junior subjective synonyms) and Bagarius lica Volz, 1903 resurrected from synonymy with B. yarrelli as a valid species from Southeast Asia.
