Abstract Freshwater ecosystems are highly biodiverse 1 and important for livelihoods economic development 2 , but under substantial stress 3 . To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods 4,5 used to guide environmental policy 6 conservation prioritization 7 whereas recent proposals target setting freshwaters use abiotic factors 8–13 However,...
The species of Glyptothorax Sundaic Southeast Asia (Malay Peninsula, Sumatra, Borneo and Java) are revised in this study. A total 17 recognized, which six (G. amnestus, G. decussatus, famelicus, keluk, pictus stibaros) described as new here. lectotype is designated for platypogon. diagnosed by combinations color pattern, morphometry (with particular regard to the eye, head, body depth, caudal peduncle), dorsal-spine thoracic adhesive apparatus morphology.
A new species of glyptosternine catfish in the genus Exostoma is described this study. The species, E. ericinum, known from upper Dayingjiang (=Taping River) drainage southwestern China and distinguished congeners having an unique combination following characters: 42–44 vertebrae; parallel striae on anterolateral surfaces lips lower surface maxillary barbel; interorbital distance 26–31% HL; preanal length 67.7–70.5% SL; body depth at anus 10.4–12.0% SL (1.4–1.9 times caudal peduncle depth);...
We describe Olyra praestigiosa, a new anguilliform bagrid catfish, from the Brahmaputra River drainage in Bangladesh and northeastern India. The species differs congeners having following unique combination of characters: interorbital distance 30-37% HL; body depth at anus 6-9% SL; length adipose-fin base 99-16% adipose fin separate upper principal caudal-fin rays; post-adipose 15-18% 17-22 anal-fin caudal peduncle 14-19% 6-8% SL.
A new species of bagrid catfish in the genus Leiocassis is described from Mahakam River drainage eastern Borneo. rudicula, species, can be distinguished congeners having a unique combination of: distinct concavity at level orbit dorsolateral profile head; tip supraoccipital spine not reaching anterior nuchal plate element; smooth posterior margin dorsal spine; presence an irregular pale band on sides body between and adipose fins; anal fin with narrow brown across middle third fin;...
Glyptothorax forabilis, new species, and G. porrectus, are described from the Bolaven Plateau in southern Laos. Both species closely resemble laosensis, but can be distinguished it other Indochinese congeners by combinations of color pattern, morphometry (with particular regards to eye, body depth, caudal peduncle) thoracic adhesive apparatus morphology. endemic Plateau, have a very limited distribution threatened hydropower agricultural activities.
This study describes a new diminutive sisorid catfish from the upper reaches of Karnaphuli River drainage in northeastern India. The species can be distinguished congeners having combination of: length dorsal-fin spine 18.0–21.6% SL; 4–10 serrations on anterior edge dorsal spine; pectoral-fin 20.7–26.1% adipose-fin base 21.5–26.3% body depth at anus 12.3–15.9% caudal peduncle 7.5–9.8% 17.0–20.5% pale, y-shaped marking surface head; sides with pale yellowish patches and irregular bands.
A new species of Macrognathus the M. aculeatus group is described from Kahayan River drainage in southern Borneo, Kalimantan Tengah, Indonesia. kris, species, distinguished all Asian congeners having following unique combination characters: rim anterior nostril with two fimbriae and fimbrules; 43–45 rostral tooth plates; 24–25 dorsal spines; 46–55 dorsal-fin rays; 51–59 anal-fin 20–23 principal caudal-fin 76–78 total vertebrae; body depth at anus 11.8–15.9% SL; color pattern consisting light...
Bagarius vegrandis, new species, is described from the Chao Phraya and Mekong river drainages. It differs congeners in having a small maximum body size (to 220 mm SL vs. 520–1400 SL) adipose-fin origin markedly posterior to (vs. at vertical through or very slightly to) anal-fin origin. further following unique combination of characters: ovoid unculiferous plaques on dorsal surface head, lateral margin frontal not significantly deflected dorsally, eye diameter 11–15% HL, interorbital distance...
The identity of Clarias batrachus, a species hitherto thought to be widely distributed throughout South and Southeast Asia, is clarified by the designation neotype. neotype necessary because ambiguous data in Linnaeus' original description it fixes type locality Java. variability observed what currently recognized as C. batrachus discussed; morphological karyological indicate that four are confused under name batrachus.
Pterocryptis subrisa, a new species of silurid catfish from the Kaladan River drainage in northeastern India, is described this study. It can be distinguished congeners by unique combination following characters: supralabial fold extending posteriorly beyond vertical through posterior orbital margin; nearly circular eye; head length 17.6-19.6% SL; depth 10.6-11.9% dorsal-fin height 2.6-4.7% 2 rays; pectoral-fin 11.8-14.0% body at anus 14.4-16.7% caudal peduncle 6.8-8.5% 66-75 anal-fin...
This study describes Pterocryptis vorax, a new species of silurid catfish from the upper reaches Temburong River drainage in Brunei Darussalam, northern Borneo. vorax is distinguished congeners having unique combination following characters: rictal lobe ending at vertical posterior to orbital margin, deep lower jaw with more gently curved anteroventral color pattern densely distributed dark brown patches on flanks that coalesce form reticulate pattern, band caudal-fin base, 46–57 anal-fin...
We have recorded 54 species of non-native or alien freshwater fishes from 14 the 15 reservoirs in Singapore. 31 these are established and breeding reservoirs. Three (Mystus wolffii, Amphilophus citrinellum, Satanoperca jurupari) represent new records for
Summary 1. Identifying the ecological and life‐history correlates of local extinction may elucidate mechanisms by which species traits environment interact to result in extinctions, will help predict target extinction‐prone for inclusion conservation programmes. Freshwater habitats are known be highly threatened Southeast Asia but among tropical freshwater fish remains unclear. 2. To bridge this knowledge gap, we examined Singapore using machine learning methods: conditional inference trees...
