Etymology: Acantopsis: Greek, akantha = thorn + Greek, ops = similar (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce démersal; pH range: 6.0 - 6.5; dH range: ? - 10. Tropical; 25°C - 28°C (Ref. 1672)
Asia: Java, Borneo, Sumatra, and the Malay Peninsula as far north as southern Thailand. Reported from areas of Southeast Asia outside its range, including as Acantopsis. Choirorhynchos because of the lack of taxonomic resolution in Acantopsis.

Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 9 - 11; Vertèbres: 42 - 44. Acantopsis dialuzona is distinguished from all congeners by combination of the following characters: usually 3 pairs of labial barbels; well developed ocellus on upper margin of caudal-fin base; 0-1 row of large spots on side of head; absence of large black spots on dorsal or caudal fins; rarely black specks beneath midlateral row of black spots; dorsal fin usually with 10½ branched and pectoral fin with 10 rays; 11-17 dark saddles along dorsal midline; 7-13 black spots along side of body; 42-43 total vertebrae; and body depth 8.9-11.9% SL, body width 6.4-9.1% SL, caudal-peduncle length 12.5-16.2% SL (Ref. 116755).
Inhabits rivers where they feed on small animals in the bottom sediments. Occurs in swift, clear streams with sandy or gravelly bottom; also found in large rivers (Ref. 4832).
