Etymology: Acantopsis: Greek, akantha = thorn + Greek, ops = similar (Ref. 45335); dinema: Dervied from the from Latin di (meaning two) and nema (meaning for thread), in reference to the usual presence of two pairs of labial barbels in this species.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Asia: tributaries of the Mekong River draining the Khorat Plateau and Mekong Delta ecoregions in Thailand, Laos, and Cambodia; and Songkhram River in eastern Thailand to the Prek Thnot River south of Phnom Penh, Cambodia.

Morphology | Morphometrics
Vertebrae: 41 - 42. Acantopsis dinema is distinguished from all congeners by the combination of the following characters: absence of large spots on side of head; many black specks beneath midlateral row of black spots from head to caudal fin; 2 pairs of labial barbels; absence of distinct small black spot on upper margin of caudal-fin base; absence of large black spots on dorsal or caudal fins; dorsal fin usually with 10½ branched rays and pectoral fin with 10 rays; 8-17 dark saddles along dorsal midline; 6-12 black spots along side of body; 41-42 total vertebrae; and body depth 12.0-14.5% SL, body width 8.0-10.3% SL, caudal-peduncle length 12.1-14.3% SL (Ref. 116755).

= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00245 - 0.01178), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100) .
