Etymology: Placocheilus: Greek, plax, plakos = a flat plate + Greek, cheilos = lip (Ref. 45335); dulongensis: The specific name, dulongensis, is an adjective that refers to the Dulong River, where the species occurs, and the suffix agrees in gender with the generic name Placocheilus (gender neuter).

Morphology | Morphometrics
soft rays: 8. Distinguished from all congeners by the combination of the following characters: absence of semicircular black mark on the middle of each caudal fin lobe; absence of black band across the dorsal fin; two pairs of barbels; lateral line with 39-40 scales (Ref. 93106).
Occurs in shallow, fast flowing and clear water along the banks of the main course and the tributaries of the Dulong River. The bottom consists of large boulders, cobbles, gravel, and little sand. The wet rocks are covered with many diatoms (Ref. 93106).

Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00312 - 0.01463), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
