Etymology: Pseudolithoxus: Greek, pseudes = false + Greek, lithos = stone + Greek, oxys = sharp;  kinja: Named for the Waimiri-Atroari indigenous people, the Kinja people inhabiting areas surrounding the rio Uatuma and part of the rio Negro in the states of Amazonas and Roraima, Brazil. 'Kinja' ('true people') pays homage to this brave people who survived three attempts of genocide in the last century, and survive and thrive today in their protected area; noun in apposition..

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 2; 背的軟條 (總數): 7; 脊椎骨: 28. This species is distinguished from its congeners by the following characters: a colour pattern of large pale spots on a dark background (vs. pale bands on a dark background in P. kelsorum, P. tigris; small pale dots on a dark background in P. anthrax, P. nicoi; dark spots on a lighter background in P. dumus); differs further from P. anthrax, P. nicoi by having dark bands on the caudal fin (vs. none) and by the cleithral width 30.0-33.5% SL (vs. 27.2-30.5% in P. anthrax and 27.0-28.6% in P. nicoi (Ref. 119352).

生物學特性     字彙 (例如 epibenthic)

Collected in shallow (depth <1.5 m), fast-flowing water over a substrate of eroded bedrock, living among narrow cracks between rocks, and were abundant at the sampling site. However, this type of habitat was not frequently encountered on the lower Nhamunda, and the species was not found associated with more common woody-debris sites, or rocky sites lacking any appreciable water current. Water temperature 28.3C and conductivity 6 mS/cm. Syntopic fishes encountered during the night survey were species of Leporinus, Symphysodon, Cichla, Pimelodella, Tatia, Dekeyseria, Peckoltia, Lasiancistrus, and this species was the dominant loricariid in this habitat (Ref. 119352).

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
