Etymology: Pseudoqolus: Pseudoqolus is a portmanteau of the Greek word pseudes (false) and the genus name Panaqolus, indicating that although this genus may look superficially like Panaqolus, such an appearance is false.; koko: The name koko is a Wayana Amerindian name meaning night, in reference to the dark coloration of the species, and in allusion to the similarly colored and named Panaqolus nocturnus. A noun in apposition (Ref. 90183).

形態学 | 形態計測学
背面の脊椎 (合計): 2; 背鰭 (合計): 7; 肛門の骨 1; 臀鰭: 5. This species is distinguished by its large and almost spoon-shaped teeth characteristic of Panaqolus but bifid instead of most generally unicuspid in congeners, and characterized by its specific barcode sequence (JF747003). Differs also from all other congeners except Panaqolus dentex and P. nocturnus by having a uniformly blackish-brown coloration (vs. banded pattern of coloration in P. purusiensis, P. gnomus, P. maccus, and P. changae; or spotted pattern of coloration in P. albomaculatus). It can be separated from Panaqolus dentex by having dark pigment on membrane and branched rays of all fins, as well as a smaller interorbital width (29.4-33.2% HL, mean 31.6, vs. 38.7), a shorter pectoral spine (29.8-31.3% HL, mean 30.3, vs. 34.8) and a greater caudal peduncle depth (12.0-13.4% SL, mean 12.9, vs. 10.8). It is readily distinguished from Panaqolus nocturnus by having larger eye (orbit length 18.8-20.8% HL vs. 13.7-15.9) (Ref. 90183).
Found in main river channel on a stony substrate at two meters depth (Ref. 90183). Collected together with the hypostomins Hemiancistrus medians, Peckoltia otali and Pseudancistrus barbatus, and with the loricariins Harttia guianensis, Loricaria cataphracta and Rineloricaria stewarti (Ref. 90183). The gut contents of one specimen consisted mostly of intact sponge fragments and spicules (Ref. 117193).
