New Pseudolithoxus

[Silurus]

Lujan, NK & JLO Birindelli, 2011. A new distinctively banded species of Pseudolithoxus (Siluriformes: Loricariidae) from the upper Orinoco River. Zootaxa 2941: 38–46.

Abstract

Pseudolithoxus kelsorum is described as a new species based on type material from the upper Orinoco in Amazonas State, Venezuela. Pseudolithoxus kelsorum is diagnosed from all other Pseudolithoxus by having dark brown to black base color with eight to 11 (usually nine) light yellow vertical or oblique transversal bands between orbits and caudal fin, bands wide and rarely but sometimes incomplete or contorted as swirls (vs. dark brown to black base color with 18 or more thin, light yellow, frequently contorted transversal bands between orbits and caudal fin in P. tigris; black base color with small white spots in P. anthrax and P. nicoi; and light brown base color with dark brown to black spots in P. dumus). Distributions of P. kelsorum and other Ancistrini taxa support the presence of a zoogeographic filter limiting fish distributions across a reach of the Orinoco River between the Ventuari-Orinoco confluence and the Maipures rapids.

I thought this fish was

L189

when I first saw the specimens a while back but I didn't really look at them closely. The extremely flattened body shape is reminiscent of L189 but the tail shape and color pattern is not exactly quite like L189 in the clog. I could be wrong about it being L189, though.

Actually, it looks like a good match with the DATZ original.

FWIW, it looks like HH agrees with me.
