Abstract:
Hemiancistrus pankimpuju, new species, and Panaque bathyphilus, new species, are described from the main channel
of the upper (Marafton) and middle (Solimoes) Amazon River, respectively. Both species are diagnosed by having
a nearly white body, long filamentous extensions of both simple caudal-fin rays, small eyes, absence of an iris
operculum and unique combinations of morphometries. The coloration and morphology of these species, unique
within Loricariidae, are hypothesized to be apomorphies associated with life in the dark, turbid depths of the
Amazon mainstem. Extreme elongation of the caudal filaments in these and a variety of other main channel
catfishes is hypothesized to have a mechanosensory function associated with predator detection.
