Revision of Panaque (Panaque), with descriptions of three new species from the Amazon basin (Siluriformes, Loricariidae). Copeai 2010: 676–704.

Lujan, NK, M Hidalgo & DJ Stewart, 2010.

Abstract:
The Panaque nigrolineatus group (subgenus Panaque) is revised; three nominal species — P. cochliodon, P. nigrolineatus, and
P. suttonorum — are redescribed and three new species are described. Panaque armbrusteri, new species, is widespread in
the Tapajo΄s River and its tributaries in Brazil and is distinguished by having a supraoccipital hump, higher numbers of
jaw teeth and an ontogenetic increase in interpremaxillary and intermandibular tooth-row angles, relatively short
paired-fin spines, and dorsal margin of infraorbital six flared laterally. Panaque schaeferi, new species, is widespread in
main-channel habitats of the upper Amazon (Solimoes) River basin in Brazil and Peru; it is distinguished by having a
coloration consisting of dark or faded black spots evenly distributed on a pale gray to brown base, and by its large adult
body size ( 570 mm SL). Panaque titan, new species, is distributed in larger, lowland to piedmont rivers of the Napo
River basin in Ecuador, and is distinguished by having a postorbital pterotic region bulged beyond the ventral pterotic
margin, coloration consisting of irregular and widely spaced dark gray to brown stripes on light brown to tan base, and
large adult body size ( 390 mm SL). A relatively large pterotic, indicative of an enlarged gas bladder and gas bladder
capsule, and allometric increases in tooth number are hypothesized to be synapomorphies uniting members of the
subgenus Panaque.
