Two new amazonian species of ancistrus with vestigial adipose fin, with an appraisal on adipose fin loss in neotropical armoured catfishes (Teleostei: Loricariidae)
Two new species of Ancistrus are described from Amazon basin: A. krenakarore from rio Itapacura, a tributary of the right margin of the lower rio Tapajós drainage; and A. karajas from small headwater streams of rio Parauape- bas, a tributary of left margin of lower rio Tocantins drainage, both from...

The two new species differ from all congeners except A. jataiensis, A. parecis, A. reisi, A. tolima, A. tombador, A. verecundus and A. veri- caucanus by the absense or vestigial adipose fin (vs. presence of a fully-developed fin).
