A new species of suckermouth armored catfish, Pseudancistrus kwinti

Abstract
A new species of suckermouth armored catfish, Pseudancistrus kwinti, is described from the Coppename River, Suriname. It can be diagnosed from all other described Pseudancistrus by the following combination of characters: dentary papillae absent, mid-dorsal plate row complete, coloration mottled or with bars, hypertrophied odontodes along edge of snout, and weakly evertible cheek plates. It is only known from the Coppename River drainage within the Central Suriname Nature Reserve, a United Nations World Heritage Site, and one of the most pristine environments remaining on the planet. Mining, increased fishing pressure, and tourism threaten to change the region.
