    Abstract: Uma nova espécie de Corydoras do rio Tiquié, bacia do alto rio Negro, estado do Amazonas, Brasil, é descrita. Este táxon foi anteriormente citado na literatura aquarista como "Corydoras species 'Asher'", "Corydoras cf. reynoldsi" e "Corydoras aff. reynoldsi". O novo táxon pode ser distinguido de todos seus congêneres, exceto Corydoras reynoldsi e C. weitzmani, por seu padrão de colorido, que consiste em três grandes manchas pretas, a primeira ("máscara") na cabeça, através do olho; a segunda no tronco, no nível da nadadeira dorsal; e a terceira no tronco, no nível da nadadeira adiposa. Ele pode ser distinguido de Corydoras reynoldsi principalmente pelo desenvolvimento das manchas do tronco, e de C. weitzmani pela presença de uma mancha escura na porção dorsal das placas dorsolaterais, entre a nadadeira dorsal e a nadadeira adiposa, pela segunda mancha estender-se verticalmente da base da nadadeira adiposa até a base da nadadeira anal, e pela presença de quatro listras pretas na nadadeira caudal.

    Abstract: After 80 years of misidentifications, the analysis of the holotype of Corydoras arcuatus plus several non‐type specimens attributed to this species allowed its recognition and also revealed a new species, both sharing the following diagnostic features: a long, arched, continuous black stripe that runs parallel to the dorsal profile of the body and extends at least from the anterior margin of the first dorsolateral body plate to the posterior portion of caudal peduncle; absence of transverse black bars on caudal fin; infraorbital 2 in contact with sphenotic and compound pterotic. In addition to these features, C. arcuatus can be distinguished from congeners by having the posterior margin of both dorsal and pectoral spines with laminar serrations directed towards their origins. The new species can be additionally distinguished from its congeners by presenting the following combination of features: ventral surface of trunk entirely or partially covered by relatively large and coalescent platelets; absence of spots or blotches on dorsal fin; and posterior margin of both dorsal and pectoral spines with serrations directed towards their tips. Finally, an identification key to all arc‐striped species of Corydoras is provided.
