Resumen y Abstract escribió:As espécies típicas de focinho longo de Corydoras da bacia do río de La Plata foram revisadas, e a sinonímia proposta anteriormente de Corydoras ellisae foi corroborada. Corydoras areio e C. aurofrenatus são diagnosticadas de seus congêneres, excluindo aquelas da linhagem 1, pelas seguintes características: canal sensorial temporal no esfenótico com dois poros; placa dentária superior do arco branquial com três ou quatro séries de dentes; aba carnosa no canto da boca. Corydoras areio difere de todos os congêneres da linhagem 1 pelo infraorbital 2 com expansão laminar posterior relativamente mais ampla; ausência de grandes manchas de pigmentação preta no corpo e ausência de concentração conspícua de cromatóforos marrom-escuros ou pretos na porção anterior da nadadeira dorsal; presença de manchas laterais não alinhadas em série longitudinal. Corydoras aurofrenatus difere de todas as congêneres da linhagem 1 pela superfície ventral da cabeça e do tronco densamente coberta por pequenas plaquetas não coalescentes; porção média lateral com duas ou três manchas marrom-escuras ou pretas (abaixo da nadadeira dorsal, abaixo da base da nadadeira adiposa, e na base do pedúnculo caudal, difusa e variavelmente presente), manchas diminuindo de tamanho posterior
Lo mantendría simple, porque el artículo es muy extenso, pero muy interesante: Las Corydoras areio y Corydoras aurofrenatus, han tenido un estudio científico más profundo: morfología, biotopo, etc. Muchos detalles muy técnicos.
