Scientific Name

Corydoras amapaensis Nijssen, 1972 - add this species to your "My Cats" page.

Amapa State Cory

Type Locality

Cachoera Creek at right bank of Rio Amapari, 4 km downstream of Casa do 7, Amapa, Brazil.

Etymology

Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. From Amapa, the state in Brazil where the species was found. Latin ensis denoting a place, locality or country.

Identification

Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras. The colour pattern of this species varies considerably throughout its range and, because of this fact, it is often confused with the following species. C. septentrionalis originating from Venezuela, C. simulatus originating from Colombia and both C. treitlii and C. solox which were described from Brazil.
C. amapaensis differs from all but C. septentrionalis by the presence of a third pair of rictal barbels - see the catfish of the month article for more info. and pictures.
There is no easy way to distinguish C. amapaensis from C. septentrionalis, the former attain a slightly larger adult size and have a more rugged appearance than the latter. Although as youngsters they both have a light banding in their caudal fins, adult C. amapaensis have clear caudal fins.

Sexing

As with all Corys, the female is larger, plumper and has rounded pelvic fins.
