Corydoras tukano, a new species of corydoradine
catfishfrom the Rio Tiquié, upper Rio Negro basin,
A Summary by Allan James
his is the new name given to Corydoras
sp. "Asher" or sometimes known as Corydoras
cf. reynoldsi. This Corydoras has
been around in the trade from about 1997 and has
just been named in a new paper by Marcelo
R. Britto of Departamento de Vertebrados,
Museu Nacional da Universidade Federal do Rio de
Janeiro Brazil, and Flávio
C. T. Lima of the Museu de Zoologia
da Universidade de São Paulo Brazil.
The differences are mainly the size and positions
of the blotches on the body between Corydoras
reynoldsi and the new Corydoras tukano.
You can see these marked differences on Factsheet
51 from September 2000.
In this paper Corydoras weitzmani is also
mentioned as similar with the differences cited
as C. tukano having a dusky saddle between
the dorsal and adipose fins, the second trunk blotch
extending vertically from the adipose fin base to
the anal fin base and also the presence of four
stripes in the caudal fin.
