CW106 was only recently imported in Australia in March 2021. It is a very hard to find species and harder to identify accurately. The species was wild caught and brought in from an exporter in Columbia.
As per the Aquarium Glaser Website: https://www.aquariumglaser.de/en/fish-archives/corydoras-cw-89-cw-91-cw-106-cw-107-2/
The long snouted counterpart of Corydoras sp. CW 107 is Corydoras sp. CW 106, which in turn should be of the same species as Corydoras sp. CW 89.
In both species the dorsal band running into the lower caudal lobes is very typical.
