Thanks for your reply. Still, by surfing the internet I already have some CW numbers
Example CW174 and CW175 received their numbers in 2021.
More examples CW183 & CW184 & CW185 numbers in 2022.
I hope to be able to compile a complete list one day

Does anyone know the timeline when which corydoras CW number was assigned (year and month please) or where can I find it
Thanks
