To anyone (HH?) who might know:
Is it true that the genus Parauchenipterus does no longer exist and that all previous members are now called Trachelyopterus??

According to CLOFFSCA, yes.

Thanks for your reply.
But what happens to the fish already in Trachelyopterus? There must have been some difference, otherwise fish wouldn't be divided into two genuses to start with, would they?

I think the differences are not enough to warrant dividing them into two genera.

Isn't it interesting, that everybody(?) uses CLOFFSCA as a revisionary paper, even it only lists names. There is to my knowledge not yet a paper published, which explains, why the differences in the two genera are now not big enough any more, as they used to be when both were established.
Anyhow is the splitting off in different genera an act which always had to be seen critically, to loose a genus might also mean to loose taxonomic manifested information on fish groups.
