Pelteobagrus/Pseudobagrus

Every East Asian bagrid in the Cat-eLog is Pseudobagrus. WHile this is not necessarily set in stone, there are some that have more often been placed in Pelteobagrus.
The systematics of the two groups are in a mess, and it's possible that they are all one genus.
However, I think to avoid confusion, we should follow current scientific literature and split them up.

Pseudobagrus longirostris
Pseudobagrus nudiceps
Pseudobagrus sp.
Pseudobagrus taiwanensis
Pseudobagrus trilineatus

OK, which ones are affected? Also, could you come up with a paragraph explaining the split and I will put this in the ID notes.

Pseudobagrus longirostris: Pelteobagrus
Pseudobagrus nudiceps: Pelteobagrus
Pseudobagrus sp.: Pelteobagrus, this is P. nitidus, I think.
Pseudobagrus taiwanensis : Pseudobagrus
Pseudobagrus trilineatus: Pseudobagrus

Explanatory paragraph to follow...

The genera Pelteobagrus and Pseudobagrus form a monophyletic group, but the monophyly of the two genera are uncertain. Traditionally, members of the genus Pelteobagrus have been distinguished by their forked caudal fins (vs. truncate/emarginate caudal fins in Pseudobagrus). This convention is still largely used in current literature and is adhered to here. There are some Chinese species assigned to the genus Leiocassis (longirostris, crassilabris, tenuifurcatus, virgatus and argentivittatus), but have been tentatively placed in Pseudobagrus by Mo (1991).

There. How's that?

PS. I might add that P. virgatus is an attractive, small species (with a color pattern faintly reminescent of Hyalobagrus) which should be a popular aquarium fish (but isn't).

The html tags in the Cat-eLog for this are not set properly.
