I am not an expert, but we can still clarify a bit the situation saying that currently
the genera is commonly set to Haplochromis with in comment or parenthesis the old Greenwood generic name commonly based on specific fish attributes
here a set of examples:
Haplochromis (Enterochromis) "broken bar"
Haplochromis (Ptyochromis) sauvagei
Haplochromis (Lipochromis) melanopterus
Haplochromis (Paralabidochromis) "rock kribensis"
Some new genera from the 90's were described fully by Ole Seehausen,
are now fully introduced in the taxonomy and commonly used by everyone
samples :
Pundamilia nyererei
Litochromis rubripinnis
Mbipia Lutea
Neochromis rufocaudalis
Also some names are still available as before without any change in taxonomy
Platytaeniodus degeni
You can have a look at
