There are 2 kinds of cichlids where the moniker Kribensis is used .
Pelamochromis pulcher, (Kribensis) a soft water, low pH cichlid from West Africa (Benin, Cameroon, and Nigeria)
If you are not concerned with a correct biotope, this species would work with soft water S American species such as Corys, and tetras.
I have found if you have hard water, with pH above 7.5, this species tend to bloat, and does not to well.
And the Rock Kribensis, Paralibidichromis savaugiei, is a cichlid from the higher pH waters of Lake Victoria (pH 7.5 and above)
This species may possibly work with smaller Central America cichlids, again, if a correct biotope is not a concern.
By the way, there are No Corys native to the hard, high pH waters of Central America.
There are some Corys from southern S America, places such as southern Brazil, Uruguay, and Argentina where the water is more neutral, and alkaline.
I have been able to keep these in the alkaline, higher pH waters when in Wisconsin,

I would not keep corys with more predatory cichlids though.
Most cichlids, being substrate dwelling species really have no need for other bottom dwellers in the same tank.
I just keep them together in keeping with the species from the same and correct riverine biotope.
