Nyasasaurus is some kind of "thecodontian" described as a primitive dinosaur 
in Alan Charig's doctoral dissertation around 1956. The description was never 
formally published; Charig evidently never got around to it. Take a look at 
White 1973's list of dinosaur genera (where the name is misspelled 
Nyasaurus). I think you'll find it there. There are a few other arhcosaur 
nomina nuda in Charig's dissertation: Teleocrater, Hypselorhachis, 
Pallisteria, and Mandasuchus (which was finally described in part 13 of the 
German Handbuch der Palaeoherpetologie). I think Huene got hold of the 
dissertation and used some of these names in his Palaeontologie und 
Phylogenie der niederen Tetrapoden in 1956 (have to check this).
