Hmm... well, as the name Leptoceratops is formed entirely from Greek roots
including 'ops' [face] (the stem of which is 'opsi'), Mackovicky has
actually been the first to get it WRONG. When borrowed into Latin, the Greek
word 'ops' would normally become 'opsis' (e.g. synopsis, borrowed by English
via Latin), so I don't know why anyone has ever assumed the stem in
ceratopsian names was '-op'. 

There was a similar kind of kerfuffle in snake nomenclature because of
uncertainty about the correct grammatical stem of 'ophis' (Gr., snake);
there were families named with '-ophidae' (Wrong!), '-ophiidae', and just
once, '-opheidae' because Robert Hoffstetter discovered that in Attic Greek
the stem was actually 'ophe' (as in genitive opheos). For a brief period it
looked like the opheids were going to sweep all before them, till someone
pointed out that in other classical dialects 'ophi' was correct (Cannatella,
D. C. 1990. Ancient Greek and ophidian orthography. Journal of Herpetology
24(3):322-323.)  An unresolved question is whether we should use
Lapparentopheidae as Hoffstetter named it, or change it for consistency with
the numerous -ophiidae names (seeing as how he was operating under an
incorrect assumption that they were all wrong).

Cheers,
John
