Latinate nomenclature for one-and-a-half

[Mike Taylor <mike@indexdata.com>]

We are all familiar with Cope's genera Monoclonius ("one root") and
Diclonius ("two roots") -- but what would be the correct name for an
animals whose teeth each had one and a half roots?
Monoandahalfclonius, only in Latin?
