I discovered that several of the EvoMon's names have parts that can be wiki'd, so I did a search for both Corallus and Biancamella.
I initially decided to search for Corallus because of the following thought: "Corallus... coral snake? But coral snakes are harmless, and the Corallus seems to be in the process of eating my head." Well, as it turns out, "corallus" has nothing to do with coral snakes and actually refers to tree boas, which are somewhat more dangerous, to say the least. So that's that, and not terribly surprising.
Next I did a search on Wikipedia for Biancamella, not really knowing what to expect, should I get results. I didn't, and was thus prompted to try Google, which I did. Google suggested the spelling "Biancabella," which I tried, and low and behold! a Wikipedia article.
It's...interesting, and I know not what to make of it in regard to the Biancamella, which is mysterious enough without the correlation to an Italian fairy tail. The names are too similar to be mere coincidence, but... well, see for yourself:
