[Oh, a pokedex! Except...] ...Hm. Your pokedex appears to be out of date, so it might not be able to show it until you have the chance to get it upgraded. [But what's the likelihood of that happening...]

A bit of an unfortunate taste, I suppose. Otherwise, it would likely tell you that Galvantula is a bug and electric type Pokemon, and the evolved form of Joltiks. Also, they are currently exclusively found in the Unova region, at least since I last heard about them.
