Here's a challenge. What elementals would you associate with elements outside of the four classic Greek elements? What would you imagine to be a Solar Elemental, or a Wood Elemental, Metal Elemental, Ice Elemental? First, imagine. Then, try to evoke and see if what you call upon matches what you've imagined.

I associate foxes with the Solar Element, personally. Wolves with the Lunar Element. The Fair Folk with the Wood Element. Strangely, I imagine a Crane being linked to the Metal Element (don't ask me why, I have no idea).
