Well, I'm not sure if this counts "subverted", but in the world I've made for my fantasy series, I have Faeries and Pixies listed to two different beings - though technically, the Pixies are a sub-category of Faeries. I have it so that Faeries are only female, and tend to have lighter, brighter, more cheerful abilities and personalities, while Pixies can be male or female, have shorter hair and sharper features, and tend to have somewhat darker powers. Also, I have two different types of sirens - the mermaid sirens and the bird sirens, modeled after the original Greek sirens. The mermaid sirens are an extremist group of mermaids who hate humans for polluting their waters and use their voices to drown as many as possible. The bird sirens are shifters who can switch between human and bird forms, but don't specifically belong to either species, and use their songs for their own amusement. They are neither good nor bad, but have been known to enchant any human males they find interesting.
