8EDT

As the double of 4edt, harmonically, it is analogous to 10edo in that the harmonic chain is doubled. However, doing so does not make it a schismatic temperament like 10edo, because the full 3:5:7 triad is already present in 4edt. In any case, as a multiple of 4edt, I will say it is the widest variety of "Black-Extraterrestrial-Tree" temperament.

What it does introduce are flat pseudooctaves and sharp 3:2's, making it related to 5edo melodically.
