Supra-triangular space: in Anisoptera, an area just above the triangle, occupying nearly the same position as the quadrilateral of Zygoptera: hyper-trigonal space.
Suranal plate: the middle dorsal plate attached to the l0th abdominal segment of the male grasshoppers, above the anal opening: a supra- anal tergite of a caterpillar.
