Macromia irata is a species of dragonfly in the family Macromiidae.

Segment 2 has a pair of mid-dorsal diamond-shaped spots narrowly separated in the middle.

The ventral border of this segment is broadly yellow at base.

Segment 3 has a pair of mid-dorsal triangular spots at the basal side of jugal suture and a large triangular spot on each side at base.

[citation needed] It can be distinguished from other Macromia species by a characteristic twin diamond-shaped saddle-marking on segment 2.
