Rather large damselflies with a mainly red abdomen, no postocular spots, black legs and dark pterostigmas. Some females lack any red, being black marked with yellow. The thorax markings are unique: the antehumeral stripe is an (often red) exclamation mark that crosses the humeral suture (as its name indicates, this stripe is normally entirely anterior to that suture). Red specimens can be confused only with Ceriagrion species, but differ by leg and pterostigma colour, and the distinctive antehumeral stripes. Black females can be confused with females of Erythromma and the black form of Ceriagrion, but differ by details of the thorax markings. [Adapted from Dijkstra & Lewington 2006]
