Iridictyon trebbaui is a species of broad-winged damselfly in the family Calopterygidae.

[1][2][3][4] It is found only on the tepuis of Venezuela and Guyana at elevations of 300–1,300 m (980–4,270 ft) above sea level.

[1][5] Iridictyon trebbaui has a restricted range and is only known from a few locations.

However, its range is protected by a number of protected areas (e.g., Canaima National Park) and there are no threats to its habitat.
