Included in the Empria longicornis group along with the species alector, alpina, longicornis, and minuta, all of which are similar. The posterior margins of the pronotum are pale, as are the tegulae and the basal third of the hind tibia to some degree. Paired pale patches on tergites 2 to 6. The ratio of the antennal flagellae to the breadth of the head, along with genitalia characteristics are needed to confirm the identification of this group. See Prous, et al 2011.
