Description
Specimens of both sexes are orange and brown and have dark brown, segmented antennae. Among wingless (apterous) specimens, females are longer than their male counterparts at respectively 3-3.1&mm and 2.7 mm body length. For winged (macropterous) specimens, this is the other way around: winged males are, at 3.4-3.5 mm, slightly larger than winged females, which measure 3.2-3.3 mm.[2]
Specimens resemble those of Perittopus asiaticus, to which it is closely related and with which it may co-occur.[2] Winged female specimens of both species are particularly difficult to reliably tell apart.[2]
