IdentificationBody varies from 1.7 to 2.2mm in length and is blackish brown. Thorax, tarsi, and abdominal segment 10 are a lighter blackish brown. The head is longer than wide, the prothorax bears two pairs of posteroangular setae, and is so weakly striated that it appears smooth. Antennal segments 1, 2, and 6 to 8 are dark brown, while segments 3 to 5 are yellow and the apical half of segment 5 is brown. Males and females are macropterous. Forewings are brown, with white at the wing base. Males have glandular areas on each of sternites 3 to 8. The glandular areas diminish in size from the largest on sternite 3 (Stannard, 1968).
