Length: 5 mm.

Colour: Variable, darker head and tergite X, nota with darker base colour and pale patches, first few abdominal segments lighter in colour than the more posterior segments.

Body: Robust.

Head: Antennae as long as body, segments robust until tip and darkening near tip; long fine setae on first 10– 20 segments. Darking mottling pattern in posterior area. Single long fine setae medial to base of antennae.

Thorax: Pronotum broader than length. Notal surface with short robust socketed setae, margins without a fringe. Pronotum and mesonotum with single long fine setae in posterior (and anterior for pronotum) area either side of medial suture.

Legs: Hair fringe of long fine setae on tibiae and femora. Distal margin of femora with robust setae, socketed (if setae not visible sockets will be). Outer surface of femora predominantly brown with pale central patch and another pale patch in distal area. Tibiae with dark stripe and a dark band in proximal area.

Abdomen: Tergites with some scattered short robust setae on surface. Hind margins with short paddle-like setae some with a curve at the tip. Hind margin of tergite X with broad robust setae. Tergite X with central pale patch in the posterior area and off-centred two pale spots. Gills dark brownish/purplish. Cerci short approximately 20 segments and robust in appearance; darkening near tip; segment 6–10 with very long setae on margin exceeding segment length.
