Length: 3.5–4.8 mm.

Colour: Light pale brown.

Body: Small, abdomen usually appears shorter than thorax and tapered posteriorly.

Head: Not as wide as pronotum. Tear-shaped robust setae present on top of head. Antennae as long as body, first third robust and then tapers to thin elongate segments.

Thorax: Broad. Pronotum wider than head, with all four corners produced into points. Outer margin of pronotum and much of the dorsal surface covered with dense tear-shaped robust setae. Hind margins of meso- and meta-nota convex. Inner margin of wing pads with tear-shaped robust setae present; outer margin of wingpads without robust setae. Anterolateral margin of mesonotum with tear-shaped robust setae present. meso- and metanota without obvious bosses at base of wingpad but with patch of tear-shaped robust setae; surface of nota also with tear-shaped robust setae present.

Legs: Hind legs relatively long compared to the body. Outer surface of femora smooth, outer margin of femora with short robust setae present. Outer surface of tibiae triangular in appearance with strong central ridge; all edges with short robust setae.

Abdomen: Dorsal cuticle reticulate, especially from tergites 5 to 10. Hind margins of tergites with tear-shaped robust setae present, also scattered on surface of tergites. Hind margin of tergite X circular, enclosing paraprocts, gill stalk and cercal base. Sternites with long setae present. Paraprocts triangular, tapering posteriorly; surface reticulate; length greater than width at base of paraproct.
