Body 5.9-8.1 mm long, white, nearly cylindrical, tapering anteriorly, and bluntly rounded posteriorly. Amphipneustic. Mouth hooks fairly heavy and smooth along their lower margins. Anteroventral part of each abdominal segment with hooklets or spinnles. Anterior spiracle fan-shaped terminating in eight (sometimes nine) small papillae, each bearing several minute pores on its truncate extremity. A conical depression faintly visible behind these papillae. Posterior spiracles terminal, chitinized plates borne on paired protuberances above the horizontal axis, and separated by a distance equal to approximately half the length of a single plate. Each plate is a vertically elongate sclerite bearing four slightly curved spiracular slits. These slits nearly enclose the spiracular scar, which is near the centre of the plate. Four tufts of branched, radiating hairs arise from clearer areas near the spiracular slits.
