Genae bearing several fine, pale, silky, backwardly-curved setae. Mouthframe smooth, very feebly sclerotized. Antenna 3-segmented; segment 3 cylindrical, almost as long as segment 2. Ocelli absent. Hypostoma smooth, testaceous and bearing a transverse row of fine pale setae. Maxilla with segment 3 of palp as long as segment 2. Prothorax with posterior half of pronotum micro-granulate and faintly longitudinally striate. Eusternum feebly defined, micro-granulate. Abdomen subtruncate posteriorly, with dorsal ampullae scarcely protuberant (not bilobed) and micro-granulate. Intersegmental skin short.

Spiracles with peritreme broadly oval, pale and not raised above general level of cuticle. Adapted from Duffy (1957).
