Antennal foramen open behind; mouthframe rather strongly sclerotized, ferruginous. One pair of ocelli present; lens round, protuberant; pigmented spot indistinct. Clypeus glabrous. Labrum strongly transverse, Hypostoma with a pair of conspicuous, paramedian, oval swellings separated by a rather broad median cleavage line. Antenna 2-segmented; segment 2 bearing a conical hyaline process. Mandible with a characteristically sculptured concavity on apical third of outer face. Maxilla with palp 2-segmented; lobe very short and stout. Labial palpi with segment 2 minute. Mentum distinct from submentum. Prothorax with pronotum sparsely setose, very finely rugose, sublateral impressions and asperities absent. Abdomen with ampullae micro-granulate, devoid of conspicuous tubercles. Tergite 9 unarmed.
