Pygidium with 2 pairs of lobes; median lobes large, zygotic, parallel, lobes connected via sclerotic strap, each lobe wider than long, rounded, with dentate apex; margin between lobes incised; second lobe not bi-lobed. Gland spines 17–24 ?m long, only slightly longer than median lobes, 1 gland spine on lateral margin of pygidial segment 7 (between medial and second lobes); 2 spines on margin of segment 6; 3 spines on margin of segment 5; pair of setae between median lobes. Dorsal ducts undifferentiated from marginal ducts, except for single larger marginal duct on segment 7; present in clusters (i.e. less organized than rows); 1 submedial duct present on segment 6; ca. 7 marginal-submarginal and ca. 6 submedial ducts on segment 5. Perivulvar pores: 3–4 posteromedial, 14–16 posterolateral, 18–23 posterior, 3–6 anteromedial, and 2–5 anterolateral. Trilocular pores in cluster of 6–8 near anterior spiracle; 2–3 near posterior spiracle. Microducts absent from dorsal surface of head, scattered on ventral surface of head, thorax and abdomen. Antenna with 1 fleshy seta. Cluster of gland tubercles on ventral surface of head anterior to anterior spiracle, in addition to the submarginal / marginal clusters present more posteriorly.
