Quinquelocular pores few, present on both surfaces. Cruciform pores on ventrolateral area only. Macrotubular ducts present, of 2 sizes, larger ducts with flower-shaped terminal gland. Microtubular ducts present, with small filamentous ductule. Enlarged conical setae few, with truncate or sharp-pointed apex, present on anal lobes, rarely on margin of thorax and head; hairlike setae on both surfaces.

Dorsum. With small spine-like or setose setae in rows on all segments; anal lobes well developed, each with 3 spine-like setae. Anal ring oval, with 6 or 8 setae, each as long as anal ring diameter and with few pores in a single row. Cauda present. Quinquelocular pores numerous on all segments.
