There are no lobes on the fourth segment. The 15-17 ventral shields are somewhat fused with the tori. Two pairs of branchiae, which may be either bushy or divided on a single plane, they are often borne on long stalks, the first pair being larger. Nephridial papillae inconspicuous. Pygidium with terminal anus surrounded by short papillae. Dorsal setae capillary, broadly winged at the end, with a short smooth tip.
