Diagnosis: Eyespots in two lateral groups of 15–20 eyespots each, continued dorsally as a band of smaller ones. Eleven short ventral shields from segment 2; nephridial papillae on segment 17; 25–35 pairs of notopodia; notochaetae of two types, bilimbate capillaries of equal length on segments 4–10; spinosphaera chaetae of two lengths, on segments 11–25. Neuropodia with uncini avicular in single rows on segments 5–10, in double rows from segment 11 up to end of body; thoracic uncini MF:6–7:6–7:11–12:11–12; abdominal uncini MF:4–6:5–6:7–8. Pygidium with many papillae on rosette-like with numerous projections.
