Type species

Diagnosis

Based on Carrerette & Nogueira (2015), Nogueira et al. (2015) and Wang et al. (2020). Eyespots, if present, at basal part of prostomium; lobes on segments 1 and 3 or 1 and 2/3 (in combination of segment 2 and 3), sometimes also on segment 4. Three pairs of branching branchiae, on segments 2–4. Rectangular or trapezoidal mid-ventral shields from segments 2–3 to posterior region where notopodia terminate; last segments of the glandular region usually subdivided by transverse bands. Conical to rectangular notopodia beginning on segment 4, extending for 17 segments, until segment 20; notochaetae all narrowly winged. Neuropodia beginning from segment 5, bearing pectinate uncini, arranged in single rows on segments 5–10 and in double rows on segments 11–20. Genital papillae on segments 6–8. Pygidium smooth to papillate.
