Notopodia beginning on segment 4, extending for variable number of segments, frequently to posterior body; notochaetae medially winged and distally serrated, and alimbate and serrated, frequently with blade at an angle, usually with transition on types of chaetae from anterior to midbody notopodia. Neuropodia beginning on segment 5, with short handled avicular uncini in completely intercalated to partially back-to-back double rows from segment 11 until posterior body (Fig. 2A, B) (Hutchings et al. 2021).
