Diagnosis. Polycirridae with an expanded, often trilobed, upper lip bearing tentacles of two or three kinds. Outer lower lip enlarged and resembling a ventral pad. Notopodia from segment 3 continuing for 10 – 70 segments; neuropodia from segment 7 – 18, continuing to pygidium. Notochaetae capillaries of various types including smooth, hirsute, and pinnate (= spinose or corn-eared), present in anterior body only. Neurochaetae avicular uncini, present in anterior and / or posterior body. Five or more pairs of nephridia (segmental organs) in anterior segments opening through pre-gular nephridial papillae (segments 3 and 4) and post-gular nephridial papillae (segment 5 onward).
discussion
Remarks. The diagnosis is modified from Holthe (1986 b) and Hutchings & Glasby (1986). The genus was shown not to be monophyletic in Nogueira et al. (2013).
