( Khedhri et al. 2014): Prostomium T-shaped, with few eyespots grouped in two 'comma groups’ forming Y-shape. Eversible pharynx (proboscis) enlarged sac-like. Branchiae from chaetiger 6, basally broader and tapering to pointed end (Fig. 5 e). Paired sensorial organs from chaetiger 8 in upper zone of branchiae. Dorsal crests in dorsum, mainly in abdominal region. Parapodia with neuropodial lobes shorter than notopodial ones; notopodia carry capillaries and furcate chaetae (last ones only in abdomen region); neuropodia with capillaries and uncini (last one in posterior segments).
