Updated key to genera of Polynoinae sensu lato present in the Northeast Atlantic incl. the Mediterranean Sea Based on Barnich & Fiege (2003, 2009, 2010), Barnich (2011), Barnich et al . (2017), Chambers & Muir (1997), Charles et al. (2014), Fiege & Barnich (2009), Hartmann-Schröder (1996), Jourde et. al (2015), Núñez et al . (2015), Pettibone (1963), Ravara & Cunha (2016), Taboada et al. (2019) and this study. In order to allow for identification of anterior fragments, the current key avoids, where possible, the use of numbers of elytra and segments as main distinguishing character. 1. Dorsal tubercles T-shaped. (Cephalic peaks absent. Lateral antennae terminoventral. More than 15 pairs of elytra. More than 50 segments). Acholoe Claparède, 1870 – Dorsal tubercles nodular. 2 2. First three pairs of elytra modified, with translucent central area. (Cephalic peaks absent or present. Lateral antennae ventral. 15 pairs of elytra. Fewer than 50 segments). Gorgoniapolynoe Pettibone, 1991 – First three pairs of elytra not modified. 3 3. Dorsum with one or more median nodules per segment, starting from segment 2. (Cephalic peaks absent. Lateral antennae ventral. 18 pairs of elytra. Fewer than 50 segments). Bathynoe Ditlevsen, 1917 – Dorsum without median nodules in anterior segments (may start later). 4 4. Prostomium with cephalic peaks (can be small or masked when prostomium in bad condition). 5 – Prostomium without cephalic peaks. 18 5. Notochaetae with two kinds of tips. Lateral antennae ventral or terminoventral. 6 – Notochaetae all with similar, stout tip. Lateral antennae ventral. 9 6. Some notochaetae with slender furcate tip, most others with stout, entire tip. Cephalic peaks small. Lateral antennae terminoventral (15 pairs of elytra. Fewer than 50 segments). Pettibonesia Nemésio, 2006 – Notochaetae different. Cephalic peaks obvious. Lateral antennae ventral. 7 7. Long notochaetae with stout, blunt tip, short notochaetae abruptly tapering to sharp, pointed tip (15 pairs of elytra. Fewer than 50 ...
