Diopatra budaevae sp. nov. Figures 2 A,B, 3; Table 1 Material examined. Type material. Holotype: (MNCN 16.01 /17809), La Laja beach, Gran Canaria, Canary Islands, 28°03’N – 15°25’W, intertidal, coll. A. Arias, 12 Aug 2012. Type locality. Eastern North Atlantic, Canary Islands, Gran Canaria, La Laja beach, 28°03’N – 15°25’W, intertidal. Diagnosis. Prostomium anteriorly rounded with two subovate frontal lips; antennae to chaetiger 9–11; with six to seven ceratophoral rings, lateral projections absent; nuchal grooves crescentic; peristomial cirri absent. Anterior four pairs of parapodia with bidentate pseudocompound hooks with falcate hoods; single postchaetal lobes. Ventral parapodial lobes absent, ventral cirri on four chaetigers. Subacicular hooks from chaetiger 10; pectinate chaetae with 9–15 teeth; spiralled branchiae, first on chaetiger 4, last on chaetiger 16. Description. Incomplete holotype 7 mm long for 38 chaetigers, 0.7 mm wide. Ethanol stored specimen overall whitish with dorsal colour pattern consisting of brown prostomium, lateral brown spots and intersegmental lines on anterior chaetigers (Figs 2 A, 3A). Prostomium anteriorly rounded with two subovate frontal lips separated by a small gap (Fig. 3 A). Ventral upper lips oval with papilla-like median section between lips; lower lip without median section. Palps reaching to chaetiger 2, lateral antennae to chaetiger 11, median antenna to chaetiger 9; ceratophores with five to six proximal and a long distal ring, equal to about three proximal rings. Ceratostyles with irregularly distributed slightly raised circular sensory buds, styles tapering to distal ends. Nuchal grooves crescentic. Peristomium slightly shorter than chaetiger 1; peristomial cirri absent (Fig. 3 A). First four pairs of parapodia modified, slightly prolonged and directed anteroventrally with rounded prechaetal lobe and subdigitate postchaetal lobe (Fig. 3 B, C). Thereafter prechaetal lobe becoming reduced, absent from about chaetiger 8–9. Postchaetal lobe becoming smaller but ...
