Material examined. Type material. Neotype ( MNCN 16.01View Materials /16921), Pozzuoli Bay , Naples , Gulf of Naples, Italy, coll. local fisherman-A. Arias, Apr 2013. 

Non-type material. AM W.42262 (3 specimens), Bay of Machico, East coast of Madeira island, 32.72°N – 16.77°W, depth 8 m, coll. P. Wirtz.GoogleMaps 

Type locality. Mediterranean Sea , Gulf of Naples, Italy. 

Diagnosis. Prostomium anteriorly extended and pointed with two subulate frontal lips. Palps reaching chaetiger 1–3; antennae reaching chaetiger 4–10, with 8–17 ceratophoral rings, lateral projections absent; nuchal grooves semicircular to ¾ circle; peristomial cirri present. Anterior three to four pairs of parapodia with uni- to bidentate pseudocompound hooks with pointed hoods; single postchaetal lobes. Ventral parapodial lobes present ( Fig. 17View FIGURE 17 C); ventral cirri on four chaetigers. Subacicular hooks from chaetiger 16–22; pectinate chaetae with 5–10 teeth; spiralled branchiae, first on chaetiger 4–5, last single filament on chaetiger 50–70. Colour pattern of short transverse middorsal bar on anterior margin of anterior segments ( Fig. 17View FIGURE 17 A, B). Tubes consisting mainly of silt and sand with hardly any ornamentation, distal end terminating near sediment level, without tube cap ( Fig. 17View FIGURE 17 D, E).

Remarks. Rullier (1964) reported two small specimens as D. neapolitana  from Cape Verde. He stated that although he did consider them as D. cuprea  , he preferred to refer to them as D. neapolitana  as the cosmopolitan species in the sense of Fauvel & Rullier (1959). The same record was restated by Kirkegaard (1988) as D. cuprea cuprea  . Núñez et al. (1999) collected Diopatra  from two localities at Cape Verde, and reported them as D. cuprea  . We have no record of either species from Cape Verde, and in view of the recently discovered diversity of Diopatra  in this region, consider the records as indeterminable.

Three specimens of D. neapolitana  from Madeira were sent for identification to one of us (H.P.). The specimens are anterior fragments, two measure 10 and 17 mm in length for 8 and 15 chaetigers, and 5.5 and 6.5 mm in width respectively. In the third specimen (18 mm long, 20 chaetigers, 5.5 mm wide) the head and anterior six chaetigers are regenerated.

Distribution. Eastern North Atlantic, from the Bay of Biscay to the Canary Islands and the eastern Mediterranean Sea.
