Diopatra micrura Pires, Paxton, Quintino and Rodrigues. 2010

Diopatra micrura Pires, Paxton, Quitino and Rodrigues, 2010: 17 –33, figs. 1–8.

Diagnosis. Presence of median papilla of upper lip unknown. Anterior dorsum without ornamentation. First four to five chaetigers with bidentate pseudocompound hooks; hoods moderately long and pointed. Subacicular hooks present from chaetigers 8–13. Pectinate chaetae with 5–10 teeth throughout body.

Remarks. Diopatra micrura lacks the double elongated postchaetal lobes in the anterior modified chaetigers present in D. biscayensis . It also lacks the dorsal papillae present in D. cryptornata and the characteristic ringshaped color patches on anterior segment characteristic of D. marocensis . The anterior edge of the prostomium is rounded, in contrast to the pointed triangular edge present in D. neapolitana . This species appears to be best characterized by not having any of the unique features characterizing the other species treated here.

Geographical distribution. Diopatra micrura is known from intertidal and shallow subtidal areas south and west of Portugal in the Atlantic Ocean.
