Genus Scalibregma Rathke, 1843 Type Species: Scalibregma inflatum Rathke, 1843. Synonym: Oligobranchus Sars, 1846. Fide Hartman 1959. Diagnosis. Body elongate, arenicoliform. Prostomium T-shaped with lateral horns. Peristomium achaetous, surrounding prostomium dorsally and forming upper and lower lips of mouth ventrally. Parapodia of posterior segments with dorsal and ventral cirri; interramal papilla present; postsetal lamellae absent. Branchiae present in anterior segments. Setae include capillaries, lyrate setae, and sometimes inconspicuous blunt, pointed, or bifurcated spinous setae anterior to capillaries of setigers 1 or 1‒2, representing homologues of lyrate setae; large conspicuous acicular spines absent. Pygidium with long anal cirri. Remarks. Until recently, Scalibregma inflatum was considered to be cosmopolitan in its distribution. Mackie (1991), however, demonstrated sufficient variability in European populations to define an additional, closely related species, S. celticum Mackie, 1991.
