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 papillae present; postsetal lamellae absent. Branchiae absent. Setae include capillaries, lyrate setae, and sometimes few inconspicuous spinous setae among capillaries of setigers 1‒2, blunt, pointed, or bifurcated, representing homologues of lyrate setae; large conspicuous spines absent. Pygidium with long anal cirri." (Blake, 2015: 74). [details]
Diagnosis As emended (Baaken et al 2014) "Body elongate, posterior part tapering (‘arenicoliform’). Prostomium T-shaped with distinct lateral processes. Posterior parapodia with dorsal and ventral cirri. Branchiae absent. Large acicular spines absent; small thin, pointed or bifurcate spines present in chaetiger 1." The additional character is presence of chaetiger 1 spines. [details]
Grammatical gender The genus is neuter as the last word in the compound genus name, -bregma, is neuter (see for example the derivation of type genus Scalibregma). At least four of the species-group names are appropriately with neuter suffices, including the type species Pseudoscalibregma parvum (Hansen, 1879). Ashworth (1901:296) had no comment on the genus gender, but instead clearly indicated it was neuter by using three neuter species-group names (longisetosum, parvum, reticulatum) [details]
Original description The genus was originally described in a work dated 1901, but published only in 1902. [details]
Type designation Ashworth included three species and did not indicate a type species, so the designation must be a subsequent designation. We do not yet have the information on who chose Scalibregma parvum [details]
