Etymology Rathke (1843: 182, footnote) explains the derivation of Scalibregma as follows (translated): "The name is composed of (Greek for) front head and (Greek for) a tool for digging, scratching." Brown (1954) translates Greek bregma, -tos, neuter, as front part of the head, and Greek skalis -idos (feminine) as mattock or hoe. Thus Scalibregma means forehead hoe and the genus is neuter as the 2nd word bregma is neuter. [details]

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. Chaetae include capillaries, lyrate chaetae, and sometimes inconspicuous blunt, pointed, or bifurcated spinous chaetae anterior to capillaries of chaetigers 1 or 1‒2, representing homologues of lyrate chaetae; large conspicuous acicular spines absent. Pygidium with long anal cirri." (Blake, 2015: 60).Blake (2015 & 2025) examines species differences within Scalibregma, but following his diagnoses provides no indication as to the unique characters of Scalibregma compared to the other scalibregmatid genera. The presence of anterior arborescent branchiae may be the most obvious differing character state, and presence of variable anal cirri and lobes may be relevant. [details]

Grammatical gender Neuter. Rathke (1843) gave the type species a neuter species-group name, 'inflatum', consistent with his derivation etymology, and about six of the following names from later authors were given neuter adjectival species-group names. Blake & Read 2025 corrected several gender-related name endings in Blake 2025 [details]
