Etymology Not stated. However, 'oligo' is few and 'bregma' is forehead. Assuming 'bregma' is included simply to link the genus to 'Scalibregma', the first described genus in the family, the authors were thus noting few of something in this genus, but it is not obvious what feature they are remarking on. Scalibregma is neuter so Oligobregma is neuter also, but contrarily the authors created or maintained feminine species-group endings for the species they newly included in the genus. [details]

Diagnosis "Body elongate and arenicoliform. Prostomium T-shaped with two prominent frontal horns; eyes present or absent; nuchal organs present. Peristomium achaetous, surrounding prostomium dorsally and forming upper and lower lips of mouth ventrally. Branchiae absent. Parapodia with well-developed dorsal and ventral cirri on posterior segments; interramal papilla present or absent. Large acicular spines present on anterior chaetigers. Capillaries present in all parapodia; lyrate chaetae present anterior to capillaries of chaetigers 2, 3, or 4; some species with short, slender, blunt or pointed spinous chaetae anterior to capillaries of chaetigers 1, 2 or 3, representing homologues of lyrate chaetae. Pygidium with anal cirri." (Blake, 2015: 79).Oligobregma and Asclerocheilus are both characterized by lacking branchiae and having acicular spines on anterior setigers. However, Oligobregma has well-developed and prominent dorsal and ventral cirri in middle and posterior parapodia while Asclerocheilus lacks parapodial cirri. [Blake, 2025] [details] Etymology Not stated. However, 'oligo' is few and 'bregma' is forehead. Assuming 'bregma' is included simply to link the genus to 'Scalibregma', the first described genus in the family, the authors were thus noting few of something in this genus, but it is not obvious what feature they are remarking on. Scalibregma is neuter so Oligobregma is neuter also, but contrarily the authors created or maintained feminine species-group endings for the species they newly included in the genus. [details] Grammatical gender Neuter. Adjectival Oligobregma species-group names should be neuter, but authors of at least eight names have not realized this and instead used feminine species-group adjectival names. [details] |
