Etymology Not stated. The specific epithet spinosa (masculine: spinosus) is a Latin adjective meaning 'thorny' or 'prickly', and presumably refers to the simple spines present in all parapodia of the species: ''Setae include thick, distally blunt, simple spines in all parapodia'' (Fauchald & Hancock, 1981: 20). The spelling should be neuter 'spinosum' in agreement with Mucibregma which is neuter. [details]

Taxonomy Kudenov (1985:339), examined the only specimen and suggested Mucibregma spinosa might be a member of Fauveliopsidae. Blake (2025: 214) later also examined the specimen and was satisfied it was indeed a member of Scalibregmatidae. [details]

Etymology Not stated. The specific epithet spinosa (masculine: spinosus) is a Latin adjective meaning 'thorny' or 'prickly', and presumably refers to the simple spines present in all parapodia of the species: ''Setae include thick, distally blunt, simple spines in all parapodia'' (Fauchald & Hancock, 1981: 20). The spelling should be neuter 'spinosum' in agreement with Mucibregma which is neuter. [details]
Habitat Sandy silt, at bathyal depths. [details]
Spelling The spelling of Mucibregma spinosa should instead be neuter Latin 'spinosum' in agreement with Mucibregma which is neuter. The usage by Fauchald & Hancock (1981) of feminine 'spinosa' is incorrect and should not influence subsequent taxonomists. The Code focuses solely on the gender of the genus as derived from dictionaries. [details]
