Taxonomic remark Baaken, Oug & Kongsrud (2014) comment that: "A way to systematise morphological characters to define genera and delineate species into current genera was outlined by Kudenov and Blake (1978) and Blake (1981). This system has later proved to be inappropriate (Blake 2000), as more species have been described presenting more complicated characters. In [Baaken et al, 2014], small spines on the most anterior chaetigers were documented for both Pseudoscalibregma parvum and Scalibregma hanseni n. sp. The spines were clearly seen using SEM, indicating that very careful microscopy is needed to detect important characters. The presence or absence of spines was considered important for generic distinction by Blake (1981; 2000). The recent observations of small spines in several species (Mackie 1991; Imajima 2009; this study) suggest a need to reassess the importance of spines, or at least the shape and strength of the spines, for separation of genera." [details]

Spelling Bertelsen & Weston (1980) "changed for nomenclatural reasons" Scalibregmidae to Scalibregmatidae. They include a footnote on the first page referencing Scalibregmatidae in the title which comments "The Greek word bregma has as its stem bregmat-. Therefore, the family name should be Scalibregmatidae (G. Steyskal, pers. comm.)" This change has been consistently followed since by workers on the group. [details]
