Classification [From Sendall & Salazar-Vallejo (2013:18)] "An analysis of morphology and six genes (Zrzavý et al. 2009) did not clarify the affinities for sternaspids because different approaches gave different topologies or affinities. Thus, their Bayesian combination indicates Sternaspidae are a sister group to a clade including sabellids-serpulids, sabellariids, and Trochochaeta- Spionidae-Poecilochaetus. The unweighted maximum-parsimony indicates they form a clade with sabellariids, which is a sister group to Sabellidae and Trochochaeta-Spionidae- Poecilochaetus. The weighted maximum-parsimony indicates they group with Fauveliopsidae, and together become a sister group for Sabellidae- Serpulidae, which is a sister group to Sabellariidae and the other grouped taxa of former analysis."

Nomenclature Carus (1863) placed his 'Sternaspidea' family in Class Gephyrea [details]
Taxonomy Drennan et al (2019) discuss use of the ventro-caudal shield as a generic character without molecular support. They state "sequences identified as Caulleryaspis cf. nuda [were found] to be nested within Sternaspis as an immediate sister to S. cf. williamsae. Caulleryaspis nuda has previously been noted to resemble S. williamsae, particularly in terms of overall shield outline and the presence of a thin, loosely adhered layer of sediment on the shield ..." also that "If attributes of the ventro-caudal shield are found to be unreliable diagnostic characters in future assessments, there is a possibility that many currently valid species may be composed of morphologically similar yet genetically distinct species. Conversely, multiple species may be in fact be part of a single species with considerable intraspecific morphological variability, as was found in S. sendalli." [details]
