Diagnosis "Sternaspids with introvert hooks tapered. Pre-shield region with 7 segments. Ventro-caudal shield flexible with abundant sediment particles firmly adhered." [details]
Etymology Honors Dr Maurice Caullery, in recognition of his studies on polychaete reproductive biology and taxonomy, and especially because of his monograph on the Siboga Expedition, which took him 40 yr, and contained many new species. Caulleryaspis is a free combination of his last name and the second part of Sternaspis (Gr. shield) to stress the affinity with the stem genus. Gender: feminine. [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]
