Notes 
From editor or global species database
Checked: verified by a taxonomic editorDiagnosis "Prostomium without cornua, rounded anteriorly and prolonged caudad; without nuchal cirrus. In genotype one pair of eyes. Branchiae in genotype two pairs, on third and fourth somites, wholly free from the parapodial lamellae. Parapodia all free from each other, none of the neuropodia being connected by a membrane; no interparapodial pouches. Anterior parapodia bearing only capillary setae. Hooded crochets appearing in neuropodia caudad but notopodia remaining with only capillary setae. Crochets with beak bifid and lacking apical tooth." (Chamberlin, 1920: 18) [details]

Checked: verified by a taxonomic editorEtymology The name of the genus is composed by the prefix of Greek origin ana-, meaning 'up', 'back', 'against' or 'not, without', and the name of the genus Spio Fabricius 1785, the type of the family Spionidae, and apparently refers to the distinctive characters of the new genus which would differenciate it from the rest of the members of the family: "Close to Spionides but wholly lacking the characteristic lateral pouchs of the latter and the nuchal cirrus. The crochets seem to be of distinctive form" (Chamberlin, 1920: 18).  [details]

Checked: verified by a taxonomic editorSynonymy Maciolek (1981: 229) revised the holotype of the type species, Anaspio boreus Chamberlin, 1920, and found it to be a damaged specimen of Prionospio sp. which had lost the first pair of branchiae, as well as all the branchiae after the third pair. The genus is thus a junior synonym of Prionospio Malmgren, 1867.  [details]
