Taxonomy Neoamphitrite differs from Amphitrite in "dichotomous rather than filiform branchiae, the number of nephridia is higher, and the nephridial tubes are free rather than fused." (Reuscher et al. 2012).
Hutchings & Glasby (1988) discussed the difference between Neoamphitrite and Amphitrite: "The two genera can be differentiated, according to Hessle, by the form of the nephridia and the form of the branchiae, which in Neoamphitrite are richly branched with a distinct stalk and in Amphitrite, filiform with a very reduced stalk. We believe that these two types of branchiae are not sufficiently different to constitute a good generic character. For example, the length of the branchial stem is quite variable within and between specimens in our material, with the larger specimens often having a better developed stem. In addition some species such as Amphitrite robusta Johnson, 1901 have branchiae which are intermediate between those of Amphitrite sensu stricto and those of Neoamphitrite. The other distinguishing character used by Hessle is the form of the nephridia which he used as a generic character to separate terebellid genera. […]The majority of workers since Hessle (1917) have ignored the segmental affinities of the nephridia and most diagnoses of terebellids genera described since 1917 lack details of these structures.  [details]

Diagnosis (fide Reuscher et al, 2012) "3 pairs of dichotomous branchiae with pronounced stems in segments II–IV. Lateral lobes usually present. Nephridial papillae in segment III only or extending for a variable number of segments. Thorax with 15–39 pairs of notopodia starting in segment IV, and 14–38 uncinigerous neuropodia starting in segment V. Capillary chaetae distally hirsute. Uncini avicular, arranged in double rows in posterior thorax and, occasionally in anterior abdomen." [details]

Original description Original description by Hessle (1917: 178-179): "Drei (selten zwei?) Paar Kiemen. Die Kiemen haben einen deutlichen Stamm und sind reich verzweigt. Die vorderen Segmente sind mit Seitenlappen versehen. Die Haarborsten beginnen am vierten Segment. Die Haarborstenspitzen sind gesägt. Die Hakenborstenchsetopodien beginnen am fünften Segment. Das Basalstück der Hakenborsten ist verhältnismässig klein, der zahntragende Teil dagegen hoch. Sowohl vordere wie hintere Nephridien sind entwickelt. Die vorderen Nephridien haben bedeutend längere Schenkel als die hinteren. Sämtliche Nephridien sind frei von einander. Auch im fünften Segment sind Nephridien entwickelt.[details]

Synonymy The usage of some authors (eg Hutchings & Glasby 1988; Jirkov, 2001) is that Neoamphitrite Hessle, 1917, founded on Amphitrite affinis Malmgren, 1866 (first listed), with also N. grayi, N. groenlandica, N. ramosissima, N. figulus, and N. vigintipes, is not distinct from Amphitrite. Neoamphitrite is maintained as distinct here meantime as at least two modern reports have continued to describe new Neoamphitrite species [details]

Taxonomy Neoamphitrite differs from Amphitrite in "dichotomous rather than filiform branchiae, the number of nephridia is higher, and the nephridial tubes are free rather than fused." (Reuscher et al. 2012).
Hutchings & Glasby (1988) discussed the difference between Neoamphitrite and Amphitrite: "The two genera can be differentiated, according to Hessle, by the form of the nephridia and the form of the branchiae, which in Neoamphitrite are richly branched with a distinct stalk and in Amphitrite, filiform with a very reduced stalk. We believe that these two types of branchiae are not sufficiently different to constitute a good generic character.

The other distinguishing character used by Hessle is the form of the nephridia which he used as a generic character to separate terebellid genera. […]The majority of workers since Hessle (1917) have ignored the segmental affinities of the nephridia and most diagnoses of terebellids genera described since 1917 lack details of these structures.  [details]
