There has been confusion regarding the delineation of terebellid genera. Some genera like Pista Malmgren, 1866 obviously are not monophyletic and opinion of necessity to revise them is widely accepted. Phylogenetic analysis of generic level morphological characters of Axionice–Pista complex shows that genera Axionice & Pista are well defined by arrangement of different lateral lobes on segments 1–3, shape of branchiae, structure of ventral pads and usually source of development of uncinal manubrium. As type species of Pista — Amphitrite cristata Muller, 1776 usually has been accepted species other than described by its author, while A. cristata s.str. has been described as Scionella lornensis Pearson, 1969 and even accepted as type species of Pistella Hartmann- Schroder, 1996.
