Abstract

Parahololepidella Pettibone, 1969 is a polynoid genus commensal with the antipatharian genus Tanacetipathes Opresko, 2001. These scale worms are elongate with numerous segments and small elytra. To date, the only other known polynoid associated with Tanacetipathes is Antipathipolyeunoa Pettibone, 1991. By re-examining the holotype of Antipathipolyeunoa, we have identified several overlooked characters that no longer distinguish this genus from Parahololepidella. Based on the presence of chaetae on the tentacular segment and elytral irregularity on posterior segments, we propose synonymizing Antipathipolyeunoa with Parahololepidella.
