Genus Myxicola Koch in Renier, 1847

Type species

Myxicola infundibulum ( Montagu, 1808) , as Amphitrite infundibulum Montagu, 1808 .

The following diagnosis is in accordance with Fitzhugh (1989, 2003) and Capa et al. (2011).

Diagnosis

Large to small-sized sabellids from a variety of substrata (soft and hard bottoms, of both natural and anthropic origin). Radioles connected by a high palmate membrane. Dorsal lips barely visible, located on the inner margin of ventral lips, extending between dorsal and ventral-most radioles, with (generally) well-developed dorsal radiolar appendages, supported by an acellular axis. Ventral radiolar appendages, pinnular appendages and ventral sacs all absent. Peristomium with ventral triangular lobe. Parapodia inconspicuous; 3 to 8 thoracic chaetigers with narrowly hooded notochaetae organised in tufts and neurochaetae as acicular uncini forming discrete or inconspicuous tori,arranged in one row and characterised by a main fang surmounted by a variable number of teeth; companion chaetae absent. Abdominal chaetigers with narrowly hooded neurochaetae and numerous notochaetae as small and modified avicular uncini, and showing a distinct main fang surmounted by a variable number of smaller teeth;handle absent or vestigial; abdominal uncini arranged as a single row forming an uninterrupted belt around each abdominal chaetiger.Radiolar eyes present (both as simple eyespots and compound eyes,coupled or in single units) or absent; peristomial eyes absent or present; lateral eyespots present or absent; pygidial eyes generally present.
