Parapionosyllis labronica Cognetti, 1965

Parapionosyllis labronica Cognetti 1965: 68 , Fig. 2 ; San Martín 1984a: 191 ‒194, Pl. 41; San Martín 2003: 278 ‒281, Figs 151‒ 152.

Material examined. St. 10: 1 individual.

Distribution. Mediterranean Sea, Eastern Atlantic Ocean ( San Martín 2003).

Remarks. The single, complete, well-preserved individual clearly corresponds to the original description ( Cognetti 1965). It is noteworthy that this individual does not show parapodial glands, as in the original description ( Cognetti 1965) and in other topotypic individuals from the Tyrrhenian Sea (pers. obs.). However, San Martín (2003) described P. labronica as a species with simple parapodial glands. This inconsistency between different descriptions may suggest that P. labronica actually represents a species complex.

Up to now this species appeared as typically related to shallow environments ( Cognetti 1965; San Martín 2003), this is the first record in deep environments.
