Ancistrosyllis McIntosh, 1878


Genus Ancistrosyllis McIntosh, 1878 

? * Ancistrosyllis cingulata  ( Korschelt, 1893)


LITERATURE RECORDS: Korschelt 1893; Aleffi et al. 1988; Castelli 1991; Požar-Domac 1994.

REMARKS: Korschelt (1893) described the species Harpochaeta cingulata  from the larval planktonic stage found in the bay of Trieste, placing it in the family Syllidae  . Ehlers (1908) considered the genus Harpochaeta  as being synonymous with Ancistrosyllis  and Fauvel (1923 a) provided a description of the species as A. cingulata  , based on Korschelt's (1893) description and drawings. However, until a formal redescription is done, this species should be considered as a Pilargidae  incertae sedis as it may belong to the genus Cabira  . Although Korschelt (1893) clearly pictures a median antenna, which suggests an Ancistrosyllis  (but not all Ancistrosyllis  have a median antenna), the distinguishing features that separate Ancistrosyllis  from Cabira  (such as the degree of dorso-ventral body compression, a peristomium sharply divided from segment 1 in Cabira  but not in Ancistrosyllis  , and possibly the pharynx shape, being highly muscular and sometimes long and looped in Ancistrosyllis  ), may not have been fully developed in a planktonic juvenile. Besides Korschelt (1893) also illustrates four lobes in the hind brain, which raises further difficulties in identifying the genus, as the Cabira  reportedly has 3 and Ancistrosyllis  5 lobes (C. Glasby, pers. comm.).
