A synopsis of the Pelagic Polychaeta

First records of pelagic polychaetes in southern Chile (Boca del Guafo - Elefantes Channel)

“…12 (17 specimens), Sta. 13 (1 specimen (Dales & Peter, 1972). It has been recorded in the western South Atlantic (Orensanz & Ramírez, 1973;Fernández-Álamo & Thuesen, 1999) and the Southern Ocean (Tebble, 1962).…”

An ectoparasitic typhloscolecid polychaete on the chaetognathEukrohnia hamata from the Antarctic Peninsula

“…There is no consensus as to how many valid species occur in the genus. Dales and Peter (1972) list four species -T. muelleri Bush, 1851, T. leukarti Reibisch, 1895, Z phyllodes Reibisch, 1895 and T. grand& StopBowitz, 1948 -but note that the three latter may be junior synonyms to T. mueIleri. Fauchald (1977) recognizes six species.…”

Polychaete species (Annelida) described from the Philippine and China Seas

“…Koh & Bhaud 2001), concluding that there were many species present in different localities, and this idea became widely accepted. Although important progress has been made dealing with benthic species, pelagic polychaetes are still poorly understood; for example, the synopsis by Dales & Peter (1972) includes some 80 valid species names with 44 restricted to a single ocean basin, but 36 have been recorded from two or three oceans. Støp-Bowitz (1984) identified some problems with diagnostic features for some pelagic species, but he did not analyze their distribution patterns, which might be difficult to explain, especially in pantropical species.…”
