Recent studies have shown that phylogenetic relationships based solely on paragnaths give different topologies and clade support than relationships inferred from other character systems. Furthermore, recent revisions and species descriptions continue to increase the range of known paragnath forms. We provide the first comprehensive overview of these important morphological characters, with the aim of encouraging more consistent observation and use of a standardized terminology in future studies. Illustrated descriptions and definitions of all known paragnath types are presented and compared. New terminology is introduced to improve description of paragnath types. Hypotheses are proposed for the chemical composition of pargnaths (scleroprotein), homology between different paragnaths types, and earlier studies implicitly proposing the homology of scleroprotein paragnaths with the more plesiomorphic pharyngeal soft papillae are addressed.1 aBakken, T.1 aGlasby, C., J.1 aWilson, R., S.  uhttps://annelida.myspecies.info/node/1301667nas a2200121   4500008004100000245011600041210006900157300001000226490000900236520124100245100001501486856004401501       2006                        eng d00aRedescription of two species of Neanthes (Polychaeta: Nereididae) possessing a large notopodial prechaetal lobe0 aRedescription of two species of Neanthes Polychaeta Nereididae p  a27-330 v70S33 aPhylogenetic analyses of “nereidids with paragnaths” indicated that species currently assigned to Neanthes sensu lato possessing a notopodial prechaetal lobe as large as the notopodial dorsal and ventral ligules were grouped in a separate clade with uncertain relationships to nominal Neanthes taxa. Further studies of these species are required to test this theory. Literature studies and examination of material alike prove that redescriptions of several species are needed until phylogenetic analyses can be undertaken. To meet this goal material from two species is included here for redescription, being necessary to reveal as many details as possible for a forthcoming phylogenetic analysis. Neanthes bongcoi Pillai, 1965 was originally described from the Philippines and is redescribed based on a quantity of specimens. It is here reported to be common in northern Australian waters. Neanthes meggitti Monro, 1931 is redescribed based on type material and a lectotype is designated for N. meggitti. Both N. bongcoi and N. meggitti are characterised by presence of a notopodial lobe as large as dorsal and ventral notopodial ligules in anterior chaetigers. Relevance to similar characteristics in related species is discussed.1 aBakken, T.  uhttps://annelida.myspecies.info/node/1801263nas a2200145   4500008004100000245006800041210006500109300001200174490000700186520083600193653001001029100001501039700001901054856004401073       2005                        eng d00aPhylogeny of nereidids (Polychaeta, Nereididae) with paragnaths0 aPhylogeny of nereidids Polychaeta Nereididae with paragnaths  a507-5470 v343 aA phylogenetic analysis was conducted of the Nereidinae — those members of the Nereididae (Polychaeta) with pharyngeal paragnaths. We had two objectives: to test the monophyly of currently accepted genera, subgenera and informal subgeneric groupings within the Nereidinae, and, if warranted, to propose a more natural classi.cation of the Nereidinae. Parsimony analyses were undertaken, including 52 terminal taxa from all genera and informal groupings from the large heterogeneous genera Nereis , Ceratonereis , Neanthes and Perinereis . Analyses of a character set of 52 informative characters yielded more than 10 000 equally parsimonious trees with a length of 176 steps (consistency index [CI] = 0.34, retention index [RI] = 0.66). Reweighting three times resulted in 445 most parsimonious trees with length 54.62 (CI = 0.5910aRW_CV1 aBakken, T.1 aWilson, R., S.  uhttps://annelida.myspecies.info/node/20
