Grubeulepis kurnai sp. nov. occurs in southeastern Australia while Proeulepethus
payungu sp. nov. was collected at one site in the Indian Ocean on the continental margin of Western Australia. Pareulepis
malayana (Horst, 1913), also collected from the continental margin of Western Australia, is newly recorded from Australia,
representing a range extension of that species previously known from Madagascar, Malaysia and the South China Sea.
Four species, and four of the six known genera of Eulepethidae are now known from Australian waters. The family Eulepethidae
remains species-poor compared with most polychaete families, and now comprises 21 species world wide.

The mean density was 655 ind. m?2, presenting two peaks, the first in June 2007 with 950 ind. m?2 and the second in November 2007 with 1633 ind. m?2. The mean biomass over entire period of survey was 4.33 g dry weight (DW) m?2, with a minimum of 1.15 g DW m?2 in September 2007 and a maximum of 8.08 g DW m?2 in June 2007. The decrease of density and biomass in winter is determined by the mortality of adults, whereas the increase in numerical abundance in late spring?early summer and especially in the autumn can be explained by the recruitment of juveniles. The analysis of the size frequency histograms indicated the existence of two recruitment periods: the first in May?June and the second in September?November. From June 2007 to May 2008, the annual secondary production, mean biomass and the production/biomass ratio (P/ ) for the entire population were estimated to be 5.66 g DW m?2 year?1, 4.22 g DW m?2 and 1.34 year?1, respectively. Extracts for isozyme analysis were prepared from 23 individuals from the polluted Danube?Black Sea Canal (population C) and 25 individuals from relatively pristine area situated at only 2 km distance (population A). A genetic analysis was conducted with 29 DNA markers on 10 individuals from population A and 10 individuals from population C. The value of Nei’s genetic index was h ?=?0.1873 for population A, h ?=?0.2099 for population C and h ?=?0.2172 for the total, while the gene flow was Nm ?=?1.12. The results showed that the two sampled populations are genetically close and could be considered as a single population and genetic pool.1 aGillet, P.1 aSurugiu, V.1 aVasile, R.1 aMetais, I.1 aMouloud, M.1 aSimo, P.  uhttps://annelida.myspecies.info/node/800507nas a2200133   4500008004100000245014800041210006900189300001200258490000700270100001900277700001900296700001500315856004300330       2011                        eng d00aRedescription of the Indo-Pacific polychaete Neanthes pachychaeta (Fauvel, 1918) n. comb.

Field investigations were carried out from January to December 2007 to characterize the populations’ reproductive cycle, secondary production and dynamics. Reproduction followed the atokous type, and spawning occured from mid-June to the end of August/early September when sea temperature was highest (20–23°C). The diameter of mature oocytes was approximately 180 μm. Mean lifespan was estimated to about one year. In 2007, the mean density was 11.27 ind. m -2 with a minimum of 7.83 ind. m -2 in April and a maximum of 14.5 ind. m -2 in February. The mean annual biomass was 1.36 g m -2 (fresh weight) with a minimum of 0.86 g m -2 in December and a maximum of 2.00 g m -2 in June. The population consisted of two cohorts distinguishable from size frequency distributions. One cohort corresponded to the recruitment of 2006 and the other appeared during the study period in September 2007. The annual production of N. falsa was 1.45 g m -2 year -1 , and the production/biomass ratio was 1.07 year -1 .10aBiomedical and Life Sciences1 aDaas, Tarek1 aYounsi, Mourad1 aDaas-Maamcha, Ouided1 aGillet, Patrick1 aScaps, Patrick  uhttps://annelida.myspecies.info/node/10
