Laonome xeprovala sp. nov. [WoRMS] References: Bick, Andreas; Bastrop, Ralf; Kotta, Jonne; Meißner, Karin; Meyer, Marin; Syomin, Vitaly. (2018). Description of a new species of Sabellidae (Polychaeta, Annelida) from fresh and brackish waters in Europe, with some remarks on the branchial crown of Laonome. Zootaxa. 4483(2): 349-364. Boltachova,N.A., E.V. Lisitskaya, L.N. Frolenko, E. A. Kovalev & T. O. Barabashin (2017). The finding of polychaete Laonome calida Capa, 2007 (Annelida: Sabellidae) in the southeast Sea of Azov. Russian Journal of Biological Invasions 8: 303–306. Capa, M., van Moorsel, G. & Tempelman, D. (2014).The Australian feather-duster worm Laonome calida Capa, 2007 (Annelida: Sabellidae) introduced into European inland waters? Bioinvasions Records. 3(1): 1-11. https://doi.org/10.3391/bir.2014.3.1.01 Comments: A new Sabellid polychaete was found first time in 2009 in Dutch rivers, canals and estuaries. They where first called Laonome sp. and later Laonome calida (Capa et al. 2014), originally described from Australia. In 2012 very numerous population was recorded in the Pärnu Bay area, Gulf of Riga, northeastern Baltic Sea. According to Bick et al. (2018) all Laonome specimens studied from Europe have the same diagnostic characters and belong to one new species called Laonome xeprovala sp. nov. Also found in Sea of Azov, a new species there as well. There is one native Laonome species in the Baltic Sea. L. kroyeri has also been reported from the western part of the Baltic Sea (with salinities between 10 and 20 psu). |

Native origin (?) | Not known Comments: Name xeprovala is Greek, meaning “sudden appearance”,the invasion of this species from out of nowhere into different fresh and brackish waters in Europe" (Bick et al. 2018) |

Description of a new species of Sabellidae (Polychaeta, Annelida) from fresh and brackish waters in Europe, with some remarks on the branchial crown of Laonome. Zootaxa 4483(2): 349-364. Comments: Found on hard bottoms (Van Harinxmakanaal, Pärnu Bay), mixed sediments (Taganrog Bay), sandy silt with detritus (Hallsfjärden), clean sand (Don River) and soft clay rich in organic material and decomposing microalgae (Pärnu Bay). recorded in shallow depths from 0.5 to 12 m. In Pärnu Bay densities as high as 750 individuals m-2 were recorded, the species being the dominant species in the Pärnu rivermouth area. |
Salinity tolerance range (?) | Venice system: 2. β-Oligohaline [0.5-3psu] 3. α-Oligohaline [3-5psu] 4. β-Mesohaline [5-10psu] Comments: Fresh and brackish water species. Has been detected in fresh water (Odra and Don Rivers), and in low salinity areas (from 0.5 to about 7 psu). |
Habitat modifying ability potential (?) | Allogenic ecosystem engineers References: Bick et al. (2018) Comments: The ability of rapidly dominate a new habitat may potentially modify the sediment morphology and chemistry and disrupt the natural infaunal communities. This could result in a significant decline in native benthic species in low-salinity estuaries in the North and the Baltic Seas. |
