Status and distribution in Luxembourg
In 2012 numerous colonies of Pectinatella magnifica (Leidy, 1851) (Bryozoa, Phylactolaemata) were discovered in the reservoir of Esch-sur-Sûre (Luxembourg) fed by the river Sûre. The colonies were particularly abundant in the shallow, warm and nutrient-rich water near the riverbank, but some colonies were spotted by divers in the reservoir at a depth of 8-9 m in one site and more than 20 m in another site. There is reliable evidence that Pectinatella was present, but less conspicuous and as such not identified, in 2011 and possibly already in 2010. P. magnifica was hitherto unrecorded in Luxembourg, but known from a site near the German-Luxembourg border near Nennig (Germany, Saarland) where statoblasts were found in 2001 (Massard et al. 2013).
There is no distribution map available because no data has been entered into the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2019).
ISEIA protocol: C1 (3+2+1+1) (Ries et al. 2017: 68).
