Ptychopera westbladi Notes
'Hartog (citation)- p. 391-392, "According to Ax (1951) the species occurs in Kiel Bay in quiet water on detritus-rich fine sand. The type of material collected by Westblad also from fine sand (Luther 1943). In the Deltaic area of the rivers Rhine, Meuse and Scheldt the species is also characteristic for still-water biotopes, where it has been taken from sandy mud and detritus-rich fine sand, but also from floating algae. The species has been found to be most numerous in the tidal creeks which run through the salt-marshes, and where at low tide a thin layer of water is left. In the slopes of the levees of these creeks many specimens were also found between Vaucheria patches and in the soft mud. In quiet places in the creeks, where floating algae, in particular Ulva and Enteromorpha, are driven together, P. westbladi is most abundant and associated with Promesostoma marmoratum (Schultze), P. rostratum Ax, Provortex affinis (Jensen), P. balticus (Schultze), P. tubiferus Luther and Pseudostomum quadrioculatum (Leuckart)."'......... p. 393, "The species has been found only in the months of April, May and June. In the summer months the biotope of P. westbladi was not investigated. The species was not found in October and November, when samples were taken in several salt-marsh creeks where it was present in spring."
Ax 2008 (citation)- p. 354, "Sie fehlt im Finnischen Meerbusen."
