Re: Striatella unipunctata

Following Beatsy's query on resolution, I looked for some SEM images of Striatella unipunctata in order to see what there was was to be seen ;) Page 92 Fig. 5-d (see link below) would seem to indicate that the beading is perhaps more of an artifact than not. https://www.researchgate.net/publication/...
