Hi Geurt,

Thank you for the reply, I really appreciate it.

Diatomeen im Süßwasser-Benthos von Mitteleuropa" (G. Hofmann, 2011) appears to me very practical for routine taxonomy for the obvious reasons you mentioned above and i have already ordered it.

Süßwasserflora von Mitteleuropa 1-4 is clearly insufficient after the rapid changes in diatom taxonomy. So, In attempt to enrich my library with some other books, aside from keeping track of new publications (papers etc), I wanted to shortlist the most useful guides. Thank you again for the suggestions.

Best regards and I wish you many many diatom surprises !!!

Hi Ioulianos,

The French book you mention is great. Here is one I like too, it is for the main diatoms found in Southern Australia but many of them are cosmopolitian temperate species: 

Gell, P.A., Sonneman, J.A., Reid, M.A., Illman, M.A., Sincock, A.J. (1999) An Illustrated Key to Common Diatom Genera from southern Australia, Cooperative Research Centre for Freshwater Ecology, Identification Guide No 26

already done, although in french they are pretty practical and useful

Thank you Carlos

You can download those, though these are seems shorter in size in respect Crammer and Lange Bertalot series..
