Dear Olivier,

There are full descriptions of each in Gofas, et al. 

If I understand correctly, the differences include the protoconch (D. concatenata's has more than two whorls, the first globose and smooth, the second with spiral sculpture; D. coppolae's has two whorls, the first smooth, the second with axial ribs) and type of beading (D. concatenata's beads become axially-elongated, whereas D. coppolae's are pearl-like).

I hope this is helpful.
