Melinda viridicyanea (Robineau-Desvoidy, 1830) is treated as a valid name in "Blowflies (Diptera, Calliphoridae) of Fennoscandia and Denmark" by Knut Rognes (1991).
In Systema Dipterorum however, Melinda viridicyanea (Robineau-Desvoidy, 1830) is a synonym of Melinda cognata (Meigen, 1830).
In Rognes' book Melinda cognata (Meigen, 1830) is listed as a synonym of Melinda gentilis Robineau-Desvoidy, 1830 and Melinda cognata auct. is listed as a synonym of Melinda viridicyanea (Robineau-Desvoidy, 1830).

Does anyone here know why Systema Dipterorum uses another nomenclature than Rognes (1991)?

That seems pretty obvious. If the two are (considered) synonyms, the oldest name has priority.
However, it is not straightforward to determine in this case which one is the oldest ....

Yes, it not so easy to say which name has priority when they were published the same year. But as far as I can find out, Robineau-Desvoidy's publication is considered to be older than that of Meigen from 1830.
In his book, Rognes writes a bit about nomenclature regarding these two species, and to me his conclusions seems rather solid.
Therefore, I was surprised to see that Systema Dipterorum has another nomenclature.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
