Dear all,
I have got today a message from Neal Evenhuis:
Here are the correct numbers per family as per the Biosystematic Database of World Diptera database (numbers as of 7 July 2006)
[www.diptera.org]

>>Limoniidae - 10013
>>Tachinidae - 8322
>>Asilidae - 7093
>>Dolichopodidae - 6839
>>Syrphidae - more than 5876
>>Chironomidae - 5805
>>Cecydomyiidae - 5805
>>Ceratopogonidae - 5455

Anyway, Dolichopodidae is on the fourth place. And they are very close to the third place with thier 7011 taxonomic species according with Dolibank:
