As it is very known, Mr. Dyanega, the large " taxonomic specialist " lepidopterologist of the world, is also a large impostor. Because, the name " Oestroides " belongs to Burmeister (1829) from where derive the word " Oestroidea " of Gravenhorst (1843) only for the Oestridae family.  But Rohdendorf (1964) established the name " Oestridea " for the superfamily.  
As for the name " Sarcophagoidea ", it belongs to Shannon (1926) for the family.  Also Rohdendorf (1964) gave the name " Sarcophagidea " for the superfamily.  Thus, the priority is in Rohdendorf.  See Sabrosky (1999) to eliminate your stupidities.
