Research into the earliest proposals making the names available resulted in one new synonymy: Breviculala Ito, 1949 = Pseudacidia Munro, 1935, n. syn. (Tephritidae), the discovery of a number of earlier designations, and the recognition of available genus-group names previously thought to be nomina nuda. Discussion is made concerning type designations in the Zoological Record and type fixations by monotypy for genus-group names proposed after 1930 without a type species designation.1 aEvenhuis, Neal, L.1 aPape, Thomas1 aPont, Adrian, C.  uhttp://www.online-keys.net/sciaroidea/2000_/Evenhuis_etal_zt01912p044.pdf
