Fauna Europaea (perhaps no more reliable than Nomina Insecta Nearctica?) gives
sororcula (Loew 1869) (- originally in
Leia) as a synonym of
Rondaniella dimidiata (Meigen 1804).
Leia abbreviata,
apicalis,
elegans,
terminalis and
variegata are all listed as synonyms as well. As Peter Chandler is listed as the taxonomic specialist for this page, I'm inclined to accept what it says, so
Rondaniella dimidiata looks like the current name.
