Redescriptions of two Porricondyline gall midges originally described by De Meijere (Diptera, Cecidomyiidae)

The confusion of nomenclature and classification in the European Porricondylinae was largely cleared up by the excellent revisionary work of Panelius (1965). There are, however, still many unidentified species listed in his revision owing to the destruction of types and the inadequacy of many original descriptions. Recently, we have had an opportunity to examine De Meijere’s type specimens kept in the Zoölogisch Museum, University of Amsterdam. Because the specimens were not kept in good condition for examination, we dissected some parts of the specimens and remounted them by using Berlese medium. The following are redescriptions of two porricondyline gall midges described by De Meijere (1901, 1906). In particular, detailed examination of the male genitalia has furnished us with much information about their generic position.
