Remarks. Brauer (1858 : 465) explicitly states that he examined "one pair" of adults that were hatched from puparia collected by the Austrian entomologist Alois Friedrich Rogenhofer in horse dung. 1♂, 1♀ in NHMW each carry two labels with the information "Oesterreich / Coll. Brauer" and "inermis / det Brauer". A fragment of a puparium carries labels with "Gastrus / inermis / det Brauer" and "Coll. Brauer". We consider the pair of adults to most probably represent original syntypes, but we are deliberately abstaining from designating a lectotype at this time.
