Dipterologiae Italicae prodromus

A prodromus is a preliminary publication intended as a basis for future work – Rondani's expression is "un programma, o, per meglio dire, una proposta che vuol essere esaminata e discussa e quindi riformata, dietro le considerazioni dei dotti in tale materia", in English a programme, or, better to say, a proposal to be examined and discussed and therefore changed, after the considerations of scholars in such materia.

Volume I is an overview presented as a dichotomous key of classification of the thirty-two families and eighty-four stirpi (subfamilies) of European Diptera.

The problem of nomina nuda was resolved as the succeeding volumes were published and the errors, misspelling of names and misprints identified by Loew were largely corrected in later errata and the Prodromus as a whole is one of the most cited works on European Diptera.

They are titled Species italica ordinis dipterorum in genera characteribus definita, ordination collectae methodo analitica distinctae, ex novis vel minus cognotis descriptis.
