The world woodlouse flies (Diptera, Rhinophoridae).

The world Rhinophoridae are catalogued, recognising 33 genera and 177 species. Nomenclatural information is provided for all genus-group and species-group names, including lists of synonyms and name-bearing type data. Species distributions are recorded by country. A key to the world genera is presented. Four new genera are erected to accommodate five new species, which do not fit within any of the current generic concepts in Rhinophoridae, according to the results of a morphology-based phylogenetic analysis: Cerretti & Pape with type species Cerretti & Pape, (Ecuador); Cerretti & Pape with type species Cerretti & Pape, (Mauritius); Cerretti & Pape with type species Cerretti & Pape, (Trinidad and Tobago) and Cerretti & Pape, (Peru); Cerretti & Pape with type species Cerretti & Pape, (Malaysia, Sabah). The genus Pape & Shima (type species Pape & Shima), originally assigned to Tachinidae, is here reassigned to Rhinophoridae based on a reassessment of the homologies of the male terminalia. The following five species-group names, which were previously treated as junior synonyms or nomina dubia, are recognised as valid species names: (Villeneuve, 1908), [from nomen dubium to valid species]; (Villeneuve, 1936), [from nomen dubium to valid species]; (Rondani, 1865), [from nomen dubium to valid species]; Villeneuve, 1920, [from junior synonym of Loew, 1847 to valid species]; (Villeneuve, 1911), [from junior synonym of Loew, 1847 to valid species]. Reversal of precedence is invoked for the following case of subjective synonymy to promote stability in nomenclature: (Meigen, 1824), , and Harris, 1780: 144, . New generic and specific synonymies are proposed for the following two names: Rohdendorf, 1935, junior synonym of Rondani, 1856, and Rondani, 1865, junior synonym of (Loew, 1847), The following new combinations are proposed: (Villeneuve, 1936), [transferred from Robineau-Desvoidy, 1830]; (Rohdendorf, 1935), [transferred from Rohdendorf, 1935]; (Rohdendorf, 1935), [transferred from Rohdendorf, 1935]; (Rohdendorf, 1961), [transferred from Rohdendorf, 1935]; (Rohdendorf, 1935), [transferred from Rohdendorf, 1935]; (Rohdendorf, 1935), [transferred from Rohdendorf, 1935]; (Rohdendorf, 1935), [transferred from Rohdendorf, 1935]; (Rohdendorf, 1935), [transferred from Rohdendorf, 1935] and (Rohdendorf, 1935), [transferred from Rohdendorf, 1935].
