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:MarshalliconaCerretti & Pape with type speciesMarshallicona quituCerretti & Pape,gen. et sp. nov.(Ecuador);MaurhinophoraCerretti & Pape with type speciesMaurhinophora indoceanicaCerretti & Pape,gen. et sp. nov.(Mauritius);NeotarsinaCerretti & Pape with type speciesNeotarsina caraibicaCerretti & Pape,gen. et sp. nov.(Trinidad and Tobago) andNeotarsina andinaCerretti & Pape,sp. nov.(Peru);KinabalumyiaCerretti & Pape with type speciesKinabalumyia pinaxCerretti & Pape,gen. et sp. nov.(Malaysia, Sabah). The genusAporeomyiaPape & Shima (type speciesAporeomyia antennalisPape & 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:Acompomintho caucasica(Villeneuve, 1908),stat. rev.[from nomen dubium to valid species];Acompomintho sinensis(Villeneuve, 1936),stat. rev.[from nomen dubium to valid species];Stevenia bertei(Rondani, 1865),stat. rev.[from nomen dubium to valid species];Stevenia sardoaVilleneuve, 1920,stat. rev.[from junior synonym ofRhinophora deceptoriaLoew, 1847 to valid species];Stevenia subalbida(Villeneuve, 1911),stat. rev.[from junior synonym ofRhinophora deceptoriaLoew, 1847 to valid species]. Reversal of precedence is invoked for the following case of subjective synonymy to promote stability in nomenclature:Rhinophora lepida(Meigen, 1824),nomen protectum, andMusca parcusHarris, 1780: 144,nomen oblitum. New generic and specific synonymies are proposed for the following two names:MimodexiaRohdendorf, 1935, junior synonym ofTromodesiaRondani, 1856,syn. nov.andPtilocheta tacchettiRondani, 1865, junior synonym ofStevenia obscuripennis(Loew, 1847),syn. nov.The following new combinations are proposed:Acompomintho sinensis(Villeneuve, 1936),comb. nov.[transferred fromTricogenaRobineau-Desvoidy, 1830];Tromodesia guzari(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935];Tromodesia intermedia(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935];Tromodesia lindneriana(Rohdendorf, 1961),comb. nov.[transferred fromMimodexiaRohdendorf, 1935];Tromodesia magnifica(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935];Tromodesia obscurior(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935];Tromodesia pallidissima(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935];Tromodesia setiventris(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935] andTromodesia shachrudi(Rohdendorf, 1935),comb. nov.[transferred fromMimodexiaRohdendorf, 1935].
