The Muscini flies of the world (Diptera, Muscidae): identification key and generic diagnoses Author Nihei, Silvio Shigueo Author Carvalho, Claudio José Barros De text Zootaxa 2009 1976 1 24 journal article 10.5281/zenodo.185153 0b5ad8cc-9b48-4700-acc5-012d1707f720 1175-5326 185153 Curranosia Paterson, 1957 Curranosia Paterson, 1957 : 445 . Type species: Orthellia pilarara Snyder, 1951 [= Lucilia spekei Jaennicke, 1867 ]. Diagnosis. Colouration shining metallic blue or green; wing without maculae. Female with proclinate frontoorbital seta undeveloped; interfrontal seta absent. Dorsocentrals 2+3-4. Posthumeral present; intrapostalar present. Prosternum setulose or not. Greater ampulla bare. Katepisternals 1+2 or 1+3. Katepimeron setulose. Posterior portion of suprasquamal ridge setulose. Wing with the apical portion of stem-vein setulose dorsally and usually setulose ventrally; R4+5 setulose dorsally and ventrally; Rs node setulose dorsally and ventrally; M bent forward towards R4+5. Lower calypter enlarged posteriorly, extending under base of scutellum. Subcostal sclerite setulose ventrally. Mid tibia with a strong submedian seta on ventral to posteroventral surface. Calcar strong. First abdominal sternite setulose only on lateral margins. Comments. Cladistic analysis of Muscini (Nihei & de Carvalho 2007a ) corroborated the division of the genus into two species-groups: gemma and spekei . However the genus was not supported as monophyletic, with the gemma -group placed outside and, therefore, treated therein as a genus-ranked taxon. The main differences between both groups concern the presence/absence of a marginal spined process on male cercal plate and presence/absence of anteroventral setulae on wing subcostal sclerite (Nihei & de Carvalho 2007a ). A distinction of a species-group in Curranosia was earlier considered by Zielke (1973 , 1974 ) with his pilarara - group (now known as spekei -group), contrasting with an unnamed group which included C. gemma (Bigot) and C. prima (Curran) (this group named as gemma -group by Nihei & de Carvalho 2007a ). Distribution (7 species). Afrotropical. References. Peris (1967) , Zielke (1971) .
