Gonia cognata Rondani, 1859

ORIGINAL DESCRIPTION: 1859b: 32 (key), 38 (description).

TYPE LOCALITY: “ in agro parmensi [ Parmese territory ( Italy)]” .

TYPE MATERIAL: 1 ♀, syntype (dirty, covered with mold) ( MZUF: Box 9) : Cnephalia Rndn. / cognata Rnd. , ♀ / 472; 1 ♂, syntype (missing head) ( MSNC: Box DIPTERA Ex collezione Rondani - I) : Spalanzania [sic!] cognata Rnd. ♂ Apenn. [= Apennines] / Coll. Rondani, scatola n° 4, posiz. H-2 / Museo di Storia Naturale Università di Pisa , Calci ( PI) ex collezione Rondani .

CURRENT STATUS: junior synonym of Pseudogonia parisiaca (Robineau-Desvoidy, 1851) ( Herting & Dely-Draskovits 1993: 261) .

REMARKS: Rondani (1859b: 38) described both sexes of Gonia cognata without specifying the exact number of specimens, but giving a single measurement of length: “ Mas rarissimo lectus in agro parmensi, et hujus foemina semel inventa [The male collected very rarely and the female found once]”. We found two syntypes in this study. Rondani (1861e: 154) suggested that it could belong to Cnephalia Rondani, 1856 rather than to Gonia Meigen, 1803 . In the MZUF this nominal species is under the generic name Cnephalia and in the MSNC under the generic name Spalanzania [sic!].
