( Figs 182–189 )

Pyrellia maculipennis Macquart, 1846a: 327 ; 1846b: 199. Type localities: COLOMBIA and BRAZIL. Lectotype ♀ (from Brazil), BMNH (des. Pont 2012: 72; seen).

Musca nitida Wiedemann, 1830: 410 . Unavailable name; proposed in synonymy with Musca violacea Fabricius, 1805 (now in Calliphoridae ). Locality: BRAZIL , Bahia. 2 ♂♂, 1 ♀, NHMW (seen; Wiedemann’s 2 ♂♂ = Parapyrellia maculipennis (Macquart) ; his 1 ♀ = Morellia nigricosta ).

Pyrellia maculipennata Macquart, 1851a: 225 ; 1851b: 252. Type locality: BRAZIL, Minas Gerais. Lectotype ♀, MNHN (des. Pont 2012: 72 ; seen).

Pyrellia specialis Walker, 1861: 313 . Type locality: MEXICO. Holotype ♀, BMNH (seen).

Pyrellia centralis Loew, 1869: 37 . Type locality: CUBA. Syntypes: 1 ♂, 1 ♀, MCZ ( Pont & Werner 2006: 33; seen).

Musca violacea of authors, not Fabricius (1805: 288) [misidentifications]. This name is in any case a junior primary homonym of Musca violacea Scopoli, 1763 . Holotype ♀, ZMUC ( Michelsen 1979: 191), belongs to the Calliphoridae .
