rufofasciata Macquart, 1851 , Anthomyia

Anthomyia rufofasciata Macquart, 1851b: 239 ( 1851d: 266) , pl. 24, fig. 10. Lectotype ♂, “Isle Bourbon. M. Bigot.” ( La Réunion), by present designation, in OUMNH.

MATERIAL. — There are two syntypes, 1 ♂ and 1 ♀, in the Bigot collection in OUMNH. They stand over Bigot’s drawer label “H. [ Hydrophoria ] rufofasciata. ♀. / Anthom. id. Macq. / Île Bourbon. J. Bigot. ”. The ♂ has been labelled “ ♂ ” by Bigot. It is in very poor condition: mouldy and dirty; both hind legs and most of abdomen missing; right wing glued back on neck. The ♀ is labelled by Macquart “ Anthomyia / rufofasciata / ♂ ♀. Macq. n. sp.”, and is also in poor condition. I have labelled and designate herewith the ♂ as lectotype and the ♀ as paralectotype. Stein (1907b: 286) also studied one of these specimens and could only comment that “das Stück ist ganz zerfressen” .

With these syntypes there is a single unlabelled ♀ of Stomoxys niger Macquart, 1851 , evidently misplaced and not a syntype.

In OUMNH, there is a damaged ♀ labelled by Macquart as “ Anthomyia / rufofasciata / n. sp.”. It has no data, but it is labelled “ex coll. Bigot”. It may well be a misplaced syntype, since Macquart described no other species as rufofasciata in the Muscoidea, and so I have labelled it as paralectotype.

CURRENT IDENTITY. — Both syntypes belong to Gymnodia Robineau-Desvoidy, 1863 , and could be identical with either G. tonitrui (Wiedemann, 1824) or G. gentilis (Robineau-Desvoidy, 1830) , both of which are known to occur on La Réunion. Because of their poor condition, the identity of the types is difficult to determine, the more so since the venational characters given by Emden (1951: 470) are not entirely unambiguous. The ♂ lectotype has a yellow abdominal syntergite 1 + 2, and the ♀ a more broadly grey-tipped scutellum; both have a more upcurved vein M. Both appear to be Gymnodia tonitrui ( Pont 1980: 734) . The second OUMNH ♀ is Fannia canicularis (Linnaeus, 1761) .
