ovativentris Macquart 1851 , Anthomyia

Anthomyia ovativentris Macquart, 1851b: 240 ( 1851d: 267) , pl. 24, fig. 12. Lectotype ♂, “Amérique méridionale. Montévidéo. M. d’Orbigny. Muséum.” ( Uruguay, Montevideo), by designation of Albuquerque (1950c: 6), in MNHN.

MATERIAL. — There is 1 ♂ syntype in MNHN, under no. 1883 of the Macquart collection. It has the accession no. 9522.34 and an old hand-written tag “26”. These figures refer to a collection made by d’Orbigny in South America. In d’Orbigny’s catalogue, the number 9522.34 refers to material collected around Montevideo, 30 September to 15 October 1826, and no. 26 was “sur les plantes”. It is labelled by Macquart “ Anthomyia / ovativentris / ♂. Macq. n. sp.”. It is not well preserved ; it is rather mouldy; left antenna, left foreleg and right mid leg missing. It has been designated lectotype by Albuquerque (loc. cit.) .

CURRENT IDENTITY. — The lectotype was redescribed by Albuquerque (1950c: 5, 6, figs 16-18), who assigned it to the genus Gymnodia Robineau-Desvoidy, 1863 , an assignment which I later followed ( Pont 1972: 24). However, Albuquerque described the basal node of veins R 2 + 3 and R 4 + 5 as “com cilios ventrais e dorsais”, and so A. ovativentris clearly belongs to Limnophora Robineau-Desvoidy, 1830 , as had already been pointed out by Séguy (1937: 461; 1938: 113). I can confirm this generic assigment from study of the lectotype (see Carvalho et al. 1993: 97; 2005: 155): prosternal area

totally obscured, vein R 4 + 5 setulose at base, vein R 1 bare, four postsutural dorsocentral setae, arista pubescent, sternite 1 bare, and mid tibia with one posterior seta (without trace of a second scar).
