vittatum Macquart, 1851 , Microchylum

Microchylum vittatum Macquart, 1851b: 230 ( 1851d: 257) , pl. 23, figs 11, 11a. Lectotype ♂, “ Brésil. Bahia. Muséum.” ( Brazil, Bahia), by designation of Albuquerque (1950c: 2), in MNHN.

MATERIAL. — There are 1 ♂ and 3 ♀♀ syntypes under no. 1866 of the Macquart collection in MNHN. Albuquerque (1950c: 2) designated the ♂ as lectotype and the 3 ♀♀ as paralectotypes. As noted by Albuquerque, the lectotype is in poor condition: head mostly eaten away and abdomen squashed ; left hind tarsomeres 4-5, right foreleg and both mid legs missing; left wing detached and glued to a small old tag “35”. It has the accession no. 4.44 ( Brazil, Bahia, collector Verreaux) .

The three paralectotypes are in much better condition. All have the accession no. 4.44, and each has a small tag with the numbers “37”, “38” and “40” respectively.The ♀ with no. 40 also has Macquart’s label “ Microchylum / vittatum. ♂ ♀ / Macq. n. g., n. sp.”.

CURRENT IDENTITY. — Albuquerque (1950c: 2, 3, figs 7-10) redescribed the species and placed it in the genus Limnophora Robineau-Desvoidy, 1830 , an assignment with which I agree ( Pont 1972: 29; Carvalho et al. 1993: 99; 2005: 158). It is a species with vein R 1 bare, four postsutural dorsocentrals, sternite 1 bare, arista short-plumose, and mid tibia with one posterior seta placed well in basal half of tibia. Lopes & Couri (1987: 654, figs 28-32) have redescribed the ♂ and illustrated the terminalia.
