Subfamily Reinwardtiinae Brauer & Bergenstamm, 1889

This taxon is a heterogeneous, para- or polyphyletic assemblage of genera which is also reflected in its diverse costal chaetotaxy. Species from seven among the 15 currently recognized genera ( Table 1 ) were examined.

• Muscina Robineau-Desvoidy, 1830 ( Fig. 12A ), Passeromyia Rodhain & Villeneuve, 1915 , Philornis Meinert, 1890

The examined species belonging to the above genera of Reinwardtiinae share the prevalent muscid state A 4 in which vein C is bare dorsally and extensively setulose ventrally: Muscina (5 spp), Passeromyia heterochaeta Villeneuve, 1915 and P. steini Pont, 1970 , Philornis (5 spp).

• Synthesiomyia Brauer & Bergenstamm, 1893

The only included species, Synthesiomyia nudipes , has vein C only fully setulose ventrally on CS2 (state A2), although some irregular ventral costal setulae extent onto CS2 or (females only) even the basal part of CS3.

• Brachygasterina Macquart, 1851 , Palpibracus Rondani, 1863 ( Fig. 12B ), Psilochaeta Stein, 1911

The examined species of these three exclusively South American genera differ substantially from the preceding reinwardtiine genera by the dorsally extensively setulose vein C (state A8, Fig. 12B ): Brachygasterina fulvohumeralis (Malloch, 1922) , B. violaceiventris Macquart, 1851 , Palpibracus (12 spp) and Psilochaeta chalybea (Wiedemann, 1830) . Only Brachygasterina major Malloch, 1934 differs by having the dorsal setulae restricted to CS2 and CS3 (females) or CS3 (males) (state A7).
