Reinwardtiinae Brauer & Bergenstamm 1889

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).
