The specialized mouthparts of this group of hematophagous muscids leave no doubt as to their monophyly. Among the 10 currently recognized genera I have examined species belonging to five of them ( Table 1). • HaematobiaLe Peletier & Servillein Latreille et al., 1828 The examined species Haematobia exiguaMeijerein Schat, 1903, H. irritans(Linnaeus, 1758)and H. minuta(Bezzi, 1892), have vein C extensively setulose ventrally (state A4), but one examined species or subspecies ( Haematobia thirouxi titillans(Bezzi, 1907))has the ventral costal setulae confined to CS1 (state A2). • HaematoboscaBezzi, 1907 Among the five examined species, Haematobosca alcis(Snow, 1891)and H. sanguisugens(Austen, 1909), stat. rev., have vein C extensively setulose ventrally (state A4), H. sanguinolenta(Austen, 1909)and H. stimulans(Meigen, 1824)have the ventral costal setulae confined to CS1 (state A2), and Haematobosca atripalpis(Bezzi, 1895)has the ventral setulae confined to the basal half of CS1 (state A1). • NeivamyiaPinto & Fonseca, 1930 The only examined species, Neivamyia flavicornis(Malloch, 1928), has the ventral costal setulae confined to CS1 (state A2). • StomoxysGeoffroy, 1762 In most examined species ( Stomoxys calcitrans(Linnaeus, 1758), S. inornatusGrünberg, 1906, S. nigerMacquart, 1851, S. pallidusRoubaud, 1911, S. sitiensRondani, 1873and S. taeniatusBigot, 1888) vein C is extensively setulose ventrally (state A4), but in one species ( Stomoxys indicusPicard, 1908) the ventral costal setulae are confined to CS1 (state A2). • StygeromyiaAusten, 1907 In the only examined species, Stygeromyia sanguinariaAusten, 1909, vein C is bare ventrally except for single setulae at the extreme base of CS1 (state A0).
