Subfamily Cyrtoneurininae Snyder, 1954

This is essentially a Neotropical group extending into southern North America. It is rather heterogeneous and doubtfully monophyletic. Among the currently included 12 genera I have examined species from five of them ( Table 1 ). They all agree in having vein C extensively setulose ventrally.

• Cyrtoneurina Giglio-Tos, 1893 , Cyrtoneuropsis Malloch, 1925 , Neomuscina Townsend, 1919

The examined species of the above genera share the prevalent muscid state A 4 in which vein C is bare dorsally and extensively setulose ventrally: Cyrtoneurina (2 spp indet.), Cyrtoneuropsis (8 spp), Neomuscina rufoscutella Dodge, 1955 and N. tripunctata Wulp, 1896 .

• Arthurella Albuquerque, 1954

Among the two species examined, Arthurella nudiseta Albuquerque, 1954 has vein C extensively setulose dorsally (state A8), while A. choelensis Patitucci & Mariluis in Patitucci et al., 2011 is without dorsal setulae on CS1 (state A7).

• Pseudoptilolepis Snyder, 1949

The only examined species, P. confusa Snyder, 1949 , has vein C extensively setulose dorsally (state A8).
