Nemestrinidae ( Fig. 31 )

The Nemestrinidae comprises 275 species, grouped into five subfamilies and 23 extant genera ( Bernardi 1973; Woodley 2009). Bernardi (1973) divided the family into five subfamilies, Atriadopsinae, Cyclopsideinae, Hirmoneurinae, Nemestrininae and Trichopsideinae. Papavero & Bernardi (2009) corrected the names of the subfamilies Atriadopinae and Falleniinae and replaced them with those of Atriadopsinae and Trichopsideinae, respectively. The knowledge of the family in the country is largely based on the works of Stuardo (1932, 1934, 1936) and Angulo (1971). For Chile, 39 species are grouped in four genera, Hyrmophlaeba Rondani , Hirmoneuropsis Bequaert, Neorrhyncocephalus Lichtwardt , and Trichophthalma Westwood ( Papavero & Bernardi 2009) . An updated catalog of Chilean nemestrinids has been published by González et al. (2023a).

B. Section Heterodactyla

This monophyletic group contains all Brachycera flies with a reduced or absent tarsal empodium, although both characters are homoplasious ( Shin et al. 2018).
