Brachystomatidae ( Fig. 50–51 )

The Brachystomatidae comprises more than 155 species, grouped into three subfamilies and 22 extant genera ( Sinclair 2017a). Sinclair & Cumming (2006) conducted a morphological cladistic study and separated the superfamily Empidoidea into five families, one of which is Brachystomatidae . The fauna of the family in Chile is particularly rich and diverse. This includes large and minute species recently described such as Gondwanodromia mikae ( Sinclair & Saigusa 2022) . Moreover, Gondwanamyia chilensis Cumming & Saigusa ( Sinclair et al. 2016) has been suggested that it could belong to this family due to the morphological characteristics of the female terminalia, placing it within Trichopezinae . The current fauna for this family accounts for 37 species in six known genera ( González et al. 2021a; Sinclair & Saigusa 2022).
