Ragadidae

Ragadidae comprises 31 species (including two fossils) in five genera (Sinclair 2016; Pape & Thompson 2020). Wahlberg & Johanson (2018) elevated Ragadidae to family level. For Chile, two genera and two species are reported, Hydropeza curicoa Sinclair & Plant and Dipsomyia spinifera Bezzi ( Sinclair & Plant 2008; Sinclair 2016; Wahlberg 2019).

D. Section Cyclorrhapha

This taxon is divided into two sections: Aschiza,which is paraphyletic,and Schizophora,which includes allAcalyptratae superfamilies, and the Calyptratae, which is divided into 13 families. The most prominent autapomorphies in this group are the loss of the larval head capsule and pupation of third-instar larval skin ( Wiegmann & Yeates 2017).

Division Aschiza. This group in Chile is composed of six families, 76 genera and 210 valid species ( Table 3). The group includes two clades: Platypezoidea and Syrphoidea . Some authors suggest that the Pipunculidae are sister to Schizophora, and not to Syprhidae (see, for example, Pauli et al. 2018). No catalogs of the four platypezoid families ( Opetiidae , Lonchopteridae , Phoridae , and Platypezidae ) were included in CDASUS. The aschizan genera and species have increased by 117.14% (n = 41) and 114.28%, respectively (n = 112).
