Xylophagidae ( Fig. 20 )

The family comprises over 134 species in 11 extant genera ( Woodley 2011). Only Heterostomus curvipalpis Bigot ( Woodley 2011) is known from Chile ( James 1975b). Coscarón et al. (2013) described the puparium of this species.

2. Infraorder Tabanomorpha

The molecular analysis of Wiegmann et al. (2011) indicated that the Tabanomorpha should include the families Rhagionidae , Pelecorhynchidae , Tabanidae , Austroleptidae , Athericidae , Bolbomyiidae , Oreoleptidae and Vermileonidae , with the latter three absent from Chile. The monophyly of this infraorder is suggested by the presence of the first expanded ventrolateral cercal segment in females, bulbous clypeus of adults, a brush on the larval mandible and the retractile head capsule of the larva ( Wiegmann et al. 2000; Kerr 2010; Morita et al. 2016; Wiegmann & Yeates 2017).
