Other significant references: Cummings (1916); Clay & Hopkins (1960); KÉler (1960); Złotorzycka (1970); Palma (1996: 155); Price et al. (2003); Martín-Mateo (2009: 213); Palma (2010); Palma & Peck (2013: 28); Grossi et al. (2014: 602, figs 1B, 2); Palma (2017).

Remarks: Many subspecies of Anatoecus icterodes have been described (see Price et al. 2003: 146), but their type hosts are not Chilean hosts. Therefore, until a detailed revision of the Chilean populations of A. icterodes is available, we regard them as “ sensu lato ”.

A molecular study by Grossi et al. (2014) concluded that Anatoecus icterodes is a junior synonym of A. dentatus . However, since the many subspecies names assigned to these two species have not been reviewed, and considering that records of Chilean Anatoecus have not been yet formally synonymised, we maintain both species as valid.
