Remarks: Actornithophilus ochraceus is a widespread species, showing some morphological variability among populations from different hosts ( Clay 1962: 202, fig. 1). Hence, we regard the Chilean population as “ sensu lato ”. This is the first record of Actornithophilus ochraceus from Chile, based on specimens held in NHML ( Shchedrina et al. 2017).
