Distribution
Western Hemisphere. Southernmost confirmed limit is Río Negro province, Argentina. Broader range includes South America; precise northern limits not specified in available sources.
Diet
Blood-feeding () on avian .
Host Associations
- Cyanoliseus patagonus - Burrowing Parrot, Psittacidae; of Cyanolicimex patagonicus in nest burrows
- Psittacidae - At least three Haematosiphoninae have documented associations with parrot
