Distribution

Confirmed findings in Argentina, Brazil, Paraguay and Uruguay, concentrated in Pampa, Chaco, Cerrado, Atlantic Forest, Paraná Forest and Araucaria forest provinces.

Presence, established populations, habitat suitability and disease risk are distinct evidence categories.

Medical and veterinary relevance

Humans occur among reported hosts; this is biting evidence, not disease-risk evidence.

Rickettsia sp. strain Atlantic rainforest and strain COOPERI were molecularly detected in A. dubitatum collected in northeastern Argentina; detection alone does not establish field vector status.
