An interesting question. According to an old edition of
Chandler and Read: 

Chagas first discovered the disease in 1909 in the State of 
Minas Gerais, Brazil. Found all the way from the pampas of
Argentina to the deserts and canyons of southern California
and Arizona; scrub woods and farms in southern Texas;
isolated from raccoons in Maryland; a similar parasite isol.
in Asiatic monkeys! A closely related species T. vespertilonis
occurs in bats worldwide.  Formerly called Schizotrypanum
cruzi. In the original Brazilian discovery it was found
vectored by a large blood-sucking bug Panstrongylus megistus.
Other Triatominae bugs involved. 
I hope this helps. Looking for more recent data and will
advise you ,if found.
