Chagasia
Chagasia is one of the three mosquito genera in the subfamily Anophelinae. The other two genera are "Anopheles" Meigen (nearly worldwide distribution) and "Bironella" Theobald (Australia only). The subfamily consists of five species in the Neotropical region. These include "C. ablusa" Harbach, "C. bathana" Dyar, "C. bonneae" Root, "C. fajardi" Lutz and "C. rozeboomi" Causey, Deane & Deane. "Bironella" appears to be the sister taxon to "Anopheles", with "Chagasia" forming the outgroup in this subfamily. The species "Chagasia bathana" has 8 chromosomes and males are heterogametic with one long X chromosome and one short Y chromosome.
