This branching order is currently under examination and may be revised.

Countries where species of this subgenus are found: Bolivia, Brazil, Costa Rica, Colombia, French Guiana, Guyana, Panama, Peru, Suriname, Trinidad and Tobago and Venezuela.

The species in this subgenus are forest mosquitoes and to date have been poorly studied. Larvae and pupal forms have been found in shaded marshy and swampy areas along streams within forests. Adult females are known to feed on humans.

  • Abdominal setae 1 are vestigial or absent
  • Anterolateral spiracular lobes have a narrow finger-like process
