Key Points

To identify and characterize Anopheles species complexes involved in malaria transmission in Guyana and Venezuela.
Utilized COI sequencing to identify Anopheles species
Conducted field surveys in malaria endemic areas
Compared findings with existing literature on Anopheles in the region
First report of Anopheles goeldii from Guyana and Venezuela
First identification of Anopheles oswaldoi A in Venezuela
Confirmation of Anopheles albitarsis F as the only member of its complex prevalent in Venezuela

Abstract

Anopheles goeldii is reported for the first time from Guyana and Venezuela, and discuss its role as vector of malaria parasites in both countries and its relative recent colonization. Anopheles oswaldoi A is reported for the first time from Venezuela. Anopheles albitarsis F, an important malaria vector in Colombia and Venezuela, is confirmed as the only species of the Albitarsis complex widely distributed in Venezuela. Our results will be valuable for future research aimed at clarifying the status of these significant species complexes in the region.
