An updated checklist of mosquitoes (Diptera, Culicidae) of Ecuador: new records and public health significance
Mosquitoes are major vectors of human and animal diseases, making their accurate identification essential for vector surveillance and control. However, morphological identification has often been challenging, requiring taxonomic expertise and well-preserved specimens. Molecular markers, particularly DNA barcoding, offer an effective alternative for identifying both adult and immature stages. Ecuador is one of the most biodiverse countries in the world, a diversity that is also evident in its Culicidae fauna. This study provides a comprehensive revision of Ecuadorian mosquitoes, updating the national checklist and emphasizing species of public health importance. For species identification, an integrative approach was used combining morphology and DNA barcoding (COI and ITS2 regions). We list 266 species in 22 genera, of which 17 species are new national records, and 33 species are validated through molecular analysis. The updated checklist highlights Ecuador’s Culicidae diversity across its biogeographic regions, which represent 7% of the world’s mosquito diversity. These findings provide a critical foundation for future entomological research and vector control in the country.
