Among the multiple groups that compose the Spissipes and Melanoconion Sections of the subgenus Melanoconion of Culex, the Atratus and Educator Groups present species that are involved in the transmission of arboviruses to man and animals in rural and wild environments. However, these groups present great difficulty in identifying the species, either because of the great morphological similarity between their representatives or the lack of updated identification keys. The aim of this study was to carry out a taxonomic review of the species belonging to the Atratus and Educator Groups of the Melanoconion Section of Culex (Melanoconion). Therefore, a detailed morphological study of the several stages of development of the specimens of interest was carried out, verifying the existence of species to be named and/or valid species placed in the synonymy of others. As a result of the morphological study of the Atratus Group species, eight species were redefined. Of these, two were resurrected from the synonymy of others and six species unknown to science were described and will be formally named. For the Educator Group, eight species have been described, one being removed from the synonymy and three species unknown to science have been described and will be formally named. Illustrated identification keys, with characters used for species recognition, have been created for all forms of development of species in both Groups. Geographic distribution maps of the species were created, illustrations and photographic plates for comparison of external morphological structures of the immatures forms, adults and male genitalia were provided, and bionomic data were updated.
