Résumé
The Yucatan Peninsula is a biogeographic province of the Neotropical region which is mostly encompassed by the 3 Mexican states of Campeche, Quintana Roo, and Yucatan. During the development of the International Joint Laboratory ELDORADO (Ecosystem, bioLogical Diversity, habitat modifications and Risk of emerging PAthogens and Diseases in MexicO), a French-Mexican collaboration between the IRD (Institut de Recherche pour le Developpement) and UNAM (Universidad Nacional Autonoma de Mexico) in Merida, it became evident that many putative mosquito species names recorded in the MexicanYucatan Peninsula were misidentifications/misinterpretations or from the uncritical repetition of incorrect literature records. To provide a stronger foundation for future studies, the mosquito fauna of the MexicanYucatan Peninsula is here comprehensively reviewed using current knowledge of taxonomy, ecology, and distribution of species through extensive bibliographic research, and examination of newly collected specimens. As a result, 90 mosquito species classified among 16 genera and 24 subgenera are recognized to occur in the MexicanYucatan Peninsula, including 1 new peninsula record and 3 new state records.
