ABSTRACT. In Mexico, Aedes podographicus is one of the most common species within the subgenus Protomacleaya of Aedes. This species has been collected in 12 states close to the coastal regions; however, few records confirm the presence of Ae. podographicus inland. During a mosquito-survey using ovitraps in the state of Nuevo Leon,´ Mexico, Ae. podographicus was collected in association with Ae. albopictus and Culex Downloaded from http://meridian.allenpress.com/jamca/article-pdf/37/2/87/2855378/i8756-971x-37-2-87.pdf by guest on 25 September 2021 quinquefasciatus. This is the first record of the presence of Ae. podographicus in Nuevo Leon.´ With the addition of Ae. podographicus to the mosquito fauna of Nuevo Leon,´ there are currently 66 species in the state, 19 within the genus Aedes and 6 within the subgenus Protomacleaya, the genus Aedes being the group with the major number of species in Nuevo Leon.´ Specimens collected during this study were deposited in the collection of insects and mites of medical importance of the Laboratory of Medical Entomology of the Autonomous University of Nuevo Leon,´ Mexico.

The subgenus Protomacleaya of Aedes is divided and Vargas (1973) reported this species in the states into 4 nominal groups: the Knabi, Kompi, Terrens, of Campeche, Nayarit, Oaxaca, and Sonora, and and Triseriatus groups; all groups include species Heinemann and Belkin (1977) in the states of occurring in Mexico, and most species of those Oaxaca, Campeche, Sonora, Sinaloa, Nayarit, and groups develop their immature stages in tree holes Jalisco. Recently, Ae. podographicus was collected while some species also have been found in artificial for the first time in the states of Quintana Roo containers. In Mexico, the Terrens group includes 12 (Ortega-Morales et al. 2010), Guerrero (Ortega- species: Ae. amabilis Schick, Ae. diazi Schick, Ae.
