Recent urbanization in Macau has resulted in the precipitous decline to zero in populations of several anopheline vectors of malaria while providing optimal habitat for the population increase in culicines. Of 18 species of mosquitoes reported in Macau in recent years, 15 species are included here. Culex quinquefasciatus, Culex sitiens, and Aedes albopictus were the most abundant species. Notes are provided for Anopheles sinensis, Armigeres magnus, Armigeres subalbatus, Culex foliatus, Culex fuscanus, Culex infantulus, Culex rubithoracis, Culex sumatranus, Culex tritaeniorhynchus, Mansonia uniformis, Toxorhynchites splendens, and Tripteroides sp.
