Following the previous report on the comparative study of pleural structures of the thorax of adult mosquitoes in Japan, additional observations were made with 31 species of the mosquitoes collected from Thailand. It was also confirmed that the characters of pleural plates and attached bristles and scales were extremely useful in the taxonomy of the mosquitoes. Taxonomical key characters were described and illustrated for identification and classification of the species, subgenera, genera and tribes of the family Culicidae. The examination of pleural structures by the method reported here is recommended to be more widely used in the entomological surveys, since it is simple and easy to be practiced in the fields, and always reflects phylogenetically important charcters.
