Illustrated keys to the mosquitoes of Thailand I. Background; geographic distribution; lists of genera, subgenera, and species; and a key to the genera.

This is the first of a series of six sections that will cover 436 species of mosquitoes currently known to occur in Thailand. In this section we provide information on the background, geographic distribution, bionomics, lists of genera, subgenera, and specie of mosquitoes that occur in Thailand, and a key to the genera. The sections, listed below will be published as separate supplements in following issues of this journal: II. Key to the Culex; III. Key to the Aedeomyia, Ficalbia, Mimomyia, Hodgesia, Coquillettidia, Mansonia, and Uranotaenia. The additional 3 supplements consisting of the Key to the Tribe Aedini; Key to the Anopheles; and the Keys to the Armigeres, Heizmannia, Orthopodomyia, Malaya, Topomyia, Tripteroides, and Toxorhynchites will be published as they are completed. At the conclusion of this project, one large supplement to the Southeast Asian Journal of Tropical Medicine and Public Health will be produced that includes all of these keys in a single document.
