Abstract
The calliphorid flies collected from different localities in Thailand were examined to study their medical importance as well as to study from the zoogeographical standpoint of view. Fourty-two species of 15 genera, Bengalia，Calliphora, Catapicephala, Chrysomya, Hemipyrellia, Hypopygiopsis, Lucilia, Melinda, Onesia，Phumosia，Pollenia, Polleniopsis, Tainanina, Tricycleopsis and Verticia belonging to both the subfamilies Calliphorinae and Chrysomyinae were found in Thailand. Many species are newly recorded from this country. The little known species, which are redescribed in detail with the illustration of the male genitalia and female ovipositors, and the key, which is revised to the gene1a and species, are also presented in this paper.
