Durante a pesquisa anual de moscas em Doi Nang Kaew no Distrito de Doi, Província de Chiang Mai, Thailandia, em 2011, Isomyia paurogonita Fang e Fan, 1986 (Diptera: Calliphoridae) e Sumatria latifrons, Malloch, 1926 (Diptera: Calliphoridae) foram coletados pela primeira vez na Tailândia. São espécies raras da sub-família Rhiniinae (tribo Cosminini). Antes deste achado, 15 espécies de Isomyia e duas de Sumatria foram relatadas na Tailândia. Portanto, 96 espécies de ”blow flies” foram encontradas neste país. Estes achados locais de ambas as moscas são bastante importantes para a posterior pesquisa de sua biologia e ecologia na Tailândia.

During the annual fly survey at Doi Nang Kaew in Doi Saket District, Chiang Mai Province of Thailand in 2011, Isomyia paurogonitaFang & Fan, 1986 (Diptera: Calliphoridae) and Sumatria latifrons Malloch, 1926 (Diptera: Calliphoridae) were collected for the first time in Thailand. They are the rare species of the subfamily Rhiniinae (tribe Cosminini). Prior to this finding, fifteen species of Isomyia and two species of Sumatriawere recorded from Thailand. Therefore, 96 blow fly species have been found in this country. These new locality records of both flies are very important for further research on their biology and ecology in Thailand.

BACKGROUND: Although tropical climate of Thailand is suitably endowed with biodiversity of insects, flies of medical importance is not well investigated. Using information from literature search, fly survey approach and specialist's experience, we review database of Sarcophaga (Liosarcophaga) dux Thomson (Diptera: Sarcophagidae), one of the priorities flesh fly species of medical importance in Thailand. RESULTS: This review deals with morphology, bionomics and medical involvement. Important morphological characteristics of egg, larva, puparia and adult were highlighted with illustration and/or micrographs. Search pertaining to molecular analysis used for fly identification and developmental rate of larvae were included. Medical involvement of larvae was not only myiasis-producing agent in humans and animals, but associated with human death investigations. CONCLUSIONS: This information will enable us to accurate identify this species and to emphasis the increase medically important scene in Thailand.
