The collection of Sarcophagidae made by the first author during the surveys on flies of medical and forensic importance in Thailand from 2012 to 2016 is dealt with. A total 31 genera and 86 species of the flesh flies are listed. One new genus Komisca gen. nov. is established for Sarcophaga (s. lat.) nanensis Chaiwang, Sukontason & Sukontason, 2009. One little known species, Burmanomyia aureomarginata (Shinonaga & Tumrasvin, 1979) n. com., is redescribed and illustrated. Revised identification keys to the species of Thai Sarcophagidae are provided to include the new genus and three newly recorded species discovered after the last work (Kurahashi & Chaiwong, 2013). General morphology, terminology and definition are provided for keys and redescription.
