During field surveys conducted in various regions of Thailand, several fungal specimens parasitising flies were discovered. These fungi exhibited morphological characteristics consistent with the broad concept of Ophiocordyceps dipterigena , including yellow to orange-brown cylindrical stromata bearing fertile ascomata at the tip. Multi-locus phylogenetic analyses based on ITS, LSU, TEF1 , and RPB2 sequences revealed that these specimens belong to a well-supported monophyletic clade, referred to as the ' O. dipterigena ' complex, which forms a distinct subclade within the hymenostilboid clade. This complex comprises four newly described species with clearly defined host associations: O. floriformis , found on robber flies (Asilidae), particularly on Clephydroneura sp.; O. muscae , isolated from the housefly ( Musca domestica ); O. tabani , parasitising horse flies ( Tabanus sp.); and O. thilosuensis , infecting fruit flies ( Anastrepha obliqua ) and soldier flies (Sarginae). Additionally, several strains clustered with the previously described O. philippinensis , which was also collected from Clephydroneura sp. This marks the first record of O. philippinensis in Thailand.
