Res. 100: 1068 (1996). Hevansia koratensis ≡ Hevansia koratensis (Hywel-Jones) Luangsa-ard, Hywel-Jones & Spatafora, IMA Fungus 8: 349 (2017). Typification. Thailand, Nakhon Ratchasima Province, Khao Yai National Park, 14°26'20.72"N , 101°22'20.02"E , on spider ( Araneae , Salticidae ), 12 December 1991, N.L. Hywel-Jones, NHJ 666.01 holotype. Description and illustration. See Hywel-Jones (1996) . Host. Spider ( Araneae , Salticidae ). Habitat. Specimens were found on the underside of dicot leaves of forest plants. Notes. Both Parahevansia koratensis and H. novoguineensis occur on spiders and both produce white mycelium with reddish pigment diffusing in agar media ( Hywel-Jones 1996 ). However, the sporulation of H. novoguineensis is produced on media, while no sporulation on media in Pa. koratensis was observed. Based on the phylogenetic tree (Fig. 1 ), NHJ 2662 clustered with the ex-type strain NHJ 666.01 of Pa. koratensis . The insect host of the strain NHJ 2662 was recorded as a Lepidoptera larva. This result shows that Pa. koratensis is parasitic on spiders and Lepidoptera larva.
