Akanthomyces koratensis ≡ Akanthomyces koratensis Hywel-Jones, Mycol. Res. 100: 1068 (1996).

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.

Figure 1. RAxML tree of Hevansia, Jenniferia, Parahevasia, Polystromomyces and related genera in the Cordycipitaceae from a combined ITS, LSU, tef 1, rpb 1 and rpb 2 dataset. Numbers at the major nodes represent Maximum Likelihood Bootstrap (MLB) and Bayesian Posterior Probabilities (BPP). Bold lines in the tree represent 100 % of MLB and 1.00 of BPP. Symbols on the right-hand side correspond to the types of ascospore morphologies found in each genus that are observed in natural specimens of Cordycipitaceae described in Fig. 2.
