A new species of Isaria isolated from an infected locust

Isaria locusticola sp. nov. was isolated from a locust in Fuzhou, Fujian Province, China. The new species is described and illustrated, and its relationships to the related species are briefly discussed. This fungus is characterized by the variability of the shape of conidia. Morphological characteristics and molecular analyses of ITS-5.8S region sequences strongly support the establishment of I. locusticola in the genus Isaria.
