Fungal pathogens occurring on in Thailand.

Two new fungal genera and six species occurring on insects in the orders Orthoptera and Phasmatodea (superorder Orthopterida) were discovered that are distributed across three families in the . Sixty-seven sequences generated in this study were used in a multi-locus phylogenetic study comprising SSU, LSU, , and together with the nuclear intergenic region (IGR). These new taxa are introduced as , , , , and . shows resemblance to by infecting egg cases (ootheca) of praying mantis (Mantidae) and having obovoid perithecial heads but differs in the size of its perithecia and ascospore shape. Two new species in the cluster belonging to the complex are described that differ from known species with respect to phialide size, conidia and host. resembles in the absence of a stipe and can be distinguished by the production of whole ascospores, which are not commonly found in (except in , which produces multiseptate, whole ascospores) is pathogenic to mole crickets and shows resemblance to , and in having darkly pigmented stromata. occurs on small crickets, and is the phylogenetic sister species of taxa in the 'sphecocephala' clade.
