Abstract

Samsoniella species have been found on lepidopteran larvae or pupae buried in soil or leaf litter. Three new species, Samsoniella hymenopterorum, S. coleopterorum and S. lepidopterorum, parasitic on hymenopteran larvae, coleopteran larvae and lepidopteran pupae, respectively, are reported. Morphological comparisons with extant species and DNA-based phylogenies from analysis of a multigene (ITS, RPB1, RPB2 and TEF) dataset supported the establishment of the new species. Unusually, all three new species have mononematous conidiophores. The new species are clearly distinct from other species in Samsoniella occurring in separate subclades.
