Conidiobolus obscurus and C. thromboides (Zygomycetes: Entomophthorales), aphid-attacking fungi, were found on the Dactynotus species (Homoptera: Aphididae) in June 1998 for the first time in Korea. They produce globose primary conidia typical to the genus Conidiobolus but their dimensions are clearly distinguished. Conidiobolus thromboides produces rhizoids and conidiophores with cylindrical constriction at their apices but C. obscurus does not form rhizoids or constricted conidiophores. Resting spores were not found in our specimens of both species, but their vegetative structures observed readily allowed identification.
