SYNOPSIS. The obligate endoparasite of soil nematodes, described originally as Duboscqia penetrans Thorne, 1940, was proved to be incorrectly classified as a member of the genus Duboscqia (Protozoa, Microspora). Spores of this parasite were found to lack a polar filament, PAS‐positive polar cap, or any other features characteristic of the microsporan protozoa. The organism has a simple vegetative cycle within the host and its spore resembles the “endospore”common in Bacillus spp. It appears to have strong affinities to the etiologic agents ( Bacillus popilliae ) of the “milky disease”of certain insects.
