Eubacterial cellular endoparasites belonging to the genus Wolbachia (Rickettsiales) are extremely widespread symbionts of Arthropoda and Nematoda. Their ability to manipulate the reproductive behavior of the host is of particular importance to the fauna of the deep soil horizon, an environment in which parthenogenesis-inducing symbionts can play a crucial role in shaping population dynamics and speciation processes. In this study, three novel cases of infection in parthenogenetic Collembola (Parisotoma notabilis, Neelus murinus and Megalothorax minimus) are described. Sequences for molecular markers 16S rDNA and ftsZ were obtained for each species; their phylogenetic affinities with known Wolbachia supergroups were established using Bayesian inference. The analysis confirmed the presence of a Wolbachia strain belonging to the supergroup E, already reported from Folsomia candida and the Tullbergiidae, in the isotomid P. notabilis, while the Neelipleona M. minimus and N. murinus host a well differentiated strain which is phylogenetically distinct from supergroup E. Multiple events of Wolbachia infection in springtails as well as a richer diversity of the symbiont strains in soil arthropods were hereby confirmed.
