rDNA phylogeny of Intrapredatorus barri (Microsporida: Amblyosporidae) parasitic to Culex fuscanus Wiedemann (Diptera: Culicidae).

Intrapredatorus barri, a microsporidian parasite of the predator mosquito Culex fuscanus Wiedemann has been shown to be heterosporous. In many features this species has been reported to be similar to Amblyospora trinus, another microsporidian parasite of a different predator mosquito which was thus proposed for reassignation to the genus Intrapredatorus. In this report small subunit rDNA has been sequenced from I. barri and phylogenetic analysis of 42 microsporidia sequences has been performed. The molecular data show that I. barri can not be a member of the genus Amblyospora. Furthermore, the phylogenetic analysis shows, with high confidence, that the Amblyospora spp. sequences in the present study are not monophyletic.
