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

Intrapredatorus barri, a microsporidian parasite of the predator mosquito C ulex fuscanus Wiedemann has been shown to be heterosporous. In many feature s this species has been reported to be similar to Ambylospora trinus, anoth er microsporidian parasite of a different predator mosquito which was thus proposed for reassignation to the genus Intrapredatorus. In this report sma ll subunit rDNA has been sequenced from I. barri and phylogenetic analysis of 12 microsporidia sequences has been performed. The molecular data show t hat I. barri can not be a member of the genus Amblyospora. Furthermore, the phylogenetic analysis shows, With high confidence, that the Ambylospora sp p. sequences in the present study are not monophyletic.
