Phylogenetic analysis The phylogenetic analysis of X. gadagkari was conducted with several partial fragments of the mitochondrial COI gene sequences of other species obtained from NCBI. X. gadagkari forms a clade with X. vesparum among several other strepsipterans from different Polistine wasps ( Fig 17 ). The clade is also supported by high posterior probabilities (100) indicating strong reliability of the clade. The X . gadagkari sequences show a synonymous site divergence of 79% (with 68% divergence across all the sites considered) from X. vesparum .
