Xenos gadagkari, Sen and Nain sp.nov.

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 .

FIGURE 17. A Baysian phylogenetic tree of partial mitochondrial CO1 sequences constructed using GTR+g+i model in MrBayes for different species of Xenidae family. X. gadagkari sequences generated for this study are represented in purple. Homologue from Stylops advarians (host: Andrena milawaukeensis) was used as an outgroup. Numbers above the nodes indicate clade credibility values. Names of the hosts and their family are given against the sequences. Host name was not available for X. hamiltoni in the paper associated with the accession number. However, X. hamiltoni is usually found in Polistes carnifex (Kathirithamby & Hughes, 2006).
