Molecular Phylogenetic Affinities of Endangered Trombidium Grandissim Using Mitochondrial 16S RDNA Sequence

Molecular phylogenetic analysis has become a valuable tool for inferring speciesevolutionary relationship amidst the taxa. The majority mites of the family Trombidiidae are ectoparasites in the larval phase and free-living predators in the deutonymphal and adult phases on a variety of arthropods. We have collected sample Trombidium grandissimum from Andhra Pradesh and built a molecular phylogeny of Trombidiidae and Acari taxa from across its distribution using 16s ribosomal rDNA gene to infer the phylogenetic affinities among the subclass Acari, whether the sample from Andhra Pradesh are nested and also perceive the T. grandissimumis more closely related to the conspecifics from the Indian subcontinent or otherwise. Our consequences show the family Trombidiidae have formed cluster with the monophyletic families namely Demodicidae also indicating that the Trombidiidae families are closely related to the representatives of Demodicidae families as descend under the subclass Acari.
