Phylogenetic Relationships in Rhinonyssid Mites (Acari: Rhinonyssidae) Based on Mitochondrial 16S rDNA Sequences
2001
A 390 bp region of the 16S rDNA gene was sequenced from six species ofrhinonyssid mites (Tinaminyssus columbae, T. minisetosum, Sternostomaturdi, S. sternahirundo, S. fulicae and Ptilonyssus euroturdi) andtwo subspecies (Tinaminyssus melloi melloi andTinaminyssus melloi streptopeliae) to examine the level ofsequence variation and the taxonomic levels to show utility in phylogenyestimation. Furthemore, two different geographic locations of T. m.melloi and T. m. streptopeliae were analyzed todetect variation between populations. Molecular data revealed the existence oftwo distinct groups in the genus Tinaminyssus parasitic oncolumbiform birds. These results are in agreement with those reported by someauthors using morphological characters. Sternostoma turdi parasitizing aerial birds appeared to be phylogenetically separated from otherspecies of this genus isolated from aquatic birds. Moreover, our studyaddressesthe validity of the subspecies status of T. melloistreptopeliae. This region of the mitochondrial 16S rDNA gene is auseful marker for inferring phylogenetic relationships among closely relatedrhinonyssid species, but not for more distantly related taxa.
