A new genus belonging to the tribe Opsiini (Hemiptera: Cicadellidae) from India and its molecular phylogeny.

The new leafhopper genus gen. nov., sp.

Tribe reassessment of the subhimalayan leafhopper genus (Homoptera: Cicadellidae) based on molecular phylogeny.

The phylogeny of the were investigated using of two different data sets, including 91 taxa and 3853 aligned nucleotide positions from the histone , rDNA (D2 & D9-10 region). The results suggest the placement of genus in the tribe Ciacadulini, as it was clustered with Cicadulini genera. Relationships between genera of the Cicadulini were strongly supported and leads placement to tribe Cicadulini from Athysanini.

First record of the leafhopper genus Xenovarta Viraktamath (Hemiptera, Cicadellidae, Deltocephalinae) from India with description of a new species.

The genus Xenovarta Viraktamath is recorded from India for the first time and Xenovarta viraktamathi sp. nov. from India is described and illustrated.

Assessment of bacterial endosymbionts and the host, (Hemiptera: Aleyrodidae), using rRNA and mitochondrial cytochrome oxidase I gene sequences.

Endosymbionts are vital factor for arthropod ecology. The whitefly (Hemiptera: Aleyrodidae) is a cryptic species complex composed of more than 34 putative species. Moreover to the primary endosymbiont , six secondary endosymbionts , , , and are known in .
