DNA Barcoding and Molecular Phylogenetics Revealed a New Cryptic Bamboo Aphid Species of the Genus <i>Takecallis</i> (Hemiptera: Aphididae)

Abstract

Takecallis nigroantennatus Wieczorek sp. nov. (Hemiptera: Aphididae), associated with the cold hardy bamboo variety Fargesia spp. (Bambusoideae), is described and illustrated along with a key to species of the genus Takecallis. The results of a mitochondrial COI (DNA barcoding) and nuclear elongation factor 1 (EF1α) gene sequences, which confirm the genetic difference of the new taxon from the other congeneric species, are provided. The possible way of introduction of this species to Europe is discussed with its new locality from Belgium.
