Abstract:

In this paper, a new species, Zaraea mengmeng Yan, Li & Wei sp. nov. (Hymenoptera:Cimbicidae), collected from the Mt. Tianmu, Zhejiang Province, China, is described. Its larvae feeding on leaves of Padus brachypoda and could defoliate entire leaves of the host tree with high density, which will affect its growth, thus affecting the yield of fruit trees and seriously reducing the economic benefits of trees. The new species develops one generation a year in the Mountains and overwinters in the form of pre-pupa. This new species is very similar to Z. akebiae, but can be distinguished from the latter by the following characters:metanotum and abdominal tergum 1 entirely yellowish white; tibia and tarsus of each leg dark brown; the ventral half of mesepisternum smooth and sparsely punctured. The genomic DNA of the new species was extracted using the DNeasy Tissue Kit (Qiagen, Valencia, CA), 12 sequences of Cytochrome oxidase Ⅰ(COⅠ) (2 sequences of the new species and 10 sequences of other species of Cimbicidae were obtained from the mitochondrial gene, with a length of 850 bp; In addition, we downloaded 23 COⅠ sequences of known Cimbicidae and related genera species used in previous phylogenetic analyses from GenBank database, which constitute the CO Ⅰ sequence data set with the new species sequence (35 samples in total). The genetic distance of Abiinae was analyzed and the results showed that the genetic distance is 0.005 between two samples of the new species. Each of the clade Zaraea, Orientabia and Abia, are recovered as a monophyletic group, with high support for the BI trees (Posterior probability >0.96). We suggest that Zaraea, Orientabia and Abia are three valid genera of Abiinae. Results of molecular analysis of the new species are consistent with those of morphological identification, which supports the establishment of new species.
