A Preliminary Study On The Classification Of Flower Bugs (Hemiptera-Heteroptera) From Inner Mongolia-Xinjiang Region, China

The author have studied the taxology of flower bugs (Hemiptera- Heteroptera: Anthocoridae Lyctocoridae) from Inner Mongolia– Xinjiang Region, refering to species, distribution, morphology, Fauna etc. In this paper, the author have identified 31species, belonging to two family, four tribes, eight genera, including six new species (Xylocoris obscurus sp. nov., Tetraphleps dolichorostrus sp. nov., Tetraphleps maculatus sp. nov., Tetraphleps alashanensis sp. nov., Tetraphleps leucolineatus sp. nov.,Anthocoris gansuensis sp. nov.), two Chinese firstly recorded species (Orius sibiricus Wagner, Orius laticollis laticollis (Reuter)). Copulatory tube of two species (Orius neimongolanus Bu et Zheng, Orius sibiricus Wagner) were described. The ostiolar peritreme, male genitalia, female copulatory tube or seminal conceptacle of flower bugs were figured. Dorsal view of new species and Chinese firstly recorded species were figured too. The faunistic analysis of Inner Mongolia– Xinjiamg Region flower bugs displayed that the Palaeartic species dominate in all species. The species only belonging to Palaeartic occupy 64.51 percent. The rest was shared by Palaearctic and Oriental, Palaearctic and Nearctic or Palaearctic, Oriental and Nearctic. In China, the Inner Mongolia– Xinjiang flower bugs were rich in Northen-China, Central-China and Northen-East, respectively account for 45.16, 22.58, 19.35 percent. In Inner Mongolia– Xinjiang Region, Eastern Steppe Subregion with the most species, while Tianshan Mountain Subregion with the least species.
