A Study On The Classification Of Deraeocorinae (Hemiptera-Heteroptera) From Inner Mongolia, China

In this paper, the author studied the classification of Deraeocorinae Douglas & Scott, 1865(Hemiptera: Heteroptera: Miridae:Deraeocorinae, including its species, morphology, distribution, host, dissect and compare of genitalia, fauna etc.), from Inner Mongolia, China. 17 species were found, belonging to 2 tribes, 3 genera of Deraeocorinae. Among them, 2 new species (Deraeocoris nigrorum sp.nov. , Deraeocoris desertorum sp.nov.) were described and some species of Deraeocorinae from Inner Mongolia were revised. The male's genitalia, phallus opening and antenna of 17 species as well as shapes of the new species were figured. The faunistic analysis of Inner Mongolia Deraeocorinae displayed that the Palaeartic species dominate among all species. The species only belonging to Palaeartic occupy 76.47 %. In China, most of Deraeocorinae distribute in Northern-East, Northern-China and Mongolia-Xinjiang regions. The species belonging to Northern-China (15) are the first, occupying 88.24 %. The species of Mongolia-Xinjiang(11), Northern-East(10) are second, they occupying separately 64.71% and 58.82%.
