This species has been lacking a detailed and formal description. In past years we collected a male and four females of this species from Yunnan, China.In this paper, we describe both the adult male and female of this species in detail, especially providing diagnostic features of the antenna, ventrite and male aedeagus. We provide photographs of the dorsal and ventral view, habitat of both male and female adults, and figures detailing the diagnostic features of both male and female antenna, male abdominal ventrites and the male aedeagus. In addition, we discuss one intraspecific variation found in this species. This provides an important basis for correct identification of this species.展开更多

Two species of whitefly （Hemiptera： Aleyrodidae）, Aleuroclava ayyari （Sundararaj ＆ David） and Aleurotrachelus grewiae Takahashi, new to the known fauna of China, are redescribed with morphological illustrations ...Two species of whitefly （Hemiptera： Aleyrodidae）, Aleuroclava ayyari （Sundararaj ＆ David） and Aleurotrachelus grewiae Takahashi, new to the known fauna of China, are redescribed with morphological illustrations and photographs from a scanning electron microscope （SEM）. A. ayyari is characterized by the presence of two pairs of long subdorsal setae on the cephalic region and first abdominal segment. A. grewiae is characterized by the pupa case sclerotized, pointed at both ends and the base of abdomen rounded at the middle. Specimens are deposited in the Insect Collection of Yangzhou University.展开更多

Eleven species of this genus are known in China. The new Chinese record species are: L. brancuccii Schawaller, 2013, L. kaszabi Schawaller, 1997 and L. rugosissimus Kaszab, 1980. A key to the known Luprops species and its morphological details are provided. In addition, larva of Luprops horni(Gebien, 1914) is reported for the first time.展开更多

But until now, no water mites have been recorded from Tibet. In this study, two water mite species, Sperchon glandulosus Koenike, 1886 and Sperchon plumifer Thor, 1902 are reported for the first time from Tibet, and Sperchon glandulosus is newly recorded from China. Descriptions and illustrations of Sperchon glandulosus are given herein. DNA barcodings for the two species are also referenced. A key to the 22 species（females） in the genus Sperchon from China is presented.展开更多
