Three new species and four new records of the genus Aleuroclava Singh (Hemiptera, Aleyrodidae) from China, with the first description of seasonal dimorphism in the genus

Three new species of the genus <i>Aleuroclava</i> Singh viz., <i>A. bannanensis</i> <b>sp. nov</b>. (Yunnan: Xishuangbanna), <i>A. rubi</i> <b>sp. nov</b>. (Zhejiang: Hangzhou), and <i>A. yunnanensis</i> <b>sp. nov</b>. (Yunnan: Xishuangbanna) are described and illustrated. And four species of the genus, viz. <i>A. bifurcata</i> (Yunnan: Xishuangbanna), <i>A. citrifolii</i> (Yunnan: Xishuangbanna), <i>A. pearlis</i> (Yunnan: Xishuangbanna), and <i>A. stereospermi</i> (Yunnan: Pu'er) are new records to the known fauna of China. In addition, the seasonal dimorphism changes of <i>A. montanus</i> are recorded for the first time, and comments on its morphology are provided. This brings the number of Chinese species of <i>Aleuroclava</i> to 44. Images of the habitus, line illustrations, and scanning electron microscope photomicrographs are provided.
