Contribution to our knowledge of the whitefly genus Aleuroclava Singh (Hemiptera: Aleyrodidae) in China, including Taiwan and Hong Kong, with descriptions of two new species

Two new whitefly species, Aleuroclava sterculiae sp. nov., collected from Sterculia nobilis (Malvales: Sterculiaceae) of Qingxiu hill park (Guangxi, China), and Aleuroclava rosae sp. nov., collected from Stranvaesia sp. (Rosales: Rosaceae) of Maoer Mountain (Guangxi, China), are described with morphology, line illustrations, photographs and scanning electron microscope (SEM) images. In addition, two other whitefly species, Aleuroclava lefroyi (Sundararaj & David) and Aleuroclava manii (David), are reported as new to the fauna of China, and are discussed. An identification key to Aleuroclava species known from Mainland China, Taiwan and Hong Kong is provided. The specimens are deposited in the Insect Collection of Yangzhou University (YZU).
