A new species of Aleuromarginatus Corbett, 1935 with a key and checklist of Chinese species (Hemiptera, Aleyrodidae).

A new whitefly species, Aleuromarginatus dielsianae Wang & Xu, sp. n. collected from Millettia dielsiana Harms (Rosales: Fabaceae) in Jiangshan (28°40'N, 118°40'E, 512 m) and Xinchang (29°22'N, 120°46'E, 308 m), Zhejiang, China, is described and illustrated. This new species is characterized by the dark brown lateral margin area and a pair of longitudinal furrows extending from the cephalothorax to the vasiform orifice. The submargin has an elongate-oval fold at the base of each marginal tooth and with 3-4 rows of irregular shaped papillae, nine pairs submedian setae and 13 pairs submarginal setae. Thoracic and caudal tracheal folds and pores discernible. An identification key and checklist of species of Aleuromarginatus known from China are provided. [ABSTRACT FROM AUTHOR]
