A new species of Aleurolobus Quaintance & Baker, 1914 (Hemiptera, Aleyrodidae) from China infesting Murraya exotica L.

A new whitefly species, Aleurolobus rutae sp. nov., collected on Murraya exotica (Sapindales, Rutaceae) leaves in the Maolan National Nature Reserve, Guizhou, China, is described and illustrated. Some of the individuals were infected with Aschersonia placenta, an entomopathogenic fungus. The insect is circular in shape and characterized by a very wide submarginal region, and the submarginal furrow is almost continuous, with only a small break at the caudal furrow. Anterior and posterior marginal setae are absent, but setae are present on the 8^th abdominal segment. Thoracic and caudal tracheal folds are discernible.
