﻿AbstractA new whitefly species,Aleurolobusrutaesp. nov., collected onMurrayaexotica(Sapindales,Rutaceae) leaves in the Maolan National Nature Reserve, Guizhou, China, is described and illustrated. Some of the individuals were infected withAschersoniaplacenta, 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 8thabdominal segment. Thoracic and caudal tracheal folds are discernible.
