The systematic status of the genus Summersiella Gonzalez is reviewed and a revised definition is proposed. A new species, Summersiella camphorae, from the leaves of camphor tree (Cinnamomum camphora) in Fujian Province of China, is described and illustrated. This new species is distinguished from the only known species, Summersiella coprosmae (Wood), by having an apparently sclerotized hexagonal central hysterosomal shield with five pairs of setae; by having much shorter dorsal setae (ve not exceeding base of sci); by the following ratios: vi/vi-vi = 0.7, ve/ve-sci = 1.0; and by the length of solenidion w on tarsus I (19–21 µm).
