Dendroptus olea sp. nov. is described from specimens collected on Canarium album (Lour.) Raeusch from Raoping, Guandong, China. The type specimens are deposited in the Collection of the Plant Protection Research Institute, Fujian Academy of Agricultural Sciences, Fuzhou, China. The male of this new species (figs. 1-6) is similar to Dendroptus ternifoliae Ochoa, 1991 in having dorsal median apodeme and four pairs of setae on propodosoma, and tibia IV with long solenidion, but it differs from the latter by (1) one pair of longitudinal apodeme and one pair of transverse apodeme located on tergite CD between setae c1 and d; (2) tarsus I with long solenidion; (3) tibia IV 3/5 as long as femorogenu IV. The adult female (figs. 7-12) is distinguishable from the know species of genus Dendroptus by (4) setae c2 with c1 in nearly transverse alignment; (5) poststernal apodeme connected with apodeme 4 forming inverted shape 'W'; (6) tibiatarsus IV with long solenidionφ 1.
