Materials Examined
Type data Holotype, female, from Populus sp. (Salicaceae), Baiyun (33 ° 39.86 ’N, 111 ° 49.58 ’E), Song County, Henan Province, P. R. China, 17 July 2004, coll. X.F. Xue. Paratypes, 11 females and 3 males, with the same data as holotype.
Relation to host Vagrant on leaf surface. No damage to the host was observed.
Etymology
Etymology Derived from the generic name of the type host plant, Populus.
Discussion
Remarks This species is similar to Acaphyllisa cryptomeria Huang, 2001 (Huang, 2001), but can be differentiated by coxal plates with granules (smooth in A. cryptomeria), dorsal opisthosoma with elliptical microtubercles (with spiny microtubercles in A. cryptomeria) and with different prodorsal shield design.
Distribution
Distribution China (Henan).
