Eriosomatinae — Pemphigini

Ceratopemphigus zehntneri Schouteden (1905)

Three HK samples in BMNH, all from galls on Ligustrum sinense . One sample was collected by Hill at The Peak and another anonymously collected at TLF, with both samples being sent to CIE in 1974 and initially determined as Prociphilus sp. , that determination communicated back to the sender and the record being quoted by Lee & Winney (1981) as? Prociphilus sp .. The corrected determination for these 1974 samples was by Eastop. The third, large, sample in BMNH was collected by the second author from L. sinense at TLF and sent to the IIE in 1991: this was determined as Prociphilus ligustrifoliae (Tseng & Tao, 1938) . However, the alatae of this third sample do not match those of P. ligustrifoliae from Japan and Korea in BMNH, but do closely agree with other material of C. zehntneri , including syntypes from Sri Lanka and the two 1974 HK samples. Cock et al. (2010) provided a detailed treatise on the most interesting biology of this species, based on an observed population on Ligustrum robustum subspecies walkeri in Sri Lanka. The second author has compared his photographs of galls of the 1991 HK sample with photographs in the Cock et al paper, concluding that there is great similarity. From the morphology of the alatae and the features of the galls we therefore conclude that the 1991 sample was erroneously determined as P. ligustrifoliae and is in fact C. zehntneri .
