A review species of the genus Ceroplastes (Hemiptera: Coccomorpha: Coccidae) in China Author Wu, San-An Author Wang, Xubo text Zootaxa 2019 2019-12-03 4701 6 520 536 journal article 24749 10.11646/zootaxa.4701.6.2 a0dcf616-a4ad-49d4-b35f-dd53a90c8ac7 1175-5326 3562574 FD1478CC-463B-4CB9-B3A2-20C0CD047149 Ceroplastes sinensis : a note on its distribution in China There are two contradictory views in the literature regarding the presence of Ceroplastes sinensis in China . Some authors have recorded it from China : Fernald (1903) , Wu (1935) , Chen & Wong (1936) and Li (1952) only listed “China’ for its distribution; Silvestri (1920) listed Shanghai and Hong Kong as distribution sites, based on Ehrhorn’s identification of specimens that Mr. A. Koebele collected; and Chou (1947) listed C . sinensis as one of 22 commonly seen scale insects on citrus in China , gave short descriptions of its morphology and biology, and said that “this species has a limited distribution, only found from Jiangsu , Guangdong and Sichuan ”. Pen (1960) studied its parasites in Szechwan (= Sichuan ) Province. On the other hand, Young (1959) and Yang 1982 ) considered that C. sinensis did not occur in China , and that the records of Wu (1935) and other publications were based on a misunderstanding from the scientific name “ sinensis ”. Xu (1964) agreed with Young (1959) based on review of publications by Fernald (1903) , Wu (1935) , Li (1952) and a probably erroneous reference, ‘Del Guercio. 1901. Science, n.s. xiii, no. 325, p.469’, which does not exist in the ScaleNet database. Qin et al. (1994) listed ‘ China ” as an incorrect distribution record, mainly because they considered Ehrhorn’s identification (see above), and the survey result by Silvestri (1929) , were “unlikely to be reliable”. We think that their conclusion that ‘ C. sinensis did not occur in China’ was not correct, since (1) Young (1959) and Yang 1982 ) and Xu (1964) did not provide any solid evidence; (2) Qin et al. (1994) ’s opinion on Ehrhorn’s identification was subjective; (3) although C. sinensis was not found in China by Silvestri (1929) , in the same paper he also said that many citrus-cultivating provinces such as Guangxi (=Kwangsi) and Sichuan (Szechouen) had not been investigated; and (4) Chou (1947) was not discussed in papers such as Yang (1982) and Qin et al. (1994) . Professor Io Chou was a student of Professor Silvestri, and spent two years in Italy in 1934–1935 so it is likely that he would have had knowledge of C. sinensis . As mentioned above, Chou gave distribution data in China , but unfortunately no illustration was given; so there is no sound evidence to support either the presence of C. sinensis in China , or its absence. No Chinese material of this species has been seen in this study.
