Asterococcus quercicola Borchsenius

Asterococcus quercicola Borchsenius 1960: 124 –128

Type details. CHINA, Yunnan Province, Mutszian, on Fagaceae , 3.iii.1955, Liao Den-si. Depository: ZIAS: paratype adf—all other type specimens were deposited in China, including the holotype (I. Gavilov, pers. comm.). However, the whereabouts of Borchsenius’ material in China is uncertain. None of his slides are present in the Zoological Museum, Chinese Academy of Sciences, where they are thought to have been deposited. Borchseniuus worked with Prof.Wang Zi-qing. When Wang Zi-qing died in 1999, his collection was found to have not been deposited in the Zoological Museum. The whereabouts of this collection is currently uncertain and may have been lost (San-an Wu, pers. comm.).

Material studied. CHINA, Yunnan, Miokiang, on Quercus sp. ( Fagaceae ), 30.iii.1950, Lao Din-si (BMNH): 6/9adff (g).
