Eriosomatinae — Fordini

Formosaphis micheliae Takahashi (1925)

Two HK samples from Michelia alba and one sample from Magnolia grandiflora are in BMNH. Also reported from HK by Lee & Winney (1981).

Geoica lucifuga (Zehntner, 1897)

Reported from HK by Tao (1999a) but no known vouchers. No HK material in BMNH. This species colonises grass roots, notably rice ( Oryza ) and sugar cane ( Saccharum ) and is common across warmer parts of Asia and the Indian Region. It is extremely likely to occur in HK.

Schlechtendalia chinensis (Bell, 1851)

The data for the sole HK voucher sample in BMNH are “Chinese gall on Rhus semialata [not in the HK Herbarium check list but listed as a synonym of R. chinensis elsewhere], imported from HK in m.v. [merchant vessel] ‘Elpenor’ ”. There are also two samples from mainland China in BMNH, one of them the lectotype / paralectotype series from the 19 th century with minimal data, and the other from 1975. One slide, in Laing’s handwriting, has the intriguing note: “? China. Makes a large gall which is imported at the London docks for extraction of gallic acid—A. W. Richardson”.
