Remarks. See Remarks for A. pseudoflos. The distribution and host plant mentioned in the original description (Kieffer 1903) were erroneous and were corrected by Trotter (1903). Biology. Andricus targionii is a purely parthenogenetic species derived from A. kashiwaphilus by loss of the sexual generation from an ancestral cyclically parthenogenetic lifecycle (Abe 2007). It induces bur-shaped galls on Q. aliena and Q. mongolica (= Q. wutaishanica Mayr) (sect. Quercus) (Table 1; Abe 1986; Abe et al. 2007).
