Distribution. China (Liaoning, Shaanxi Province) ( Abe 1986: 442), Japan (Hokkaido, Honshu) ( Monzen 1929: 351; Monzen 1954: 26; Shinji 1944: 47; Abe 1986: 442; Abe 2007: 478), Korean Peninsula ( Abe 1986: 442; PujadeVillar et al. 2020a: 1212), and the Russian Far East ( Kovalev 1965: 32; Abe 1986: 442).

Remarks. Abe (1986) considered this species a synonym of A. targionii Kieffer, 1903 , but later Abe (2007) confirmed its status as a distinct valid species based on cytological data and host plant associations. Therefore, all A. targionii collected on Q. dentata mentioned in Abe (1986) belong to A. pseudoflos , whereas all the A. targionii collected on Q. aliena belong to A. targionii .

Biology. Andricus pseudoflos is a purely parthenogenetic species derived from A. mukaigawae by loss of the sexual generation from an ancestral cyclically parthenogenetic lifecycle (Abe 2007; Wachi et al. 2012). It induces flower-like leaf galls on Q. dentata (sect. Quercus ) ( Table 1; Abe 2007).
