Cerroneuroterus monzeni (Dettmer, 1934)

Neuroterus monzeni Dettmer, 1934: 128, ♀ [♂ ♀ in Monzen (1954: 31)].

Cerroneuroterus monzeni (Dettmer) Melika et al. (2010: 23), ♂ ♀ & ǒ.

Distribution. China (Zhejiang Province) (Ju et al. 2022: in press), Japan (Honshu) (Dettmer 1934: 129; Sakagami 1952: 73; Monzen 1954: 32), and Korean Peninsula (Pujade-Villar et al. 2020a: 1213).

Remarks. Sexual females were described by Dettmer (1934). Later, Monzen redescribed the sexual generation, including the males (Monzen 1954). The asexual generation was described based only on the galls (Yukawa & Masuda 1996). The sexual (C-101) and the asexual (C-092) generations were linked experimentally by Yukawa & Masuda (1996).

Biology. The catkin galls of the sexual generation and the detachable leaf galls of the asexual generation both develop on Q. acutissima and Q. variabilis (sect. Cerris) (Table 1; Monzen 1954; Melika et al. 2010).
