Andricus henryi Pujade-Villar, Wang & Guo, 2018

Andricus henryi Pujade-Villar, Wang & Guo in Pujade-Villar et al. (2018b: 133), ♀.

Distribution. China (Anhui, Zhejiang Provinces) (Pujade-Villar et al. 2018b: 137).

Remarks. Bernardo et al. (2013) described an oak cynipid inquiline, Synergus castaneus Pujade-Villar, Bernardo & Viggiani, 2013, from Anhui Province, which was suspected to be a gall-inducer. Some years later, the true gall-inducer of the gall, A. henryi, was described from Zhejiang (Pujade-Villar et al. 2018b).

Biology. Only females, probably of the sexual generation, have been described. Andricus henryi induces integral twig galls on Castanea (Table 1; Pujade-Villar et al. 2018b). This is the only Andricus species globally known to gall Castanea .
