Aphelomyx [sic] glanduliferae Mukaigawa, 1920 Incertae sedis

Aphelomyx [sic] glanduliferae Mukaigawa, 1920b: 131 , ♂ ♀.

Distribution. Japan (Honshu) ( Mukaigawa 1920b: 131; Mukaigawa 1922: 207; Shiraki 1952: 101).

Remarks. Uncertain status ( Abe et al. 2007; Pénzes et al. 2018). The types are lost and the original description does not allow confident identification to any Cynipini genus.

Remarks (2). Abe et al. (2007) concluded that the sexual adults of the species named A. glanduliferae are Synergus inquilines rather than Cynipini gall inducers. However, the descriptions are not detailed enough to reach a final conclusion.

Biology. Mukaigawa (1920b) demonstrated that this species has alternating generations based on field observations and described the sexual adults (probably inquilines, see Remarks 2 above) and galls of both generations (see galls on pictures C-127 and C- 143 in Yukawa & Masuda 1996): C-127 is a bud gall, while C-143 is a detachable round leaf gall, both on Q. serrata (sect. Quercus ).
