Aphelomyx [sic] crispulae Mukaigawa, 1920 Incertae sedis

Aphelomyx [sic] crispulae Mukaigawa, 1920a: 21 , ♂ ♀.

Distribution. Japan (Honshu) ( Mukaigawa 1920a: 21; 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. crispulae are Synergus inquilines rather than Cynipini gall inducers. However, the descriptions are not detailed enough to reach a final conclusion.

Biology. Mukaigawa (1920a) described adults of the sexual generation (probably inquilines, see Remarks 2 above) and their galls on Q. mongolica ssp. crispula (= Q. crispula ) (sect. Quercus ). According to Yukawa & Masuda (1996), the galls correspond to the asexual generation of Andricus hakonensis .
