Ceroptres quereicola [sic] (Shinji, 1938) Nomen dubium

Paraulax quereicola Shinji, 1938b: 203–204, ♀.

Ceroptres quereicola (Shinji) Liljeblad et al. (2008: 27–28) .

Distribution. Japan (Honshu) (Shinji 1938b: 204).

Remarks. Uncertain status (Abe et al. 2007; Lobato-Vila & Pujade-Villar 2019). The types are lost (Liljeblad et al. 2008) and the original description does not allow differentiation of this species from other Ceroptres (Liljeblad et al. 2008; Lobato-Vila & Pujade-Villar 2019).

Remarks (2). The combination Ceroptres quereicola (Shinji, 1938) first appeared in Liljeblad (2002). Abe et al. (2007) suggested that C. quereicola should be treated as an unplaced species within Ceroptres . Later, Liljeblad et al. (2008) formally transferred Paraulax quereicola to Ceroptres .

Biology. Shinji (1938b) observed C. quereicola ovipositing in swollen terminal branches of Quercus, thought to be Q. mongolica or Q. dentata (sect. Quercus). However, the host galls are unknown.
