Callirhytis kunugicola Shinji, 1943 Incertae sedis

Callirhytis kunugico la Shinji, 1943a: 95, ♂ ♀.

Callirhytis kunugico la Shinji, 1944: 441, ♂ ♀ syn. nov. [see Remarks 2 below].

Distribution. Japan (Honshu) (Shinji 1943a: 95; Shinji 1944: 68 (photo 116) and 411; Sakagami 1952: 74)

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 Callirhytis or any other genus.

Remarks (2). Callirhytis kunugicola was described as a new species in Shinji (1943a) and this description was later duplicated in Shinji (1944). Thus, Callirhytis kunugicola Shinji, 1943 (= C. kunugicola Shinji, 1944 syn. nov.).

Biology. Based on a photo in Yukawa & Masuda (1996) (C-083), the gall looks more like one induced by a dipteran gall midge than by a gall wasp (Pénzes et al. 2018). Found on Q. acutissima (sect. Cerris) (Sakagami 1952).
