on Quercus, sexual generation

Swelling of the petiole or, less often, the midrib. The gall is unilocular, but often several galls are fused. Without breeding the gall cannot be distinguished from the one by sieboldi.

hostplants

Fagaceae, monophagous

Quercus cerris, lusitanica, petraea, pubescens, pyrenaica, robur, suber.

synonyms

Until after 1990 it was generally assumed the the agamous generation of A. sieboldi and the sexual generation of A. testaceipes belonged to a single species that sometimes was called (as by Roskam), more often sieboldi (e.g. Redfern & Shirley). Experimentally this was shown to be incorrect, two independent species are involved. As yet, the agamous generation of testaceipes is unknown, although there is a suspicion that it might be A. rhyzomae.

parasitoids, predators

Eurytoma brunniventris; Torymus nobilis.
