Cynips folii form taschenbergi Kinsey, 1920, Bull. Amer. Mus. Nat. 
Hist. 42: 379. 
FEMALE AND MALE. — Said to differ in no respect from C. folii 
flosculi form flosculi. Differing from C. longiventris longiventris form 
substituta in having the legs including the femora a brighter, clearer 
yellow; differing from C. divisa divisa form verrucosa in having the 
mesonotum and mesopleura entirely smooth and shining (figs. 77, 78, 
82, 89, 90, 92, 99, 113). 
GALL. — Very similar to that of C. folii flosculi form flosculi and 
C. longiventris similis; bearing shorter hairs (which, however, form a 
solid, puberulent covering for the gall), being at first red and then 
rich violet-purple and finally blackened in color; on the young stems, 
or (more often) on the large stems or the main trunk, on Quercus 
pedunculata and Q. ses&iliflora; probably also on Q. pubescens. Figures 
107-112, 121, 127-128. 
RANGE. — Probably the same as that of the agamic form of the 
variety folii ( q.v .), which ranges thruout more Central Europe (fig. 15).
