gall surface are usually on the top of the gall, forming a crown around the top of the gall and thus the gall appears slightly elongated and not rounded (Figs 41-46), the galls when mature turn slightly brown, however, the grayish green colouration al­ways present and the surface does not shrink; the texture of the gall surface more closely resembles that of Andricus lignicolus (HARTIG, 1840) than A. infectorius. In A infectorius the protuberances are located all over the surface of the gall and never form a kind of crown on the top, the gall is rounded (Figs 76-78); when ma­ture, the galls turn dark to reddish brown, totally lose their greenish colour and shrink when they fall from the tree. The galls of A. sternlichti are much larger, light brown when mature, do not shrink and the protuberances on the gall surface are more delicate, never forming a crown on the top; the gall parenchima is much lighter, and after maturation of the gall is not as hard as in A moreae and A. infectorius. Galls of A. infectorius fall extremely easily when mature, while neither the galls of A. sternlichti or A. moreae are dehiscent. Figs 60-62.
