Andricus burgundus Giraud, 1859
Individual male flower buds are changed into 2 mm long, oval, yellow red, unilocular galls, generally 3-8 together. The wall is thin and hard, and the outside bears four faint longitudinal ridges.
Fagaceae, narrowly monophagous
Quercus cerris, suber.
A molecular and genetic analysis by Stone ao (2008a) has shown that burgundus actually is a morphospecies, a mix of the sexual generations of at least six species of which only the agamous generation was known: Andricus conglomeratus, coriarius, hystrix, pictus, polycerus and either crispator or multiplicatus.
