induced by an animal (galls are such), are valid and have priority. Thus Andricus gallaeviscosus (Fairmaire) will be the correct name of the species and is a comb. nov. Rejtő (1887) described a new variety of Andricus glutinosus (Giraud), which he named Cynips glutinosa Gir. var. dentimitrata. Bálás (1941) erected this to the status of an independent species, Cynips dentimitrata (Rejtő) and later Ambrus (1974) listed the species as Andricus dentimitratus Rejtő. Cynips glutinosa Gir. var. dentimitrata Rejtő, 1887 is identical with Andricus gallaeviscosus and, thus, is a syn. nov. This species was long thought to possess only a unisexual generation in its lifecycle (e.g. Ambrus 1974). The gall of the unisexual generation develops at the base of the acorn cup and may cover the stunted acorn. The gall is divided into two parts - an upper, cap-like structure consisting of radiating and pointed projections, and a lower, more globular part. 15 x 30 mm. Initially green, becoming bright reddish brown when mature. The outer surface of the gall is covered in an extremely sticky coating. The larval chamber is located within a small airspace in the lower part of the gall, and is monocular and thin-walled. The gall of the unisexual generation matures and falls in September. Adults emerge in November - December, with part of population emerging in the following spring. The unisexual generation is found on Q. pubescens, Q. petraea, and Q. robur (Ambrus 1974, Csóka 1997). The bisexual generation of this species has only recently been identified (Pujade 1994), having long been known by another name - Andricus jloridus Tavares, 1918. Pujade (1994) observed a female A. jloridus to oviposit in a bud, leading to the development of the unisexual gall of Andricus gallaeviscosus. Thus Andricus jloridus is a syn. nov. to A. gallaeviscosus. Galls of the bisexual generation are small, thin-walled structures which develop in the female flowers of the same species of oaks attacked by the unisexual form. We have not yet found the bisexual generation in Hungary. Andricus gallaeviscosus is a south European species, recorded from France, Spain (Dalla Torre and Kieffer 1910), Andorra (Pujade 1994), Italy, Austria, the Czech Republic (Valtice, South Moravia: Stone, personal communication), Hungary (only known from two locations in the areas surrounding Sopron and Kőszeg), Yugoslavia (Baudys 1928), and Bulgaria (Stara Mountains: Stone, personal communication). Common and often abundant in the Mediterranean region but rather sporadic and rare in Central and Western Europe. In some years the unisexual generation gall is very common in the Kőszeg Mountains on Q. petraea. Acknowledgments - We express our deepest appreciation to G. N.
