Euura anomaloptera group

= Tubpontania Vikberg, 2010

Diagnosis. Adult. In lateral view right mandible gradually tapering, left one with swollen base and thin, blade-like apex. Vein 2r-m normally present in both fore wings. Supraclypeal area densely setose. Antenna moderately long: ♀ about as long, or slightly longer, than costa of fore wing; ♂ longer than costa of fore wing. Cercus at most 4× as long as basal width and in dorsal view reaching back only to midpoint of valvula 3. Lancet: tapering rather strongly from base to apex; more or less curved, sometimes slightly sinuate. Sculpture on upper head more or less tuberculate. Penis valve ventrally without small spines; base of valvispina ventrally clearly divided from lobe on which it arises by an incision or at least a right-angled turn.

Larva. Third abdominal segment with 4 dorsal annulets; 1–3 with setae. Suranal plate with pseudocerci.

Gall. In leaves. A straight or spirally-twisted roll, sometimes many-layered. A procecidium is formed on upper leaf surface at the oviposition site.

Phenology. Most species univoltine, but at least E. purpureae and E. nitidinota often bivoltine ( Benander 1966, Stritt 1938, Vikberg 2010b).

Provisionally, the relatively well characterised morphological species are also readily identifiable by COI barcoding, but no data are yet available for E. nitidinota .
