Euura tiliae Prous & Liston & Monckton & Kramp & Vårdal & Vikberg & Heibo & Mutanen 2025

331 Euura tiliae (Zinovjev, 1998) comb. nov. Nematus tiliae Zinovjev, 1998: 23–26. Diagnosis Could be confused with almost completely pale specimens of Euura miliaris or members of the E. bergmanni and E. oligospila groups. The rather short valvula 3 is most similar to E. jugicola, E. hypoxantha, and the E. papillosa group. The lancet is most similar to the E. papillosa group (overall shape, serrulae, and radix seems to be about as long as lamnium). Its darker pterostigma and not clearly bifid claws (somewhat similar to E. gregaria) distinguish E. tiliae from the species mentioned above. Without genetic data it is not clear to which Euura group E. tiliae could belong, but there seems to be little doubt that the species belongs to Euura rather than Nematus. Shinohara & Hara (2015) retained it in Nematus. We do not consider the small differences in claws to other Euura to be sufficient to exclude the species from this genus.
