Diagnosis

Externally most similar to E. connecta and E. leionota , but valvula 3 may usually be broader and almost square-shaped in E. mimus (narrowing towards the tip in E. connecta and E. leionota ). The lancet of E. mimus is most similar to E. connecta , but seems to be smaller (lamnium length 0.66–0.70 mm, n = 6) and broadening from tip to base less abruptly than in E. connecta (lamnium length 0.78–0.79 mm, n = 3). Males of E. leionota are not known for certain. The penis valve of E. mimus is most similar to E. leucopyga , E. connecta , E. parviserrata , E. polaris , and E. sulciceps , but may have a somewhat smaller valvispina and a smooth (uneven in the others) apical margin of paravalva below valvispina.

Unknown. A mention by Conde (1927) of a rearing from [cecidomyiid] galls on Salix may refer to a different species.

Genetics

COI

Based on 4 specimens, maximum within-species distance is 0.3% and the nearest neighbour, diverging by a minimum of 1.52%, is Euura leucopyga .

Nuclear

Based on 2 specimens, maximum within-species distance is 0% (0% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.78%, is Euura polaris .

Distribution and material examined

Palaearctic. Specimens studied are from Bulgaria, Finland, Germany, Norway, Russia, Sweden, and Switzerland.
