Figs 194 View Figs 191–194 , 545 View Figs 534–545

Nematus fagi Zaddach, 1876 : Taf. II, 1. Holotype ♀, probably destroyed ( Blank & Taeger 1998). Type locality: Poland, Gdansk [Danzig], Jäschkenthale.

Diagnosis

Usually almost completely pale and very similar to E. miliaris . First metatarsomere is about 4 times as long as broad and darker in E. fagi (about 3 times as long as broad and paler in E. miliaris ). A male from Czech Republic (DEI-GISHym13853) is confirmed to be E. fagi based on COI. The male has a penis valve ( Fig. 545 View Figs 534–545 ) similar to E. viridis , but malar space is about as long as diameter of front ocellus, like in E. miliaris (the malar space is longer in E. viridis , at least usually).

Host plants

Fagus sylvatica L.

Genetics

COI

Based on 5 specimens, maximum within-species distance is 1.98% and the nearest neighbour, diverging by a minimum of 3.20%, is Euura miliaris .

Nuclear

Only one sequence available, a female with haplotypes diverging by 0%. The nearest neighbour, diverging by a minimum of 1.18%, is Euura miliaris .

Distribution and material examined

Palaearctic. Specimens studied are from Czech Republic, Finland, Germany, Slovenia, Sweden, Switzerland, and the United Kingdom.
