Nematus montanus Zaddach, 1883 in Brischke 1883: 142–143. Syntypes ♀ ♂, probably destroyed ( Blank & Taeger 1998). Type locality: Switzerland.

Nematus jemilleri Stein, 1894: 55–58 . Syntypes ♀ ♂ (BMNH?), not examined. Type locality: Germany, Bayern, and Czech Republic, Chodau. Synonymy by Konow (1904c).

Diagnosis

Mostly pale mesepisternum, black mesepimeron, and dorsally extensively black hind tibia and often hind femur usually enable separation of the species from the others in the group. The more or less straight basalmost suture of the lancet may distinguish the females from E. pallescens (basalmost suture distinctly inclined apically), but not from E. styx . The broad valvispina reliably distinguishes the males from the two other species (narrow valvispina). Abdomen and thorax dorsally from nearly completely black to mostly pale.

Host plants

Picea abies (L.) H.Karst. and probably at least some other species of Picea ( Enston & Williams 2024) . One generation per year.

Genetics

COI

Based on 6 specimens, maximum within-species distance is 0.78% and the nearest neighbour, diverging by a minimum of 0%, is Euura pallescens .

Nuclear

Based on 6 specimens, maximum within-species distance is 0.18% (0.12% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.64%, is Euura pallescens .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, France, Germany, and Slovakia.
