Figs 197 , 425

Nematus miltonotus Zaddach, 1883 in Brischke 1883: 135, 143. Syntypes ♀♀, probably destroyed ( Blank & Taeger 1998).Type localities: Poland, Gdansk [Danzig]; Russia, Kaliningrad [Königsberg]; Germany, Mecklenburg.

Amauronematus jaroslawensis Jakowlew, 1891: 25 . Holotype ♀ (DEI-GISHym30176, ZIN). Type locality: Russia, Yaroslavl oblast, Yaroslavskiy Rayon. Synonymy by Enslin (1915).

Amauronematus hercyniae Konow, 1896: 163 . Syntypes ♀ ♂, no specimens located. Type localities: Germany and Russia. Synonymy by Enslin (1915).

Diagnosis

Females are almost completely yellowish (abdomen can be green while alive). Females of E. sagmarius can be almost as pale, but they are more reddish or brownish in colour and abdomen is still mostly black dorsally (possibly always mostly pale in E. miltonota ). Because they use different willow hosts, with different habitat requirements, it is also unlikely that these species occur in the same localities. Its extensively pale head around eyes and abdomen ventrally pale should enable separation of E. miltonota males from the others in the group (mostly black).

Type material examined

Holotype Amauronematus jaroslawensis

RUSSIA – Yaroslavl oblast • ♀; Yaroslavskiy Rayon ; ZIN, DEI-GISHym30176 .

Genetics

COI

Based on 5 specimens, maximum within-species distance is 1.82% and the nearest neighbours, diverging by a minimum of 1.06%, are Euura nimbus and E. sagmarius .

Nuclear

Based on 4 specimens, maximum within-species distance is 1.05% (0.25% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.95%, is Euura nimbus .

Distribution and material examined

Palaearctic. Specimens studied are from Czech Republic, Germany, Russia, and Slovakia.
