Treatment

217 Euura betulae ( Schmidt, 1997)

Fig. 235 View Figs 234–237. 234–235, 237

Amauronematus betulae Schmidt, 1997: 279–280 . Holotype ♀ (http://id.luomus.fi/GL.2501, MZH). Type locality: Finland, Juuma [735:60].

Diagnosis

The holotype is externally very similar to E. septentrionalis , but the lamnium is 1.5–1.6 times as long as the radix (holotype; DEI-GISHym80673) compared to 1.8–1.9 (based on Schmidt 1997) or 2.0–2.2 ( taiganus holotype, ZMUO.037302) in E. septentrionalis . We have associated only one other specimen (DEI-GISHym80673 from Primorsky Krai, Russia) with the holotype, based on the lancet and similar colouration. No males have been associated with the female.

Type material examined

Holotype Amauronematus betulae

FINLAND – Kuusamo • ♀; Juuma; 66.27° N, 29.38° E; 16 Jun. 1985; M. Ahola leg.; MZH, http://id.luomus.fi/GL.2501. GoogleMaps

Host plants

Since the holotype (collected on 16 Jun. 1985 by M. Ahola) is not a reared specimen, the host is not known for certain. Schmidt (1997: 280) mentioned that in his oviposition experiments a female or females (number of specimens not given) laid eggs on Betula nana and B. pubescens , but rejected willows. We have not examined any such specimens.

Genetics

COI

Only one sequence available. The nearest neighbours, diverging by a minimum of 0%, are Euura amicula , E. histrio , E. nuorbinjargi , E. rufa , E. septentrionalis , E. striata , and E. tenuis .

Nuclear

Only one sequence available, a female with haplotypes diverging by 0.7%. The nearest neighbour, diverging by a minimum of 0.07%, is Euura histrio .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Russia.
