Pteronidea semiopaca Lindqvist, 1958: 97 .

Pachynematus tenuiserra Lindqvist, 1949: 80–81 . Secondary homonym of Amauronematus tenuiserra Lindqvist, 1944 [= Euura tenuiserra (Lindqvist, 1944) ]. Syn. nov.

Euura scandica Vårdal & Heibo, 2014 in Prous et al. 2014: 53. Replacement name for Pachynematus tenuiserra Lindqvist, 1949 .

Diagnosis

Most similar to E. platystigma and E. dissimilis : see discussion under those species.

Type material examined

Holotype Pteronidea semiopaca

FINLAND – Inari Lapland • ♀; Utsjoki, Outakoski; 69.61° N, 25.98° E; 25 Jun. 1947; E. Lindqvist leg.; MZH, http://id.luomus.fi/GL.3519.

Notes

Mesepisternum of holotype very slightly matt; pronotum colouration darker than in E. platystigma ; claws with rather large subapical tooth. A paratype (http://id.luomus.fi/ GL.3518) seems to be E. sagmarius .

Holotype Pachynematus tenuiserra

FINLAND – Lapin Lääni • ♀; Saana ; 69.05° N, 20.85° E; A. Nordman leg.; MZH, http://id.luomus.fi/ GL.3594.

Host plants

Astragalus frigidus (L.) A.Gray.
