Pteronidea pavida var. notanda Enslin, 1916a: 423. Lectotype designated below. Synonymy by Lacourt (1999). Diagnosis Closest to E. papillosa, see differences discussed under that species. Type material examined Lectotype Nematus cylindricus, here designated GERMANY • ♀; northern Germany [according to Hartig 1840: 22]; ZSM, GBIF-GISHym3248. Notes Most paralectotypes are also E. pavida, but apparently include also E. gracilidentata (GBIFGISHym3249, 3250, and maybe 3256) and E. similator (GBIF-GISHym3255). Lectotype Pteronidea pavida var. notanda, here designated FRANCE – Basse-Normandie • ♀; Lisieux; A. Loiselle leg.; ZSM, GBIF-GISHym3364. Host plants A wide spectrum of species of Salix, but S. caprea is a preferred host; occasionally on Populus tremula, whereas mentions of Alnus spp. are probably the result of misidentification (Pschorn-Walcher & Altenhofer 2000). Genetics COI Based on 12 specimens, maximum within-species distance is 0.61% and the nearest neighbour, diverging by a minimum of 2.74%, is Euura papillosa. Nuclear Based on 4 specimens, maximum within-species distance is 0.15% (0.03% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.62%, is Euura papillosa. Distribution and material examined Palaearctic. Specimens studied are from Austria, Belgium, Bulgaria, Finland, France, Germany, Norway, and Sweden.
