Abstract: 109 Euura declinata (Förster, 1854) Figs 115, 366, 367 Nematus declinatus Förster, 1854a: 348–349. Lectotype designated by Haris (1997). Pteronus capito Konow, 1903b: 307 (key). Lectotype designated by Enslin (1916a). Diagnosis Mostly black, pterostigma pale, claws with a large subapical tooth clearly separated from apical one, or bifid, mesepisternum smooth, valvula 3 elongate, thin and gradually tapering. The most similar species is E. scotonota (character states in parentheses), from which it differs possibly by mostly black sterna (pale). Closely related is also E. excisa (claws with small subapical tooth, mesepisternum matt). Type material examined Lectotype Nematus declinatus GERMANY – Nordrhein-Westfalen • ♂; Aachen area; 50.77° N, 6.09° E; A. Förster leg.; ZSM, GBIFGISHym3260. Lectotype Pteronus capito GERMANY – Sachsen • ♀; SDEI, GBIF-GISHym3878. Notes The synonymy of Pteronus capito with Nematus declinatus Förster by Taeger & Blank (1998) is here accepted. The projection of tergite 8 of the type specimen of declinatus does not fit Euura clitellata or E. fallax (which was considered within the range of variability of Pachynematus fallax by Liston & Burger, 2009). Genitalia of the type specimen are unfortunately lost (Liston & Burger 2009), but the drawing by Conde (who studied the type specimen) in an unpublished manuscript on Nematinae fits best with the specimen DEI-GISHym17598 (Figs 366–367) that we consider to be conspecific with females described by Konow as Pteronus capito. The penis valve is similar to that of the closely related E. scotonota. Host plants Unknown. Genetics COI Based on 2 specimens, maximum within-species distance is 0.16% and the nearest neighbour, diverging by a minimum of 1.29%, is Euura scotonota. Nuclear Only one sequence available, a female with haplotypes diverging by 0%. The nearest neighbour, diverging by a minimum of 0.89%, is Euura excisa. Distribution and material examined Palaearctic. Specimens studied are from Czech Republic, France, and Germany.
