Material examined. 1♀ ( Figs 8A, B , 9A ), Austria, “Piesting.”, “Wand 10/S 866”. For more material, see Hara and Shinohara (2015) .

Remarks. The ovipositors of G. abieticola , G. albiclavata Hara, 2015 , G. hokkaidoensis Hara & Shinohara, 2015 and G. kojimai Hara & Shinohara, 2015 , were described in detail by Hara & Shinohara (2015), who proposed the G. abieticola group for these four species as a part of the G. socia group. The ovipositors of these four species ( Figs 8A, B , 9A ; fig. 5 in Hara & Nakamura 2015; figs 7C–O, 8A–L in Hara & Shinohara 2015) are very similar to the ovipositors of G. hercyniae (Hartig, 1837) and G. polytoma (Hartig, 1834) ( Figs 8K, L , 9I, J ; figs 1–3, 30– 44 in Reeks 1941) of the G. polytoma group. Their ovipositors are characterized by the large and stout posterior projection on the processus articularis of lance ( Figs 8A, B, K, L ). This feature appears to be unique to these six species and may suggest the close relationship of G. abieticola and similar species with the G. polytoma group (the lances of other members of the group have been neither described nor figured). The following features are also common to these six species: lance dorsally without median furrow, with posterior projection on processus articularis apically extending beyond most basal annular suture of lance, rather expanded ventrally beyond main body of lance in lateral view and apical cleft short; lancet with sclerotized band of radix sharply bent and wider than olistheter at twisted part (arrowed parts in Figs 9A, I, J ); first ctenidium widely separated from ventral margin of lancet; serrula of second annulus not larger than serrula of third annulus.
