Seleucus cuneiformis Holmgren, 1860 Figs 6-14 View Figures 6–14
Material.
2 ♀ + 2 ♂ (RMNH) & 3 ♀ + 2 ♂ (AC), "Austria: Böhmerwald, Plöckenstein, 1200-1300 m, ex Blasticotoma filiceti on cf. Athyrium sp., coll[ected] 8.viii.2011, em[erged] 16 (1 ♂), 20 (1 ♀ + 1 ♂), 22 (1 ♂), 23 (2 ♀), 26 (1 ♀ + 1 ♂).vi.2012 & 1.vii.2012 (1 ♀), E. Altenhofer".
Biology.
Parasitoid of larvae of Blasticotoma filiceti Klug, 1834 ( Tenthredinoidea : Blasticotomidae ). The sex ratio is nearly balanced as far as the low numbers allow a conclusion. Only one male appeared before the females emerged; the others emerged together with the females.
Distribution.
Palaearctic China (Henan), Czech Republic; Finland; Germany; Japan (Hokkaido); Korea; Poland; NW European Russia; Far East Russia; Sweden ( Vikberg and Koponen 2000; Yu et al. 2012) and now Austria.
Notes.
The apex of the fore tibia has a more or less angulate lamella ( Fig. 8 View Figures 6–14 , not a tooth as is supposed to be present in Ctenopelmatinae ); the ovipositor sheath points upwards compared to the hypopygium ( Fig. 9 View Figures 6–14 ); the ovipositor has a dorsal notch (Vik berg and Koponen, 2000; which excludes it from the Phrudinae and corroborates its inclusion in the Ctenopelmatinae ); the first metasomal tergite has a long petiole and the spiracles are halfway along the notum ( Fig. 7 View Figures 6–14 ); the pterostigma is triangular with vein r emerging medially ( Fig. 6 View Figures 6–14 ); the frons is coarsely punctate ( Fig. 12 View Figures 6–14 ); the metasoma of the female is 3.0-3.5 times longer than the mesosoma ( Fig. 4 View Figures 4–5 ); below the clypeus is a distinct space because the clypeus is distinctly removed from the mandibles ( Figs 12, 13 View Figures 6–14 ); the clypeus has an apical fringe of bristles ( Fig. 13 View Figures 6–14 ); and the hind tarsus is very slender ( Fig. 14 View Figures 6–14 ).
