Ordo: Hymenoptera
Familia: Ichneumonidae
Genus: Seleucus
Name
Seleucus cuneiformis Holmgren, 1860 – Wikispecies link – Pensoft Profile
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[1]; Yu et al. 2012[2]) and now Austria.
Notes
The apex of the fore tibia has a more or less angulate lamella (Fig. 8, not a tooth as is supposed to be present in Ctenopelmatinae); the ovipositor sheath points upwards compared to the hypopygium (Fig. 9); the ovipositor has a dorsal notch (Vikberg 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); the pterostigma is triangular with vein r emerging medially (Fig. 6); the frons is coarsely punctate (Fig. 12); the metasoma of the female is 3.0–3.5 times longer than the mesosoma (Fig. 4); below the clypeus is a distinct space because the clypeus is distinctly removed from the mandibles (Figs 12, 13); the clypeus has an apical fringe of bristles (Fig. 13); and the hind tarsus is very slender (Fig. 14).
