Key to species of Barycnemis occurring in Japan (females)

1. Basal part of propodeum about as long as apical area ( Fig. 7 ). Hind basitarsus short, about 0.7× as long as tibia ( Fig. 6 ).......................................................................................... harpura (Schrank)

- Basal part of propodeum longer, about 1.5× as long as apical area ( Fig. 15 ). Hind leg with basitarsus 0.75–1.2× as long as tibia.................................................................................................... 2

2. Hind basitarsus 0.75–0.85× as long as tibia ( Fig. 19 ). Dorsolateral area of propodeum entirely evenly granulate. Ovipositor sheath 1.2× as long as first tergite............................................... .. naganoensis Khalaim , sp. nov.

- Hind basitarsus 1.0–1.2× as long as tibia. Dorsolateral area of propodeum centrally smooth or with weaker granulation than on periphery. Ovipositor sheath somewhat shorter than first tergite................................................ 3

3. Hind femur slender, about 4.0× as long as broad ( Fig. 3 ). Head, in lateral view, with antennae inserted near level of centre of head ( Fig. 1 ). First tergite with upper margin, in lateral view, more or less evenly arcuate, or sometimes with a weak angulation centrally.......................................................................... dissimilis (Gravenhorst)

- Hind femur robust, 2.8–3.0× as long as broad ( Fig. 4 ). Head, in lateral view, with antennae inserted distinctly below level of centre of head ( Fig. 2 ). First tergite with upper margin, in lateral view, with a strong angulation centrally ( Fig. 5 , arrow)............................................................................................. tobiasi Khalaim
