Key to species of the European Scorpioteleia

1 Petiole at least four times as long as wide ( Fig. 1 ); gastral segment 1 in females compressed posteriorly, with remaining tergites at least partly exposed at rest; antennae slender with preapical flagellomeres at least 2.5 times as long as wide (Fig. 6). S. longepetiolata group ........................................................................................................................... 2

– Petiole short, at most 2.5 times as long as wide ( Fig. 3 ); gastral segment 1 in females abruptly narrowed posteriorly; remaining segments tubular and completely concealed within segment 1 but forming a scorpion-tail-like structure when extruded; antennae with preapical flagellomeres at most twice as long as wide (Fig. 8). S. compressa group ........................................................................................................................... 3

2(1) Mesosoma slender ( Fig. 2 ); subapical flagellomere in females at least three times as long as wide (Fig. 7); F 1 in males very deeply emarginated and strongly convex dorsally ( Fig. 12 ) ....................................................................................................... S. nixoni sp. nov.

– Mesosoma stouter ( Fig 1 ); subapical flagellomere in females at most 2.5 times as long as wide (Fig. 6); F 1 in males hardly convex dorsally (Fig. 11) ........................................... ............................................................................... S. longepetiolata ( Thomson, 1859) .

3(1) Macrotergite with fine striation at base between slightly indicated middle furrow and short lateral impressions; pronotal shoulders sharply pointed ( Fig. 5 ). .......................... ................................................................................................... S. cebes ( Nixon, 1957) .

– Macrotergite smooth at base between medial furrow and lateral impressions; pronotal shoulders angular, not pointed. .................................................................................... 4

4(2) Body large and stout (5-6 mm) ( Fig. 4 ); antennae of females with even, dense, contiguous pubescence; hairs shorter than half of the width of flagellomeres ( Fig. 10 ); radial cell large, triangular, with stigmal vein slightly oblique ( Fig. 20 ); lateral impressions at base of macrotergite large and deep; apical part of macrosternite bare in females; F 1 in males with basal emargination symmetrical, covering less than half of the flagellomere ( Fig. 15 ) ........................................................................................ S. luteipes (Kieffer, 1910) .

– Body smaller and slender (3-4.5 mm) ( Fig. 3 ); antennae of females with short, semidecumbent pubescence interspersed with single long erect hairs (Fig. 8); radial cell narrow with strongly oblique stigmal vein ( Fig. 18 ); lateral impressions at base of macrotergite inconspicuous; all surface of macrosternite pubescent in females; F 1 in males with basal emargination asymmetrical, covering more than half of the flagellomere ( Fig. 13 ). ..... ......................................................................................... S. compressa (Kieffer, 1910) .
