Key to subgenera of Eupyrgota

1. Large, robust species: wing length (7–) 9–21 mm; scutellum with 3–6 pairs of sctl setae, if rarely with 2 pairs, then fore trochanter of female with spiny setulae, ventral hooks of the oviscape (if present), wide and strong, and wing widely yellow or grey, usually with apex dark grey or brown. .......................................... 2.

— Slender and smaller species: wing length 5–8 (–9) mm; scutellum with one pair of sctl setae, if with 2 pairs, then fore trochanter of female without spiny setulae, ventral hooks of oviscape sharp and slender. ............. ................................................................................................................................................................ Taeniomastix

2. Oviscape uniformly sclerotized, with 2 robust ventral hooks anterior of apex. Body size and coloration variable. ........................................................................................................................................... Eupyrgota s. str.

— Oviscape with V-shaped pale desclerotized area on its ventral side, separating its apical portion from basal; ventroapical area anterior of terminal opening with a narrow bordered, sucker-like slit, but without ventral hooks. Body size and coloration variable. .......................................................................................... Asipyrgota .
