Key to species of Peltopsilopa

1. Ventral facial emargination very shallowly arched, almost flat (Fig. 7); facial ratio 0.50; dorsal facial seta well developed; scutellar base with a dentate, sharp, short projection laterally (Cuba).............................. P. schwarzi Cresson

- Ventral facial emargination conspicuously arched ( Figs. 1, 4 ); facial ratio 0.61‒0.63; dorsal facial seta more weakly developed; scutellar base lacking a dentate, sharp, short projection laterally (mainland Neotropics).............................. 2

2. Presurstylus in lateral view ( Fig. 31 ) elongate (length ca. 4.5X width), slender, parallel sided, apex shallowly rounded and drawn to a anteroventral point; postsurstylus in ventral view ( Fig. 39 ) with apex digitiform, not angulate................................................................................................. P. anisotomoides (Karsch)

- Presurstylus in lateral view ( Fig. 16 ) shorter and more robust (length no more than 3X width), pedunculated with posterior margin conspicuously emarginate, widened at base and apex; postsurstylus in ventral view ( Fig. 26 ) with apical portion angulate, with a short extension at 90°............................................................... P. acuta n.sp.
