[ S. diembroma Dodge from Jamaica is excluded as it is known only from the female sex. For a pictorial guide to the species, see Pape & Carlberg (2004).]

1. Vein R1 setose in full length, i.e., beyond the knob at level of subcostal break. Postgo­ nal apodeme not elongated ........................ thyropteronthos Pape, Dechmann & Vonhof

— Vein R1 setose only proximal to the knob at level of subcostal break. Postgonal apo­ deme distinctly elongated.............................................................................................. 2

2. Abdominal tergite 5 reddish ............................................................. baumhoveri Dodge

— Abdominal tergite 5 black ............................................................................................. 3

3. Vesica with proximal part drawn out into a spiny process in addition to the usual vesical extension (see Dodge 1965 fig. 29) ................................................... paterna Dodge

— Vesica without separate spiny process in proximal part, only showing the vesical extension.......................................................................................................................4

4. Vesical extension with a small or large bifurcation....................................................... 5

— Vesical extension simple, entirely without bifurcation ................................................. 8

5. Vesical bifurcation small, mainly a subapical barb­ or thorn­like process (see fig. 24 in Mello­Patiu & Pape 2000) ............................................................. cuneata (Townsend)

— Cercus gradually tapering, tip pointed (Figs 3, 6)......................................................... 7

7. Proximal extension of vesica about the length of swollen part of distiphallus; vesical bifurcation with prongs of about equal length, the one perpendicular to longitudinal axis of vesical extension set close to base (Figs 1, 2) ................................ kuna sp. nov.

— Proximal extension of vesica much longer than swollen part of distiphallus; vesical bifurcation with prongs of subequal length, the one perpendicular to longitudinal axis of vesical extension is shortest and set just proximal to the mid point (Figs 4, 5) ......... ............................................................................................................... chiriqui sp. nov.
