KEY TO GENERA Of PRONOTOCREPINI

1. Lateral margins of pronotum explanate for entire length (fig. 7); second antennal segment strongly inflated (fig. 7); embolium slightly explanate, usually paler than corium; first rostral segment overlapping proximal margin of gula (fig. 8A); females never brachypterous................................... Pronotocrepis Knight

– Lateral margin of pronotum not explanate; second antennal segment sometimes inflated distally (figs. 3, 7); embolium not explanate; first rostral segment not overlapping proximal margin of gula (figs. 4A, 10A); females submacropterous to strongly brachypterous; Nearctic................................................. 2

2. Head nearly vertical (fig. 1); second antennal segment at most weakly inflated distally (fig. 1); females submacropterous; Palearctic................. Ethelastia Reuter

– Head horizontal to oblique; second antennal segment strongly inflated distally; females either macropterous or strongly brachypterous............................. 3

3. Head oblique (fig. 4A); second antennal segments inflated distally (fig. 3); calli distinct; corium usually not completely black (fig. 3), with dense dull or shiny vestiture; males macropterous (fig. 3); females brachypterous with hemelytra upturned apically (fig. 3); females with second and third abdominal segments strongly petiolate, constricted (fig. 3); Nearctic..................... Orectoderus Uhler

– Head elongate and horizontal (figs. 7, 10A); second antennal segment inflated distally (fig. 7); corium completely black and very shiny; calli not distinct (fig. 7); vestiture of corium not dense (fig. 10D); males and females macropterous (fig. 7); Nearctic........................................................
