Key to Hyphinoini genera

1. Pronotum distinctly elevated and swollen anteriorly, pronotal height usually>2x head length in frontal view............. 2

1’ Pronotum low to moderately elevated, not swollen, pronotal height not exceeding 1.5x head length in frontal view.........3

2’. In lateral view, metopidium vertical or curvilinear; in dorsal view, sides compressed into anterior angles or horns yielding a triangular appearance........................................................................ Hyphinoe Stål

2 (1). In lateral view, metopidium distinctly leaning forward; in dorsal view, sides tumid and enlarged, forming a semicircular platform....................................................................... Hanstruempelia Sakakibara

3. Suprahumeral horns robust and carinate, horn apex well above humeral angles; forewing membrane smoky to opaque, uniformly colored............................................................................................. 4

3’. If present, suprahumeral horns slender, acute, devoid of longitudinal carina, apex close to humeral angles; forewing membrane hyaline with narrow dark macula along main branch of R vein....................................... Tomogonia Stål

4 (3). Posterior pronotal process extending well beyond forewing apex; forewing densely and uniformly pubescent, lacking supernumerary veins.......................................................................... Eualthe Stål
