Key to known pupal cases of Nearctic species of Diogmites

1 Abdominal segments 3–7 with ventral transverse row of short bristle­like spines interrupted by 2 spaces, thereby forming 3 ventral groups of spines on each segment .............................. Diogmites discolor Loew

­ Abdominal segments 3–7 with uninterrupted ventral transverse row of bristle­like spines.........................2

2 Outer posterior antennal process elbowed basally; labral sheath with slight posterior callosity; abdominal segment 1 with dorsal transverse row of 27 spurs, median spurs not spatulate or bifurcate; abdominal segment 8 with 5 lateral bristle­like spines on each side; segment 9 rugose, ventral posterolateral processes not fused basally to dorsal posterolateral processes ................................ Diogmites misellus (Wiedemann)

­ Outer posterior antennal process straight; labral sheath lacking callosity; abdominal segment 1 with dorsal transverse row of 19 spurs, 5–7 spurs on each side of midline spatulate or wider apically, sometimes bifurcate or with short basal spine; abdominal segment 8 with 8–11 lateral bristle­like spines on each side; segment 9 not rugose, with ventral posterolateral processes fused basally to dorsal posterolateral processes ... .................................................................................................................
