Key to species of Neohydnocera ( Clerinae : Hydnocerini ) in eastern North America

1. Body mostly or entirely testaceus (A)............................................ Neohydnocera aegra (Newman)

1’. Body with black markings (often largely dark brown to black; B)............................................... 2

2 (1’). Elytra short, just over half the length of the abdomen, usually exposing 3+ abdominal segments (abdomens sometimes curl downwards, and if so, so a lateral view is necessary to compare abdominal and elytral lengths; A), elytra in dorsal view with lateral margin straight for about 2/3 of their length, then bending towards the tip or slightly concave on apical 1/3 (B).............................................................................. Neohydnocera longicollis (Ziegler)

2’. Elytra longer, exposing no more than 2 abdominal segments (C), in dorsal view, lateral margin straight for almost their entire length before smoothly curving towards tip very close to apex (D).................... Neohydnocera tabida (LeConte)
