Identification
Key to the species of Bradycinetulus (after Cartwright 1953)

1 Eye canthus nearly straight edged laterally, wide clypeal horn of male bisinuate apically, the external angles projecting forward, acute, and scarcely thicker than the adjacent edges, which converge posteriorly; median thoracic horns heavy, directed upward, their sharply rounded tips recurved posteriorly (North Carolina to Florida and Mississippi) ................................................................. B. ferrugineus (Palisot de Beauvois)
1’ Eye canthus notched or emarginated, not straight edged laterally ................. 2

2 Wide clypeal horn of male distinctly trinodose apically, the external angles not projecting beyond median point, lateral edges parallel; median thoracic horns heavy, projecting forward and outward, sharply rounded and very little recurved (Nebraska to Texas and Arkansas) .......................................................... B. fossatus (Haldeman)
2’ Apex of clypeal horn of male widely truncate, straight across, the external angles slightly nodose, lateral edges parallel over apical two fifths, then diverging to base; median thoracic horns slender, directed forward and upward, basally flattened in front and behind (south Texas) ............................................................... B. Rex Cartwright
