Explanation of Names
Oncocephalus geniculatus (Stål 1872)
geniculatus - 'with accentuated knees' (refers to the coloration)
~14-15 mm
The dark patches inside the cells of the hemelytra and the presence of a lateral tubercle anterior to the transverse constriction of the pronotum separate this species from O. nubilus and O. variabilis. It is difficult to separate this species from O. apiculatus, a rarely collected species from the central United States; the ratios of the antennal segments is the feature currently used.
