Economic Importance



This photo is of an undescribed Columbiana from Colombia that I took for Bartlett (2010).  Tropidocephalini lack teeth on the calcar and all the New World taxa have strongly asymmetrical genitalia. The Columbiana I have seen tend to be uniformly colored species, and both of the described species have ventral processes on the opening of the pygofer, which I understand to be a genus-level feature. Unlike Columbisoga, the lateral carinae of the pronotum curve laterally and do not reach the hind margin of the pronotum.
