This photo is of an undescribed Columbiana from Columbia 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. Unlike Columbisoga, the lateral carinae of the pronotum curve laterally and do not reach the hind margin of the pronotum.
