Hab. Panama, Volcan de Chiriqui (Champion). One example. 
In the shortness of the forehead and the markings of the elytra this species resembles 
the Neoclyti more than the Mecometopi, but the nearly smooth, convex thorax, and 
especially the short clavate antenne, in which the joints seven to eleven are consolidated 
into one with only faint traces of articulation, lead me to refer it to Mecometopus, in 
‘which genus alone a similar antennal structure is found.
