Comments. The workers of this species are distinguished from other similar taxa by showing a pair of spines on the propodeum and a long medial spine on the petiole; the propodeum is convex anteriorly and concave posteriorly; the metanotal groove is strongly depressed. The biology and behavior of C. santschii is unknown. The examined specimens were collected through pitfall traps and by hand in a seasonal dry forest in western Ecuador. It was formerly known from Central America and northern Colombia (Magdalena) ( Mackay and Mackay, 2019). This is the southernmost record of this species in the continent.
