From Wheeler, W. M. 1921), This species is found with Tachigalia but in the ground and not in petioles. In addition, it can often be found with Coccidotrophus and Eunausibius and destroys the colonies of these organisms. Additionally, this species can be found in ridge forest litter in Costa Rica and was collected at an elevation of 110m in Colombia. It was foraging on the vegetation in Venezuela.
Pacheco and Mackay (2013) – Worker - This species is bicolored with a golden yellow body and a dark brown gaster. The eye is relatively large with 10-12 ommatidia The anterior border of the clypeus is lacking teeth. This species can• be easily recognized by the shape of the petiole. The petiole (side view) is approximately as wide as tall with the anterior edge rounded and lower than the posterior edge.
This species may be confused with Solenopsis bicolor (which overlaps in distribution) based on the anterior clypeal margin and bicolored coloration. However, it can be separated as the petiolar node is unique to this species and thus dissimilar in shape to that of C. bicolor where the petiole is narrow in side view. Additionally, C. bicolor has long erect hairs on all body surfaces and often 0.240 mm in total length on the mesosoma, as compared to the much shorter (0.100 mm) setae present on S. altinodis.
