Comments:

J. Longino: In Costa Rica, this species occurs in wet to moist forested habitats in the lowlands of the Pacific slope. It is a relatively common species on the Osa Peninsula and vicinity, and I have one collection from the San Luis Valley just below Monteverde. Workers are relatively common nocturnal foragers, although I have seen them during the day tending Homoptera and at extrafloral nectaries. I have seen them as army ant prey. I have seen two nests, both in rotten branches near the ground. One was on the ground and one was suspended in low vegetation.

r. C. simillimus Sm.HNS

— Deux [[ worker ]] major et deux [[ worker ]] minor du Bresil que je dois a l'obligeance de M. Mayr me montrent que cette forme n'a avec le C. herculeanusHNS que des affinites apparentes provenant de la couleur. C'est une pure race du C. rubripesHNS, voisine du C. cognatusHNS par sa taille et sa couleur. La tete est mate et ponctuee; le thorax et l'abdomen sont finement reticules ponctues. La pubescence est fort longue, surtout sur l'abdomen, plus longue meme que chez le C. sexguttatusHNS. Sur les pattes elle est entierement appliquee. Le lobe du chaperon est fort developpe, echancre sur les cotes, et a bord anterieur concave; la carene est aussi tres marquee sur toute la longueur de l'epistome. Cette race est extremement rapprochee de la race C. indianusHNS Forel, dont elle a la forme et la sculpture; " mais chez ce dernier qui est entierement d'un noir brun, la pubescence est aussi faible que chez le C. sylvaticusHNS; les poils dresses sont aussi plus grossiers, moins abondants et d'un brun fonce (d'un blanc jaunatre chez le C. simillimusHNS); les pattes sont plus fortes et un peu plus aplaties.
