From Mackay and Mackay (2010): The specimens from Perú were collected in the “ant plant” Cecropia tesmmannii [Cecropiaceae]. They are reported to nest in an undescribed species of Cecropia in Perú (Davidson et al., 1989), where workers of the ant Camponotus balzani pursue and attack alate females. Neoponera luteola workers will attack and kill encroaching vines, if the vines have workers of the ant genus Crematogaster (Davidson et al., 1989). Dealate females were collected loose in September (Perú).
From Mackay and Mackay (2010): The shape of the petiole of N. luteola (thickened as viewed from the side and narrowed anteriorly as in Neoponera crenata as viewed from above) together with the presence of at least a partial malar carina and the form of the subpetiolar process would place N. luteola in the crenata complex. It is easily separated from all of the others in the complex, as the malar carina is only partially formed in the worker (completely formed in the female) and the pronotal margin is weakly developed. The relatively widely separated frontal carinae in the worker and female of N. luteola would separate it from most of the other species of Pachycondyla. The workers are ferrugineous red and the females are a dark chestnut brown, rare colors in Pachycondyla.
Mann (1916) considered R. luteola to be near Neoponera cavinodis. Actually they are very different and would not be confused (see R. cavinodis discussion).

This ant occurs in rainforest, riparian forest and tropical wet forest from 200 - 750 meters elevation. (Mackay and Mackay 2010)
Colonies nest in the hollow stems of live Cecropia trees (Davidson & Fisher 1991). A single polygynous colony can be the exclusive inhabitant of one Cecropia tree 30-35m high, with several tens of thousands of workers (Verhaagh 1994).
Relative to other Ponerinae, queen-worker dimorphism is very pronounced

From Mackay and Mackay (2010): The worker is a moderate sized (total length 8 millimeters) ferrugineous red ant. The mandibles have approximately 15 small teeth. The anterior border of the clypeus is broadly convex, the medial lobe is present but poorly developed. The head length is 1.8 mm; the head width 1.5 mm. The malar carina is poorly developed and only evident in about the first ⅓ of its length and does not extend to the eye. The eye is relatively small (maximum diameter 0.37 mm, located slightly more than one diameter from the anterior margin of the head. The scape is relatively short (total length 1.6 mm) and extends slightly past the posterior lateral corner of the head. The sides of the head are weakly convex, the posterior margin is concave. The pronotal shoulder is swollen and barely forms a carina. The mesosoma is depressed at the metanotal suture, but the sculpture is barely interrupted. The propodeal spiracle is slit-shaped. The petiole is thick when viewed in profile with the subpetiolar process well developed, consisting of a blunt ventrally projecting lobe anteriorly followed by a concave region and a broad posterior swollen region. The petiole is narrowed anteriorly when viewed from above, similar in shape to that of N. crenata.
Erect hairs are mostly long (0.6 mm) and abundant on the mandibles, clypeus, dorsal and ventral surfaces of head, scape, mesosoma, petiole and all surfaces of the gaster, the hairs on the legs are similar, but are mostly suberect. Appressed yellow or golden pubescence is abundant on all surfaces. The metasternal process consists of a pair of long slender lobes, unlike those of any other species in the New World.
Most surfaces are moderately to strongly shining and weakly coriaceous.
From Mackay and Mackay (2010): The female (undescribed) is a medium-sized (total length 12 mm) chestnut brown specimen. The head length is 2.3 mm; the head width is 2.15 mm. There are about ten mandibular teeth, most are poorly developed. The anterior border of the clypeus is weakly convex; the head is narrowed anteriorly and the posterior margin is concave. The malar carina is present and extends to the anterior border of the eye; the maximum eye diameter is 0.68 mm. The scape (1.98 mm) extends only slightly past the posterior lateral corner of the head. The pronotal shoulder is swollen but does not form a margin or carina; the propodeal spiracle is slit-shaped. The petiole is thick when viewed in profile; the subpetiolar process has an anterior lobe and a gradually diminishing posterior portion.
Erect hairs are abundant on nearly all surfaces, including the mandibles, clypeus, dorsal and ventral surfaces of the head, posterior margin, sides of the head, scapes, mesosoma, petiole, gaster, the hairs on the legs are mostly suberect, but are abundant and are about as long as the width of the leg. Appressed golden pubescence is present on the head, dorsum and side of the mesosoma, dorsum and side of the petiole and all surfaces of the gaster.
The mandibles are very finely striate and shining, the dorsum of the head is finely punctate and dull, as is the dorsum of the mesosoma and the side of the mesosoma is mostly finely punctate and moderately shining, the side of the petiole is punctate and weakly shining, the posterior face is polished and shining, the gaster is punctate and moderately shining.
Males are not known for this species.

This species gets its name from the Latin word luteolus, meaning yellowish, referring to the color of the worker. (Mackay and Mackay 2010)
