Workers from French Guiana were collected in the plant Phyllodendron linnei.
From Mackay and Mackay (2010): The shape of the anterior face of the postpetiole distinguishes N. procidua from most of the others in the genus. Neoponera procidua can be separated from the common Pachycondyla harpax, in which the two faces of the postpetiole form an angle, by the presence of the metanotal suture on the dorsum of the mesosoma and by the pronotal carina, which overhangs the side of the pronotum, both of which are reduced or absent in workers of P. harpax. Rasopone cernua and Neoponera concava have concave anterior faces of the postpetiole, but both species have malar carinae, which are absent in N. procidua.

From Mackay and Mackay (2010): The worker is a relatively large (13 mm) dark reddish brown species. The mandibles have approximately nine teeth, the anterior border of the clypeus is broadly convex when viewed directly from above, it can be seen to be slightly depressed medially when viewed obliquely. The eye is small (maximum diameter 0.4 mm) and is located slightly more than 1 diameter from the anterior border of the head (side view). The malar carina is absent. The scape extends slightly past the posterior lateral corner of the head. The pronotal shoulder is formed into a sharp carina, which overhangs the side of the pronotum. The metanotal suture is slightly depressed below the level of the remainder of the mesosoma and definitely breaks the sculpture when seen from above. The propodeal spiracle is elongated. The propodeum is rounded along the posterior lateral edge. The anterior face of the petiole is nearly vertical and slightly concave and meets the broadly rounded posterior face near the anterior edge of the apex. The anterior face of the postpetiole (first segment of the gaster) is concave and forms a sharp angle with the dorsal face of the postpetiole.
Erect hairs are moderately abundant and in general are short (up to 0.5 mm on the dorsum of the mesosoma, most hairs < 0.3 mm in length). The scape has several short (up to 0.2 mm) erect hairs in addition to fine suberect pubescence. Appressed golden pubescence is moderately abundant on the head, the mesosoma and more abundant on the dorsum of the gaster.
Most surfaces are punctate and moderately to strongly shining. The mandibles are mostly smooth and glossy with scattered punctures, the dorsum of the head and surface of the scape are densely and finely punctate but shining. The mesosoma has scattered punctures, but most surfaces are at least moderately glossy, the mesopleuron, and the side and lower posterior face of the propodeum have poorly defined striae. The petiole is finely punctate and mostly glossy, as is the dorsum of the gaster. The metasternal process consists of two broad lobes with tiny teeth at the apex.
From Mackay and Mackay (2010): The female is a large (total length 14 mm) dull black ant with dark brown appendages. The mandible has eight well-developed teeth, which are approximately equal in size, except for the apicalmost tooth, which is slightly larger. The preapical tooth is smaller than the others. The anterior border of the clypeus is broadly convex; the head is widest at the level of the eye and the posterior margin is strongly concave. The head length and head width are 3 mm. The malar carina is absent and the eye (maximum diameter 0.6 mm) is located approximately ½ diameter from the anterior margin of the head. The ocelli (maximum diameter 0.15 mm) are located approximately two diameters apart. The scape (2.5 mm) nearly reaches the posterior lateral corner of the head. The pronotal carina is well developed and slightly overhangs the side of the pronotum, especially anteriorly. The propodeal spiracle is slit-shaped. The petiole is narrow when viewed in profile with a slightly concave anterior face and a broadly rounded posterior face and meet at an angle at the anterior edge. The subpetiolar process forms a broad lobe anteriorly. The anterior face of the postpetiole is strongly concave and forms an acute angle anteriorly with the dorsal face.
Erect hairs are present on the mandibles, clypeus, dorsal and ventral surfaces of the head, sides of the head, shaft of the scape, dorsum of the mesosoma, legs, dorsum of the petiole, the subpetiolar process and all surfaces of the gaster. Appressed golden pubescence is present on most surfaces but does not hide the sculpture.
The dorsal surface of the mandible is smooth and glossy with scattered punctures. The head is punctate, as is the mesosoma, the petiole and the gaster, with most surfaces only weakly shining.
Males are not known for this species.
