Description
The length of the workers is from 4.5 to 5.5 mm. Described in 1895 by the Italian Mirmecologist Carlo Emery under the original name Eciton melanocephalus and only in the working caste. They are distinguished by a two-color coloration (reddish-black) and the absence of a sub-petiolar protrusion (or it is very small in the form of a tooth), and by wrinkled granular mesonotum. The main color is reddish-brown, head and abdomen to black. Antennae of workers 12-segmented. The mandibular palpi is 2-segmented, the lower-labial palpi consists of 2–3 segments. Mandibles are triangular. Eyes missing or reduced to several facets. Ocellium and antennal grooves absent. Claws of the paws are simple without additional teeth on the concave surface. Propodeum rounded, without teeth. The labulae of the metathorax are located in its upper side or near the midline of the propodeum. The tibiae of the middle and hind legs with one comb spur. The stalk between the breast and abdomen in workers consists of two segments. The sting is developed. Perhaps the Neivamyrmex mandibularis males belong to the species N. melanocephalus or the species Neivamyrmex graciellae [2] [3] [5] [6] .
Lead a nomadic lifestyle . There are no permanent nests, except for temporary bivouacs [7] [8] [9] .
