Soldier
Head red-yellow-brown, the nasus darker; head markedly constricted at mid-length; vertex with two hairs; antennae 13-segmented (segment 3 longer than segment 2 or segment 4 but less than twice segment 2, unlike N. dorix); mandibles with extremely small points, almost indiscernible; thorax nearly concolorous with the head; legs relatively short for the body. Measurements (mm): head length 1.39–1.47, head width 0.78, pronotum 0.18×0.44, hind tibia 1.10. Much smaller than N. dorix; N. coarctatus has a smaller posterior part of the head behind the constriction and a thicker nasus; N. clepsydra has a black head; N. tenebricus has a longer head and unpointed mandibles.
