Morphology

Soldier

Soldier trimorphic. Large form: head brown, nasus dark brown, antennae yellowish brown, anterior lobe of the pronotum dark brown and the posterior lobe slightly paler, mesonotal and metanotal and abdominal tergites yellowish brown, legs pale yellow. Hairs on the head very few, slightly more numerous at the tip of the nasus, the margins of the pronotum with a few short hairs. Head nearly broadly rounded, widest slightly behind the middle, the posterior margin concave in the middle; in lateral view the posterior part of the dorsal margin of the head markedly raised, lower at the middle; the base of the nasus slightly raised, the tip of the nasus tilted up, the mandibular teeth distinct. Antennae mostly with 13 segments, occasionally 14; in the 13-segmented form segment 2 slender and shorter than segment 4, in the 14-segmented form segment 2 shortest. Pronotum saddle-shaped, the anterior lobe shorter than the posterior lobe, the anterior margin incised in the middle, the middle of the posterior margin not distinctly incised; abdomen olive-shaped. Medium form: head brownish yellow, nasus reddish brown, anterior lobe of the pronotum pale reddish brown; head flatly rounded, widest near the middle, the tip of the nasus slightly tilted up, the mandibular teeth indistinct; antennae with 13 segments. Small form: head pale brownish yellow, nasus pale reddish brown; head broadly rounded, widest slightly behind the middle, the tip of the nasus slightly tilted up and rather slender, the mandibular teeth absent or indistinct; antennae with 12 segments.

Alate

Worker

Head of the worker yellowish brown, the pale T-shaped suture visible, antennae pale yellow, mesonotal and metanotal and abdominal tergites pale brown, legs pale yellow. Head nearly circular, widest near the antennal sockets, postclypeus arched, antennae with 14 segments; the posterior margin of the apical tooth of the left and right mandibles equal to or slightly longer than the anterior margin of the first marginal tooth, and in the right mandible the posterior margin of the first marginal tooth shorter than that of the second marginal tooth. Pronotum saddle-shaped, the incision in the middle of the anterior margin distinct, abdomen olive-shaped. In the paler-headed form the chaetotaxy and head shape are as in the large form, the T-shaped suture indistinct, antennae with 13 segments.
