Morphology
Key characters
In the soldier the head bears only scattered short hairs; head pear-shaped; distinctly narrowed behind the antennal sockets, widest near the posterior margin; posterior margin rounded, scarcely concave at the middle; nasus a slender tube; mandibles short and small, blunt, without pointed tips; antennae 12–13-segmented.
Soldier
Soldier with sparse pilosity on the head. Head pear-shaped, the lateral margins markedly narrowed behind the antennal sockets, widening again only from there backwards to near the posterior margin, widest near the posterior margin; posterior margin arcuate, not or scarcely concave at the middle. Nasus tubular. Mandibles without pointed tips. Antennae 12–13-segmented.
Worker
Worker with a large and conspicuous fontanelle situated near the middle of the vertex; the cutting edge between the first and second marginal teeth of the left mandible is not straight but undulating, and the undulation is gentle, an easily observed character of the worker of this genus.
Distribution
Oriental region; a component of tropical and subtropical areas, recorded from southern China.
Summary

The nasus is tubular and the mandibles lack pointed tips. Antennae have 12 or 13 segments. Workers have a large, conspicuous fontanelle and a wavy margin between the first and second marginal teeth of the left mandible. The genus is Oriental.
