Genus Fulleritermes · 富勒白蚁属

Morphology

The descriptions below are an adaptation of the original genus-level accounts; terms follow the meaning of the source, and the original is not transcribed verbatim.

Diagnostic characters

Coaton 1962 separated the genus from Coarctotermes on the incision of the cutting edge of the alate left mandible in front of the 3rd marginal tooth; the same feature occurs in Grallatotermes and Leptomyxotermes, but the compound eyes and ocelli of those two genera are much larger, and Grallatotermes has 13–14 ridges on the right molar plate. The molar plate of this genus has 7–9 ridges and a very weak to very strong concavity on the anterior edge near the base, the 1st molar ridge forming a coarse tooth. The soldier is monomorphic or dimorphic, the nasus cylindrical or conical, the head ranging from almost unconstricted to strongly constricted behind the antennae, the posterior lobe usually more than a quarter wider than the anterior part, antennae 12–13-segmented.

Alate

The apical tooth of the left mandible is as long as the 1st marginal tooth, and the distance from the apical tooth to the 1st marginal tooth is more than one-third of the distance between the 1st and 3rd marginal teeth (left mandible index 36–43); the cutting edge between the 1st and 3rd marginal teeth bears an incision that delimits the 3rd marginal tooth. The right mandible has the apical tooth and 1st marginal tooth nearly equal in length, the 1st marginal tooth bearing a small subsidiary tooth at its basal junction near the apical tooth, and the relative lengths of the cutting edges of the 1st and 2nd marginal teeth are variable; the surface of the molar plate has a very weak to very strong concavity on the anterior edge near the base, the posterior edge extending into a rounded wing, the 1st molar ridge forming a coarse tooth, the remaining 7–9 diminishing towards the base. Fontanelle slit-like, distinctly forked anteriorly, usually paler than the head.

Soldier

Monomorphic or dimorphic. Nasus cylindrical or conical. Vestigial mandibles with a small to medium-sized point. Head capsule from almost unconstricted to strongly constricted behind the antennae, the posterior lobe usually more than a quarter wider than the anterior part. Antennae 12–13-segmented.
