Genus Paraneotermes · 近新白蚁属

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

The alate has a distinct obtuse-angled bend on the posterior margins of the first and second marginal teeth of the left mandible, and the arolium is absent; the soldier, with mandibles short and strong relative to the head length, can be distinguished from Comatermes and Ceratokalotermes (see their respective entries).

Alate

Dark smoky brown; eyes small, about 0.28 mm in diameter, ocelli about 0.02 mm from the compound eye; antennae 14–15 segments; the first and second marginal teeth of the left mandible broader at the base than the third marginal tooth, their posterior margins slightly longer than the anterior margin of the third marginal tooth, with an obtuse-angled bend about 1/4 from the apex; molar plate of the right mandible nearly equal in length to the posterior margin of the second marginal tooth; pronotum slightly wider than the head, the anterior margin broad and shallowly concave; radial sector with 6–7 branches; media paler than the radial sector, weakly sclerotised; arolium absent.

Soldier

Head long, dorsoventrally flattened; frons slightly concave along the median line, inclined downwards towards the clypeus at about 35°; eyes colourless; antennae 13–15 segments, the third equal in length to the second; mandibles short and strong relative to the head length, with a basal tubercle; anterior part of the postmentum very broad; pronotum as wide as the head, the anterior margin broadly concave; femora distinctly swollen.
