Etymology
From Latin calcar (spur) + termes.
The etymologies in this section are analytical breakdowns; the roots follow Brown (1956).
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 resembles Glyptotermes; the soldier is distinguished from other genera by a stout spur on the outer side of the apex of the fore tibia, much larger than the other two apical spurs.
Alate
Dark brown; eyes small, diameter 0.29–0.34 mm, ocelli touching the compound eyes in most species; antennae 13–14-segmented; posterior margin of the first and second marginal teeth of the left mandible equal in length to the anterior margin of the third marginal tooth, the notch between them lost in most species to form a concave cutting margin; posterior margin of the second marginal tooth of the right mandible slightly longer than the molar plate; pronotum slightly narrower than the head; venation as in Glyptotermes; arolium present.
Soldier
Head dark, thick, semicylindrical, distinctly bilobed with a V- or U-shaped depression between the lobes; anterior face of the frons steep, the slope steeper or shallower than vertical, in some species the dorsal margin projecting forwards or concave between the upper margin and the clypeus; in some species the ventrolateral part of the mentum forms an angular projection between the mandibular base and below the antennal socket; eyes distinct or indistinct, colourless; antennae 10–12-segmented, the third segment short and unspecialised; mandibles usually short and broad, with or without a basal tubercle; pronotum narrower than, equal to or wider than the head, anterior margin shallowly angular or distinctly concave; outer side of the proximal end of the fore tibia with a stout spur, much larger than the other two apical spurs.
