Etymology
From Greek eu- (well) + kryptos (hidden) + Latin 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 soldier converges with Cryptotermes in having a shield-like frons; the alate wing venation and mandibles resemble Neotermes, but the anterior margin of the forewing scale is nearly straight or slightly convex, whereas it is more convex in Neotermes.
Alate
Body yellowish brown; eye diameter 0.43 mm, ocelli touching the compound eye; antennae 14–16 segments; mandibles resembling those of Glyptotermes, the first and second marginal teeth of the left mandible equal in length to the third marginal tooth, the posterior margin of the second marginal tooth of the right mandible slightly longer than the molar plate; pronotum narrower than the head; anterior margin of the forewing scale nearly straight or slightly convex; radial sector with 5–6 branches, the first branch at about half the wing length; media strongly sclerotised, nearly parallel to and close to the radial sector; arolium present.
Soldier
Head dark brown, frons shield-like, short and thick, the sides rather straight and parallel, slightly constricted at the antennae; frontal region smooth, concave, without sculpture; a sharp circular ridge between the frons and the vertex, anterior part and sides; frontal region projecting forward beyond the mandibular bases; front steep; antennal sockets about 1/3–1/2 of the head length from the anterior margin of the head; eyes present but indistinct, narrow; antennae 11 segments, the third shorter than the second; dorsal surface of the labrum not visible; mandibles short, broad at the base, with a distinct basal tubercle; postmentum short, oval; anterior margin of the pronotum rising abruptly from the posterior, gently arched part, the anterior margin angularly concave and distinctly serrate in dorsal view; femora not swollen.
