Distribution map
GBIF has no georeferenced records for this genus, so this page has no genus-level map; see the family map for Kalotermitidae.
About the genus
This genus belongs to the family Kalotermitidae 木白蚁科; the site records 4 species.
Type species: Bicornitermes bicornis.
GBIF has no georeferenced records for this genus, so this page has no map; open a species entry to see its type locality and references.
Etymology
From Latin bi- (two) + cornu (horn) + 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 is difficult to distinguish from Bifiditermes; the soldier has a short, truncate head that is strongly frontal-shield-like, and the anterior margin of the pronotum is serrate; it differs from Epicalotermes in the shorter anterior margin of the third marginal tooth of the left mandible.
Alate
Yellowish brown; eyes large, diameter 0.41–0.46 mm, ocelli touching the compound eyes; antennae 12–15-segmented; anterior margin of the third marginal tooth of the left mandible distinctly longer than the posterior margin of the first and second marginal teeth, but not more than 1.5 times as long; molar plate of the right mandible distinctly shorter than the posterior margin of the second marginal tooth; pronotum narrower than the head; wings transparent, with colourless small papillae; media and cubitus with a common stalk beyond the wing suture; arolium absent.
Soldier
Head dark, short and truncate, anterior part steeply inclined; lateral frontal regions raised into distinct round lobes with a depression between them; the lateral frontal angles near the clypeus project forwards as a horizontal ridge connected with the dorsal margin of the antennal socket; another distinct angular projection anteroventral to the antennal socket; eyes colourless; antennae 11–15-segmented, the third segment subequal to the second or fourth; mandibles short, with a distinct basal tubercle; pronotum narrower than the head or as wide as the head, anterior margin raised, serrate and deeply concave.
