Genus Tumulitermes · 冢白蚁属

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

Alate with the 1st tooth of the left mandible distinctly larger than the 2nd, head broadly oval and often narrow anteriorly, fontanelle near the middle of the head, antennal segments rather long, pronotum broad, wing surface punctate and sparsely hairy (Taf. III, Fig. 12); soldier with an apical process on the mandibles (weak but certainly present in T. tumuli and T. apiocephalus), head capsule not constricted behind the antennal sockets, nasus relatively long and narrow, conical to cylindrical, head oval (Taf. III, Fig. 13). Distinguished from Subulitermes by the presence or absence of the soldier apical process, and from Rotunditermes by nasus and head shape. Holmgren considers that in general body structure the genus differs very little from Eutermes s. str. and is the link connecting the group to Eutermes s. str.

Alate

Head broadly oval, usually narrowing anteriorly; fontanelle about at the middle of the head; antennal segments relatively long; pronotum broad; wing surface punctate and sparsely hairy (Tafel III, Fig. 12). 1st tooth of the left mandible distinctly larger than the 2nd; clypeus about as long as half its width, or shorter and strongly raised, oval, pale yellow.

Soldier

Mandibles with a more or less distinct apical process; head capsule not constricted behind the antennal sockets; nasus relatively long and narrow, conical to cylindrical; head oval (Tafel III, Fig. 13).
