Etymology
Etymology uncertain; -termes from 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 mixed segment of the worker is elongate, its inner end inflated into a white spherical mesenteric diverticulum; this character is shared with Anoplotermes sensu stricto and distinguishes the genus from the remaining South American soldierless termite genera. The main difference from Anoplotermes s.s. lies in the enteric valve: the enteric valve of this genus consists of 6 pads, each with 10–20 long spines extending into the paunch (P3); the fontanelle of the alate is larger and more elongate.
Alate
Compound eyes and ocelli medium-sized. Fontanelle medium-sized, appearing as an elongate white spot between the two eyes. Pronotum semicircular in dorsal view, with several hundred small setae and several tens of long setae. The posterior margins of the mesonotum and metanotum slightly concave, the angles rounded.
Worker
Very small to small, head width 0.49–0.62 mm (genus-level measurement). Head capsule white, covered with more than 100 small setae. Fontanelle almost invisible. Fore tibia inflated at the middle. Digestive tract very similar to that of Anoplotermes sensu stricto: the midgut and proctodeum overlap, forming a distinct long mixed segment whose mesenteric part is inflated at its inner end into a white spherical diverticulum. The enteric valve is inserted into the extension of the paunch and consists of 6 sclerotised pads with a well-developed sclerotised armature.
