The Cubitermitinae are an Afrotropical subfamily of higher termites with 28 known genera and 147 species.Weidner, H. 1956.

The most well known genus of this subfamily is Cubitermes, which commonly build epigeal nests with one or more caps used to shield the nest against rainfall, giving them a characteristic mushroom shape.Treatise on the Isoptera of the world. (Bulletin of the American Museum of Natural History, no. 377). Krishna, Kumar.; Grimaldi, David A.; Krishna, Valerie.; Engel, Michael S. Volume 1; Page 123 Most members of this subfamily feed on soil humus. Due to their feeding habits, many species have a high pH within their digestive system, with Noditermes indoensis in particular exhibiting a pH around 12.28 within their anterior proctodeum; amongst the most alkaline environment known in a biological system.{{Cite journal |last=Brune |first=A. |last2=Kühl |first2=M. |date=1996-11-01 |title=pH profiles of the extremely alkaline hindguts of soil-feeding termites (Isoptera: Termitidae) determined with microelectrodes |url=https://www.sciencedirect.com/science/article/pii/S0022191096000364 |journal=Journal of Insect Physiology |volume=42 |issue=11 |pages=1121–1127 |doi=10.1016/S0022-1910(96)00036-4 |issn=0022-1910}}
Identification
The gut of workers have a specialized blind caecum/diverticulum connected to proctodeal 3 and a complex physiology that regulates the pH and oxygen supply in the gut compartments.{{Cite journal |last=Brune |first=Andreas |date=March 2014 |title=Symbiotic digestion of lignocellulose in termite guts |url=https://www.nature.com/articles/nrmicro3182 |journal=Nature Reviews Microbiology |language=en |volume=12 |issue=3 |pages=168–180 |doi=10.1038/nrmicro3182 |pmid=24487819 |s2cid=5220210 |issn=1740-1534|url-access=subscription }}
Soldiers have a generally subrectangular head capsule with a projection anterior to the frontal gland with the fontanelle being conspicuous and sunken in a pit or groove. The labrum is strongly bifurcated and the antennae have 14 - 15 articles (antennomeres).
