Gnathamitermes perplexus, the long-jawed desert termites or tube-building termites, is a species of termite in the family Termitidae.

It is found in Central America and North America.

[1][2][3] The species creates tunnels, with both colony founders and workers transporting sand to excavate tunnels using their mandibles.

[4] The species is particularly susceptible to infectious nematodes such as Steinernema riobrave.
