Termitaradus avitinquilinus is an extinct species of termite bug in the family Termitaphididae known from several possibly Miocene fossils found in the Dominican Republic.

The amber was produced by the extinct Hymenaea protera, which formerly grew on Hispaniola, across northern South America and up to southern Mexico.

The holotype fossil is composed of a complete adult individual that was collected from an unidentified amber mine[1] in fossil-bearing rocks in the Cordillera Septentrional mountains of northern Dominican Republic.

Grimaldi and Engel's 2008 type description of the new species was published in the natural sciences journal American Museum Novitates.

[1] The two paratype specimens are preserved in a single piece of amber in close association with a worker caste Mastotermes electrodominicus termite.
