Similar in location, shape, and size to the galls of Coffeikokkos copeyensis Pujade-Villar & Melika. However, the galls of this new species are much more regularly spherical and its surface is not uniformly colored, but spotty. Diameter of gall measures 5 to 8 mm. They are formed, solitary or more frequently in groups, in stems of Quercus bumelioides Liebm. The surface of the gall is smooth and shiny; whitish, green or yellowish when fresh with red spots, becoming brown when mature. Monothalamic, with compact woody tissue internally containing the single larval cell (Fig. 8H).
