[The Amrine catalog has three entries associated with Bucida buceras [Terminalia buceras]:

Colomerus bucidae (Nalepa 1904), a valid species with synonyms Eriophyes buceras and Colomerus bucidae
Relationship: "Erineum in leaf bulges- upward."
Note: "There may be three separate species here: one causing erineum, one causing leaf galls, and one causing the flower galls described by Trotter, 1929. This host plant and its mites need further study."

Colomerus buceras (Trotter 1929), tentatively asserted as a deprecated synonym of Eriophyes bucida (Nalepa, 1904)
Relationship: "Greatly elongated, slender, hollow, horn-shaped outgrowth on flower, about 19 cm long (instead of the normal fruit measuring only 5-6 mm) and about 2-4 mm thick. The gall cavity contains numerous fleshy irregular emergences. Some of the galls on inflorescence develop into witches' brooms."
Note: "This appears to be a valid species that is distinct from and precedes Eriophyes buceras Cromroy, 1958. This mite was missed by Davis et al., 1982, and by Amrine & Stasny, 1994."

Colomerus buceras (Cromroy, 1958), a deprecated synonym of Colomerus bucidae
Relationship: "Deformed fruit, leaf erineum, and two types of galls [galls were not described]."
Note for C buceras reads: "Is this the same species described by Trotter in 1917 (Eriophyes buceras Trotter, 1929)? If they are different species, then this mite needs a new name. The symptoms may be describing 2 or 3 species."]
