Diagnosis: A boxwork of anostomosed longitudinal borings interconnected by short tangential ones in the pith of a cycad stem. Borings are 1 to 3 mm wide, they have no outer layer and most of them are filled with compact masses of excrement. Some borings contain individual fecal pellets having hexagonal cross-sections.
