Systematics: Pseudaulacaspis sasakawai is very close to P. cockerelli, but is separated by the constant presence of submarginal macroducts on the 6th abdominal segment. In P. cockerelli, a few macroducts are rarely found in the submarginal region of the 6th abdominal segment, but these macroducts are irregular in position, occurring at times close to the marginal macroducts and at times rather close to the submedian macroducts. In P. sasakawai the submarginal macroducts of the 6th abdominal segment always forms a stable row (Takagi, 1970).
Structure: Adult female fusiform, with meso- and metathorax and basal three abdominal segments well lobed laterally and with the pygidium rather narrow; at full growth there is a slight indication of the swelling of the thoracic region (Takagi, 1970).
Biology: This species was collected at an altitude of 2440 m (Takagi, 1975).
General Remarks: Detailed description and illustration by Takagi (1970).
