The morphology of juvenile stages of Parachipteria bella (Sellnick, 1928) and P. willmanni Hammen, 1952 is described and both these and adults are illustrated. The respective juvenile stages of P. bella are smaller than those of P. willmanni. In P. bella the anterior region of the prodorsum is distinctly reticulated, but that of P. willmanni is not. In P. bella the gastronotal setae, especially those of the d- and l-series, look relatively longer and thicker than in P. willmanni. Keys to the juveniles and adults of Parachipteria bella, P. willmanni, Achipteria coleoptrata (Linnaeus, 1758) and A. nitens (Nicolet, 1855) are proposed.
