Based on the material described below, the generic diagnosis for Parachironomus male ( Cranston et al. 1989; Spies et al. 1994), pupa ( Pinder & Reiss 1986) and larva ( Pinder & Reiss 1983) must be emended as follows. Pubescent ventral expansion of superior volsella in adult male hypopygium usually absent. Pupal cephalic tubercles usually present, and stout setae D5 placed on large and prominent tubercles on tergites III–VII may occur. Larval mentum sometimes with 6th lateral tooth larger than 5th and set forward, and ventromental plates with anterior margin strongly scalloped.
