Pupa: gill with numerous (38–50) filaments; abdominal tuberculation absent; pleurites absent from segments VI & VII. Larva: mandible apex with spinous teeth markedly expressed; hypostomal teeth 5–7, poorly expressed; lateral hypostomal serrations absent; posterior tentorial pits rectangular; prothoracic proleg lateral sclerite L-shaped, lappets not commonly present; anal sclerite with posterolateral arms variously present; area between posterolateral arms and circlet of hooks with large number of campaniform sensilla; posterior proleg with large number (10,000 –17,000) of hooks; larvae occur in flows of high velocity.
