The first record of Trichotanypus Kieffer (Diptera, Chironomidae: Podonominae) in the Tibet Plateau of China, with description of a new species.

Trichotanypus hani sp. nov. is described here based on the male, pupa and larva collected in the Tibet Plateau. The new species is characteristic by the elongated posterolateral heel of gonostylus in the male, bifid thoracic horn in the pupa and 8-10 mandible teeth in the larva. This is the first formal record of Trichotanypus from East Asia, indeed the first far-outside the circum-Arctic area.
