Tanypodinae View in CoL : Macropelopiini
The tribe Macropelopiini is represented in the region by several rather similar looking genera, differentiated only with difficulty in the larval stage. Several occur only at boundaries of the oriental region at elevation (e.g. northern Thailand, Burma, and the transitional zone of oriental and palaearctic China ( Tang & Niitsuma 2020b, Tang pers. obs.). Keys are based on extralimital larvae.

1’ Mandible with 1–2 small inner/accessory teeth and variably developed, tooth-like mola............................. 3
2(1) Mandible lacks dorsal (surface) teeth ( Fig. 6F View FIGURE 6 ). Ligula with all teeth tapering to anteriorly-directed point ( Fig. 6H View FIGURE 6 ). Pecten hypopharyngis with c. 20 short teeth..................................................... Psectrotanypus Kieffer View in CoL [small lotic, lentic waterbodies, P. lateralis Cheng & Wang View in CoL , P. varius (Fabricius) View in CoL , oriental China (inc.
