1. Antennae, long retractile into head capsule. Toothed ligula and maxillary palp with seven apical stylets well developed............................................................................................... Tanypodinae View in CoL
- Antennae non-retractile. Ligula and maxillary palp strongly reduced............................................ 2
2. Procerci L/W at least 5. Premandibles absent..................................................... Podonominae View in CoL
- Procerci L/W, rarely more than 4. Premandibles present...................................................... 3
3. Ventromental plates well developed and with conspicuous striation, if without striations [ Stenochironomus View in CoL ] then plates raised laterally and fused to the maxillae throughout more than half their width.................. Chironominae View in CoL ........... 4
- Ventromental plates vestigial to well developed, when well developed never with striations.......................... 6
4. Antennae subtended by distinct tubercles (pedestals). Lauterborn organs very large and conspicuous or occurring at the apex of elongated stalks.............................................................................. Tanytarsini View in CoL
- Antennae not subtended by distinct tubercles, Lauterborn organs not large or occurring at the apex of elongated stalks..... 5
5. Ventromental plates straight, bar-like with more or less parallel-sided margins..................... Pseudochironomini View in CoL
- Ventromental plates usually fan-shaped, if elongate then anterior margins curved and tapering towards posterior margins............................................................................................. Chironomini View in CoL
6. Third antennal segment usually annulated........................................................ Diamesinae View in CoL
- Third antennal segment not annulated.................................................................... 7
7. Antenna with 4 segments. Ventromental plates well developed...................................... Prodiamesinae View in CoL
