Key to larvae of subfamilies and tribes of Chironomidae View in CoL View at ENA

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
