Key to genera of larval Chironominae View in CoL found
1. Ventromental plates wide and short, meeting at midline ( Fig. 20 View Figs , vmp). Antenna arising from pedestal ( Fig. 22 View Figs ). Lauterborn organs distinct, on elongate stems ( Figs. 22–24 View Figs , LO) ............ ................................................................................ Tanytarsus View in CoL
– Ventromental plates fan-shaped to semilunar, often well separated medially (e.g. Fig. 27 View Figs ). Antenna not on pedestal; Lauterborn organs variable, not on stems ( Fig. 25 View Figs ) ............... .............................................................. 2 (tribe Chironomini View in CoL )
2. Posterior body with trailing ventrolateral appendages arising from abdominal segment 8; segment 9 dorsally with a rounded protruding ‘hump’ ( Fig. 26 View Figs , arrow). Ventromental plates subtriangular, almost in contact medialy ( Fig. 21 View Figs , vmp).Antenna ( Fig. 25 View Figs ) as long as head ...................................... Zavreliella View in CoL
– Ventromental plates more semilunar, more widely separated medially ( Figs. 27, 30, 33 View Figs , 40–42, 46–47 View Figs , vmp). Antenna shorter than head....................................................................3
3. Antenna with 6 segments, Lauterborn organs on apices of 2 nd and 3 rd segments ( Fig. 28 View Figs , LO) ................... Conochironomus View in CoL
– Antenna 5-segmented, Lauterborn organs opposite on apex of 2 nd segment ( Fig. 31 View Figs ) ........................................................... 4
4. Labral setae SI and SII setae simple, blade-like ( Fig. 29 View Figs , SI, SII); labral lamella absent ( Fig. 29 View Figs ) ............ Parachironomus View in CoL
– Setae SI seta plumose ( Fig. 34 View Figs , SI), SII not blade-like; labral lamellae present ( Fig. 34 View Figs , ll) ............................................... 5
5. Outer face of mandible with basal striations ( Fig. 32 View Figs , arrow) .............................................................................. Chironomus View in CoL
– Mandible lacking basal striations ........................................ 6
6. Ventromental plates narrow, only ca. twice as wide as long ( Figs. 40–42 View Figs , vmp) ........................................... Dicrotendipes View in CoL
– Ventromental plates broader, at least 2.5 times as wide as long ( Figs. 46–47 View Figs , vmp) ............................................................... 7
7. Dorsocentral elongate sclerite on head (e.g. Fig 44 View Figs , frons) with antero-median ‘fenestra’ ( Figs 43–45 View Figs , fen, arrows). Premandible with 5–6 teeth (as in Fig. 35 View Figs , pmd) ..................... Kiefferulus Dorsocentral View in CoL head sclerite without ‘fenestra’ (e.g. frontoclypeus, Fig. 57 View Figs ). Premandible with 2–3 teeth (as in Fig. 36 View Figs ) ............. .............................................................................. Polypedilum View in CoL
