Key to genera of larval Tanypodinae   found

1. Body segments bearing lateral longitudinal dense setal fringe ( Fig. 1 View Figs , fr). Mentum (technically dorsomentum) distinct, toothed ( Fig. 7 View Figs , m) ............................................................................ 2

– Body segments lacking setal fringe. Mentum or dorsomentum indistinct, not toothed ( Fig. 15 View Figs , m) ..... 4 (tribe Pentaneurini   )

2. Dorsomental teeth weak, not aligned on plate ( Fig. 2 View Figs , dmt). Mandible strongly hooked ( Fig. 3 View Figs , md) ........... Clinotanypus  

– Dorsomental teeth strong at margin of plate ( Fig. 7 View Figs ). Mandible straight to curved, never hooked ( Fig. 6 View Figs ) ............................ 3

3. Ligula with median tooth largest, all teeth directed anteriorly ( Fig. 4 View Figs ); pecten hypopharyngis absent. Mandible squat, with expanded base and short apical tooth ....................... Tanypus  

– Ligula with median tooth smaller than medially-curved sublateral teeth ( Fig. 5 View Figs ); pecten hypopharyngis present ( Fig. 5 View Figs ph). Mandible with many spine-like teeth (arrowed) on mesal surface ( Fig. 6 View Figs ), without distinct basal tooth .... Fittkauimyia  

4. Basal segment of maxillary palp divided into 2 or more sections ( Fig. 8 View Figs , mp) .......................................................................... 5

– Basal segment of maxillary palp simple, undivided ( Fig. 9 View Figs ). ............................................................................................... 6

5. Submentum with seta S 10 linearly aligned with S Sm and S 9 setae, with VP lying posterolateral to that alignment ( Fig. 10 View Figs ). Division of maxillary palp into 2 sections at about 1/3 from segment base ........................................................ Paramerina  

– Submentum with S Sm nearly aligned with VP and S 10 seta, with S 9 anteromedial to that alignment ( Fig. 11 View Figs ). Basal palp segment divided into 2–5 sections ( Fig. 8 View Figs ); if only 2 sections, then division is anterior to basal 1/3 ................. Ablabesmyia  

6 One claw of posterior parapod dark, with inner teeth ( Fig. 12 View Figs ). VP more posterior than any ventral cephalic seta ( Fig. 13 View Figs ) .. ............................................................................ Monopelopia  

– All claws of posterior parapod pale, simple. S Sm far posterior to VP ( Fig. 14 View Figs ) ............................................................. Larsia
