It could be Chironomus (Chironomus). Is the pronotum projecting in lateral view? |

Then it's probably Chironomus. Glyptotendipes has a deep notch in the middle of the pronotum and it is normally distinctly recessed in lateral view. |

It looks like a typical member of subgenus Chironomus. Comparing illustrations, the thick superior volsella with right angle bend is similar to luridus, riparius, pseudothummi, and piger. |
