I think this is Metriocnemus, some species do have these purple coloration. I also think I see short antenna, which fit for Metriocnemus too |

It might be worth checking whether these magnificent colours are due to an iridovirus, although I understand that studies on chironomids attacked by iridoviruses show that they do not normally display the bright colours that other invertebrates do. (See p.256 of Yoshinori Tanada, Harry K. Kaya - 2012 - Insect Pathology.)

This is the typical color pattern within Metriocnemus hygropeticus agg. I have never seen any other colorpattern within this complex So I don't think it's a virus. |
