Chironomus plumosus (Linnaeus, 1758)

Chamutiová, Tímea, Hamerlík, Ladislav & Bitušík, Peter, 2020, Subfossil chironomids (Diptera, Chironomidae) of lakes in the Tatra Mountains an illustrated guide, Zootaxa 4819 (2), pp. 216-264 : 249

Chironomus plumosus - type ( Figs 74, 75 )

Fourth lateral tooth of the mentum longer than fifth. Mandible with three inner teeth.

In our material, however, there are also individuals combining the plumosus - type mentum with anthracinus type mandible and the other way around ( Fig. 73 and 75 ). In this case, the shape of the mentum should be indicative for the type. Considering the great amount of Chironomus species, more study is needed to define more morphotypes.
